Visual Analysis of Social Media Data on Experiences at a World Heritage Tourist Destination: Historic Centre of Macau

The burgeoning field of sustainable tourism in historically significant urban districts has derived increasing attention in tandem with broader urban economic development. The perceived image of a tourist destination significantly affects tourist consumption behaviors and destination choices, while negative evaluations provide destination managers with insights for targeted improvements to tourist amenities, thereby contributing to the sustainable development of these historically significant districts. This study leveraged Python 3.12.3 software to collect online textual data from popular tourism websites, specifically Ctrip 8.71.4 and Mafengwo 11.1.7. Then, ROST CM6.0 software facilitated high-frequency word analysis, network semantic analysis, and sentiment analysis to outline the perceived image and characteristics of the Macau Historic District, a UNESCO World Heritage site, from the perspective of tourists. The findings are as follows: (1) The image of the Historic Centre of Macao as a tourist destination comprises four primary dimensions: cultural (16.02%), landscape (30.85%), emotional (16.97%), and local (36.16%). (2) Tourists perceive the Historic Centre of Macao as a blend of dynamism and tranquility, tradition, and modernity. (3) Emotional evaluations of the Historic Centre of Macao as a tourist destination are primarily positive (85.45%), whereas negative sentiments constitute 5.76%, with recurring themes pertaining to overcrowding, high prices, a lack of interactive experiences at attractions, excessive commercialization, and insufficient public rest facilities. These findings offer valuable directives for the future planning and development of tourism in Macau, a city recognized for its World Heritage status. (4) In summary, the thematic image of the Historic Centre of Macao can be considered authentic, romantic, and commercialized.

Comparative Analysis of Yi Lacquerware Ornamentation in Liangshan and Dafang

This paper explores the evolution of lacquerware ornamentation from traditional to modern expression in two Yi lacquerware regions in China, Liangshan, Sichuan and Dafang, Guizhou, through comparative analysis. Elements from nature, plants, animals and productive life are extracted as the basis of traditional Yi lacquerware ornamentation, focusing on their ornamental nature. However, under the influence of modern civilisation, lacquerware ornamentation has gradually incorporated some creative or modified thematic images, marking a response to the evolving needs of contemporary society. Adopting the sense of order theory and formal analysis theory as theoretical guides, this paper compares the formal characteristics, organisational structure and stylistic expression of lacquerware ornamentation in Liangshan and Dafang, revealing their distinctive visual expressions influenced by culture, history and art.

USING GEO-SPATIAL DATA AND DATASET FOR CROPLAND MONITORING IN DARKHAN-UUL AND SELENGE PROVINCES, MONGOLIA

Abstract. The central agricultural region is relatively pleasant in terms of nature and climate of our country, and due to the use of land for multiple purposes, the ecological status of the land has been greatly changed. It is necessary to use many types of layered data and use many types of thematic image results in agricultural monitoring and research, which is a necessary land use. These data will be carried out by various branches of research, and the modelling of each data into a unified database with geographical connections will allow for integrated evaluation and thematic drawing, and the use of geo-spatial analysis decision-making system is required. The purpose of this work is to carry out agricultural land monitoring research using remote sensing methods and advanced technology, to develop a unified methodology, to enrich the data of the points of the monitoring network database, to create an interdisciplinary geo-database, and to develop recommendations for further measures to be taken. It will cover 304,000 hectares of 17 soums of Selenge province and 36,000 agricultural lands of 3 soums of Darkhan-Uul province. A geodatabase was created for the monitoring survey of agricultural land, and a map and route for the field survey was prepared before starting the field survey. The database includes 21 sub-district boundaries, team boundaries and agricultural monitoring points, cadastral data of cultivated and agricultural land, agricultural soil data, satellite data and topography data.

VPL FOR CULTURAL HERITAGE MONITORING: SAMPLING AND COMPARISON OF PHOTOGRAPHIC IMAGES

Abstract. In the last decades, ICT strongly support cultural heritage conservation, management, valorisation and communication activities. Digital systems record series of data in real time, facilitating the automation of comparison, control and preventive evaluation activities aimed at the conscious management of the phenomenal reality based on the interrelationship between different information. According to these premises, this contribution presents first results of a research activity aimed at testing VPL parametric tools aimed at mapping environmental data and phenomena involving architectural surfaces and explicitating the comparison between data by graphical alert system. VPL tools are designed for a thematic image colour sampling. The main goal is monitoring the state of conservation of decorated architectural surfaces or artworks placed in unfavourable environmental conditions to facilitate preventive and intervention activities. The case study chosen to test this approach and digital tools is the fresco preserved in the Filangieri Hall of the State Archives in Naples.

The dynamics of normalized difference vegetation index (NDVI) of natural and agricultural landscapes in Alexandrovsky and Novoselitsky municipal districts of the Stavropol territory during the active vegetation period in 2020 based on high resolution spatial images

The article discusses the changes in the NDVI on the territory of the Alexandrovsky and Novoselitsky municipal districts of the Stavropol Territory during the active vegetation period of 2020. The data source were Sentinel-2 thematic images, the spatial resolution of which is 10 m. The schematic maps reflecting the distribution of the NDVI by dates with minimal cloud cover in June-September 2020 have been compiled and analyzed. To explain the spatial and temporal pattern of changes in the areas occupied by different gradations of the NDVI, the data of the Aleksandrovsky weather station for 2020 (the course of temperature and precipitation during the year) were analyzed here as well. The use of remote sensing data and corresponding vegetation indices allows mapping various processes and phenomena in the GIS sphere, and the compiled maps can be used to solve a wide range of theoretical and practical tasks, including crop yields assessement.

Разливы нефтепродуктов на водной поверхности: методы анализа данных дистанционного зондирования Земли при их выявлении

High rate of scale & space distribution of the damage done to the natural environment dictate the need for ultra-fast detection of World Ocean’s oil pollution. The article discusses various methods for oil spills detection on the water surface by processing remote sensing data obtained by different satellite systems: active (Sentinel-1 [IW]) and passive (multispectral images: medium resolution Landsat-8 [OLI], Sentinel-2 [MSI] and high-resolution PlanetScope). The results of enhancement and thematic image processing by automated interpretation methods, such as threshold filteringof the quality assessment channel (Landsat-8: Collection 1 Level-1), radar image’ speckle filtering, estimation of in-dexes and supervised classification based on spectral signatures are presented.

Hemingway's Short Stories: Reflections on Teaching, Reading, and Understanding ed. by Frederic J. Svoboda

Reviewed by: Hemingway's Short Stories: Reflections on Teaching, Reading, and Understanding ed. by Frederic J. Svoboda Ellen Andrews Knodt Hemingway's Short Stories: Reflections on Teaching, Reading, and Understanding. Edited by Frederic J. Svoboda, Kent UP, 2019. 144 pp. $24.95. A recent addition to the Teaching Hemingway series, Hemingway's Short Stories: Reflections on Teaching, Reading, and Understanding, edited by Frederic Svoboda, is a highly useful volume for high school and college instructors who often introduce students to Hemingway through one of his famous short stories. As Mark P. Ott mentions in his Foreword, the essays included here "revise our understanding not only of Hemingway but also how to refresh his work for students" (x). Building on the work of Paul Smith and Joseph J. Waldmeir, to whom the book is dedicated, Svoboda enlists leading literary critics to analyze thirteen Hemingway stories, several of which are frequently anthologized such as "Indian Camp"; "Big Two-Hearted River"; or "Hills Like White Elephants," and some that readers may not know as well, such as "Cross Country Snow" or "A Simple Enquiry." Essays model a variety of teaching practices and thematic focuses to enable close reading for high school, college, and technical school students. As Svoboda remarks, close reading is useful "for literary study in general—or even for any college course requiring attention to details" (xi). After Svoboda's introduction, Peter L. Hays begins the volume with the first short story from In Our Time, "First Things: Teaching 'Indian Camp.'" Focusing his approach to the story with undergraduate and graduate students, Hays takes readers through the main events in the story, posing questions aimed at eliciting the class's perceptions of the Native Americans, Dr. Adams, Nick (his young son), and Uncle George. Hays highlights often overlooked details of light imagery, the contrast in landscape at the beginning and end of the story, varying interpretations of Dr. Adams' comments, and the Native American husband's motive for his suicide. This first essay bodes well for the "hands on" advice for instructors in this collection. Several more essays focus on In Our Time selections, showcasing a variety of teaching techniques. Janice Byrne's essay "Hemingway's 'The End of Something' for High School Sophomores" features pre-reading activities about Hemingway's experiences in World War I, as a way of preparing them for Nick's break-up with Marjorie. Byrne follows the biographical detail with a two-minute writing activity about Nick and then Marjorie for individual students or small groups. Another option, according to Byrne, is to ask small [End Page 137] groups to consider the thematic images in the text, such as the past, love, or alienation. She also finds the setting of the demolished sawmill at the beginning of the story ripe for discussion. Byrne ends her essay with a number of post-discussion activities. Another take on how World War I affects a character is Judith Siegel Henn's essay "The Education of Harold Krebs, or Approaching Ernest Hemingway's 'Soldier's Home' with Engineering Students in Israel." Seeking information about her students' understanding of Hemingway in general and in their ease of understanding the story, Henn asks student to complete pre-reading questionnaires which she includes in the essay. Once students have read the story, Henn identifies dilemmas or problem areas in the story, such as the meaning of the photos at the beginning or Krebs' "disgust with duplicity," and asks small groups to analyze those areas before reporting to the class. Quoting from student papers, Henn marvels at how well the story invites "reading between the lines." Frederic Svoboda's contribution, "The Things That Nick Adams Carried to the 'Big Two-Hearted River,'" with an acknowledged link to Tim O'Brien's story and novel, demonstrates the realism of Nick Adams's fishing journey by physically demonstrating to his Michigan students that a 65-pound backpack can indeed account for every item mentioned in the story. Paired essays in the collection include two on "The Battler," also from In Our Time. These essays discuss the tricky issue of race in the story, focusing on the character of Bugs, the African-American "caretaker" of the white...

Despair and Hope: The Healing Power of Listening

Despair is defined in the dictionary as the complete loss or absence of hope. Many if not most individuals feel a deep sense of despair, made more intense by the loneliness that is part of their lives. The power differentials between those who receive services and those who provide services often intensify this sense of despair and loneliness. It is in that relationship between the powerful and the powerless that loneliness and despair start to build, because there is no bridge between the people who serve and those being served. Those of us who provide services and supports to people in need have been taught to be objective and factual, but facts are only part of the story, the roadway so to speak. The foundations of the bridges between people are found in the emotional connections, the places where the stories of their lives take shape. In order to gain the whole story we must listen to the feelings, where the thematic images behind the words present the story of this person’s life.

ЛИНГВО-КУЛЬТУРНАЯ ХАРАКТЕРИСТИКА ЛЕКСИКО-СЕМАНТИЧЕСКОГО ПОЛЯ «RÉALITÉ RUSSE» В РОМАНЕ Ф. БЕГБЕДЕРА «ИДЕАЛЬ»

The article discusses and defines the content of the lexical and semantic field «Russian reality» in modern literature on the example of the novel by F. Beigbeder «Au secours, pardon» («Ideal»). The author of the selected work F. Beigbeder is a popular modern French writer, the winner of the famous literary award «Renaudot». F. Beigbeder is known in the literary world as a prominent representative of mass literature. The images created by the writer on the pages of novels are understandable and close to the reader. The style and linguistic units used in the works deserve special attention, since F. Beigbeder’s novels are characterized by intertextuality, the method of quoting cult classical works, the principle of ambivalence, and autobiography. The text under consideration is no exception. In it, the abovementioned techniques and principles are applied by merging the author with the narrator, shifting styles and genres in the work, using irony, and the presence of thematic images and representations. The analysis of entire thematic blocks in a work of fiction remains an urgent linguistic problem, since lexical and semantic research allows us to consider thematic groupings of words from the point of view of psycholinguistics, thenational cultural component. In the work under study, a significant place is given to the formation of images, ideas, stereotypes, and mythologies about Russian reality, which served as a rich material for building a lexical and semantic field with the same name. In addition, the image of Russian reality is reflected in the novel not directly, but through the perception of female characters, through the interpretation and explication of the concept «female beauty». This fact is even more interesting for the description of the selected field. The main results of the research are, first of all, the formation of the lexical-semantic field «Russian reality» (réalité russe) on the basis of linguistic units selected by the continuous sampling method from the text of the work in French and the linguistic-cultural analysis of the factual material with the indication of the percentage of filling the core and periphery of the analyzed lexical-semantic field.

Images of Amhara women in oral poetry

The objective of this article is to describe the thematic images of Amhara women in oral poetry. The study is based on field research conducted in rural areas of Western Gojjam and Awi Zone. The data was collected by observation, interview, and focus group discussion. For documentary evidence, twelve informants were selected with the use of a purposive sampling technique. The research method employed was ethnographic qualitative description. The result revealed that the images reflected through oral poems address women mainly as wives, their particular aspects refer to love, woman’s attitude towards marriage issues, divorce, and include general knowledge, understanding of the life and personages within women’s worldview. By the same token, oral poetry portrayed those women as inferior to men. Finally, the study recommended a further research on oral literature of Amhara region of Ethiopia.

An Ontology-Based Framework for Integrating Remote Sensing Imagery, Image Products, and In Situ Observations

Along with the rapid development of remote sensing satellites and sensor network technology, vast amounts of remote sensing imagery and in situ observations have been accumulated. Further, various researchers and agencies have released a variety of thematic image products. These heterogeneous observations are therefore difficult to utilize comprehensively. In this study, an ontology-based framework for integrating remote sensing imagery, image products, and in situ observations was developed. It was extended based on the Semantic Sensor Network (SSN) ontology in the Web Ontology Language (OWL). The detailed process of ontology construction and rule establishment was demonstrated. Combined with some actual remote sensing imagery, image products, and in situ observations, semantic queries based on DL Query and SPARQL were conducted to establish the rationality and feasibility of the ontology and framework.

ХУДОЖНЯ СТРУКТУРА ТЕМАТИЧНОГО ЖІНОЧОГО ОБРАЗУ З ФОЛЬКЛОРНИМИ МОТИВАМИ: ЕТАПИ СТВОРЕННЯ

The aim of the article. The aims of the article are to provide the integrated study of the art structure features of the thematic image development for cultural events by means of makeup, costume, additions; to determine the specifics of the make-up artist vision influence on the image character; its correspondence to the general concept of the event.Historical method, analytical method and comparative analysis method have been used in the pre-project research. The art-associative method, which provided the combination of the female image from the Slavic mythology calendar rites with the modern vision of fashion and female canons of beauty, has been used in the research project process. The sequence of a thematic image creation process for the event with competitional and concert program has been highlighted in the article. The image creation process can be implemented in three stages: the search for an idea and the thematic female image conceptual content definition; the expression means search and necessary materials preparation; the stylization and realization of the image. The importance of external associations, that arises, according to the concept of the event, as a reflection in minds of historical folklore heritage about the autumn calendar cycle customs and rites, on the stage of the image idea search have been determined. The project idea is to embody the interaction of a young, direct perception of the world by a young girl with the cultural experience of ancient Ukrainians and is implemented on the principle of using contrasts – shape, color and texture. The thematic image of the event has been formed with the help of associations with ancient Slavic mythology female images. The scientific novelty is in the definition of the concept, design methods and means of thematic female image development based on the appeal to the ancient Ukrainian cultural heritage. The art-associative method has been identified as the most effective method for the folklore motives based image formation. The art structure of the thematic female image for the cultural event has been revealed; the modern author vision in the expression means selection has been actualized. The sequences of thematic female image development for the cultural and art event, which embodies the concept of the event and perform the strengthening function of the impression and influence on visitors, have been represented. Three stages of project implementation from the conception stage to realization stage have been stated and implemented.

Integration Between Cerebral Hemispheres Contributes to Defense Mechanisms.

Defense mechanisms are mental functions which facilitate coping when real or imagined events challenge personal wishes, needs, and feelings. Whether defense mechanisms have a specific neural basis is unknown. The present research tested the hypothesis that interhemispheric integration plays a critical role in defense mechanism development, by studying a unique sample of patients born without the corpus callosum (agenesis of the corpus callosum; AgCC). Adults with AgCC (N = 27) and matched healthy volunteers (N = 30) were compared on defense mechanism use across increasing levels of developmental maturity (denial, least; projection, intermediate; identification, most). Narratives generated in response to Thematic Apperception Test images were scored according to the Defense Mechanism Manual. Greater use of denial and less identification was found in persons with AgCC, compared to healthy comparisons. This difference emerged after age 18 when full maturation of defenses among healthy individuals was expected. The findings provide clinically important characterization of social and emotional processing in persons with AgCC. More broadly, the results support the hypothesis that functional integration across the hemispheres is important for the development of defense mechanisms.

Infomages: Embedding Data into Thematic Images

AbstractRecent studies have indicated that visually embellished charts such as infographics have the ability to engage viewers and positively affect memorability. Fueled by these findings, researchers have proposed a variety of infographic design tools. However, these tools do not cover the entire design space. In this work, we identify a subset of infographics that we call infomages. Infomages are casual visuals of data in which a data chart is embedded into a thematic image such that the content of the image reflects the subject and the designer's interpretation of the data. Creating an effective infomage, however, can require a fair amount of design expertise and is thus out of reach for most people. In order to also afford non‐artists with the means to design convincing infomages, we first study the principled design of existing infomages and identify a set of key chart embedding techniques. Informed by these findings we build a design tool that links web‐scale image search with a set of interactive image processing tools to empower novice users with the ability to design a wide variety of infomages. As the embedding process might introduce some amount of visual distortion of the data our tool also aids users to gauge the amount of this distortion, if any. We experimentally demonstrate the usability of our tool and conclude with a discussion of infomages and our design tool.

Examining the PALSAR-2 Global forest/non-forest maps through Turkish afforestation practices

ABSTRACT Forests and afforestation have significant importance, given the present course of World’s climate resulting from our insensitive behaviours, policies, ambitions, etc. Turkish Forest Service has departments, sole purposes of which are to combat desertification through afforestation, flood control, and watershed rehabilitation works. Majority of the works is carried out in the semi-arid central part of the country, which is known as the Irano-Turanian phytogeographic region. Hydroelectric dam projects, which have extensively been conducted to produce energy and to harness the rivers when needed, have been at the centre of these efforts in the region. Afforestation works, which have long been used to safeguard dam reservoirs, have always been associated with such projects because they are implemented even prior to water deposition. They along with the country’s managed forests are looked after as the natural forest cover. Improvements in remote sensing at this point enabled the agencies to diversify their efforts in monitoring the natural resources and strengthening the decision makers’ hand in management preferences in both global and regional scales. There are various data produced through the classification of satellite imagery representing the existence or the percentage of forests in any location on Earth. In this study, Global Phased Arrayed L-band Synthetic Aperture Radar PALSAR-2/PALSAR mosaic and forest/non-forest maps of Japan Aerospace Exploration Agency (JAXA) and Global Forest Cover Change (GFCC) thematic image tiles of National Aeronautics and Space Administration (NASA), which are two of the widely accepted such data, were compared to one another and to our control results produced by a pixel-based classification method to assess the performance of afforestation works around seven major hydroelectric dam reservoirs situated within the central part of Turkey. The results showed that Global PALSAR-2/PALSAR forest/non-forest maps were somewhat capturing the trend, but overly exaggerating the ground facts up to 1064%. GFCC epochs, on the other hand, did not yield sound results in this semi-arid part of Turkey. Latter data could not even capture the successfully afforested sites.

Efficacia dell’arte, strategie di rete e approccio trasformativo a paesaggio e patrimonio alpino

Ever since 2011, Dolomiti Contemporanee (DC) has been operating on the contemporary identity of the mountain, and on the state of the Landscape, as well as the cultural, historic, and architectural Heritage inside the region of UNESCO’s Dolomites. Its research takes shape in the reactivation of large, issue-heavy industrial archaeology sites and compounds: former factories, former social villages, iconic architectural creations, with a great historical or aesthetic value, abandoned and underutilized, immersed in the powerful nature of the Dolomitic region. DC works on the redefinition of the mountain’s identity, building re-innovative and thematic critical images. In this sense, we refuse to recognize as an acceptable identity for the Alpine landscape the hotchpotch of stereotypical reductions which deliver a bland and reified vision of it, one that almost always involves plain and simple economic and touristic exploitation of the asset, to the detriment of its real potential’s nourishment. DC’s practice puts at the centre the need for re-enhancement and functional re-use of a few exceptional sites, which must be re-processed and re-activated. It is a responsible necessity of care and an opportunity for the regeneration of extraordinary underdeveloped sources of potential at the same time. Contemporary art, innovation culture, network strategies, those are some of the “techniques” through which such sites, so important in the past and now lifeless, are tackled, and morphed into cultural and artistic production centres, finally operative again, engines able to represent and provide new value to the territory.

Selection and evaluation of optimal segmentation scale for high-resolution remote sensing images based on prior thematic maps and image features

Multiscale segmentation is the premise and key step of geographic object-based image analysis (GEOBIA), but scale selection remains a challenge in multiscale segmentation. Over the years, scale selection and evaluation in image segmentation has been extensively explored and many methods have been developed. In these methods, when a scale is chosen or evaluated, all the features are generally extracted from images. In addition, an optimal scale is generally selected based on the pre-estimation of the statistical variance in remote sensing images or determined based on the postsegmentation evaluation of segmented results. In this study, a method was proposed to identify the optimal scale of each segmented object during the segmentation through combining the a priori thematic map knowledge with image features. First, 25 image segmentations were obtained using multiresolution segmentation algorithm of Definiens Professional 9.0 with different scales. A global score (GS) value was assigned to each segmentation based on the calculation results of the weighted variance and global Moran’s I and the single-scale optimal segmentation result was determined according to each GS of 25 segmentation scales. Second, the image feature complexity information and the a priori thematic map complexity information of each segmentation object were extracted to calculate complexity values for each object. Third, the optimal scale of each segmentation object was determined through the iterative calculation with the multithreshold method. Finally, the segmentation results of the proposed method were evaluated. The proposed method was applied to process Gaofen-2 (GF-2), GF-1, Korea Multipurpose Satellite (KOMPSAT-2), IKONOS, QuickBird and WorldView-2 high resolution satellite images to obtain the segmentation results and classification results, compared with results obtained of the optimal single-scale segmentation and the unsupervised evaluation method. The experimental results of GEOBIA showed that the method was helpful for generating the segmentation object with the optimal scale.

Possibilities of GIS-technologies in implementing large-scale mapping during field practices of students-geographers

Experimental results of remote satellite data processing with different resolution from 3 to 60 m of bands are discussed in the article. The purpose of the article is to present and justify various options for using satellite imagery data and technologies of geographic information systems (GIS technologies) to solve various problems, taking into account previous research experience. The main material. The author suggests using Sentinel-2 and PlanetScope to compile large-scale maps of territories of different sizes. Based on the improvement of the methodology (previously used by the author), it is proposed to distinguish plant groups as indicative objects of indicative contours using remote sensing data. The second reference object is the contours of water bodies. We propose using colors (RGB), shapes and roughness to identify the contours of objects, but given the actual material of the field outputs to key areas. These characteristics can indirectly determine geomorphology. Based on spectral characteristic images, we consider the seasons, vegetation periods, and territory. During the filed practice students process a data set for different periods and analyze this information to study landscape changes. Based on studies from 2015 to 2019, a database for landscape monitoring of the protected area is being formed. The author with students and other researchers have determined that it is necessary to separately analyze northern and southern parts of the Slobozhansky National Nature Park. QGis and ArcGis tools allow you to prepare data and do overlay analysis to compile a hypothesis map, and then the resulting map. Conclusions and further research. It is established that the number of classes and the classification method depend on the properties of the objects of study. The best results were shown by isolating the contours of plant communities by the method of automatic classification by identifying key areas. It has been experimentally established that the decoding of satellite images PlanetScope gives the best results in small areas. For decoding of a larger area, Sentinel-2 gives the best results, the thematic image data of which is more generalized. Based on the information received from thematic maps, we have attributive data on the topography, geological structure, soil for each contour. All information will be used for the landscape monitoring base in the Slobozhansky National Nature Park.

Modificações paisagísticas e implicações térmicas no distrito administrativo de Belém, Pará

As modificações paisagísticas no uso e cobertura da terra podem implicar em alterações na dinâmica de ecossistemas e no clima local. Assim, objetivou-se verificar se o padrão de uso e cobertura da terra contribui para a existência e ou aumento de ilhas de calor no distrito de Mosqueiro, Pará. Foram levantados dados qualitativos por meio de entrevistas não formais com moradores para se conhecer as formas de uso e manejo das propriedades. Os dados quantitativos foram obtidos através de imagens temáticas da ilha correspondentes ao período menos chuvoso da região nos anos de 2010, 2013 e 2015. A classificação do uso e cobertura da terra na ilha de Mosqueiro seguiu o critério não supervisionado. Os dados de temperatura de superfície (TS) foram obtidos por meio dos valores de radiância espectral, da banda termal dos satélites Landsat 5 e 8. Para determinação de ilha de calor, considerou-se a resultante da diferença das temperaturas entre a classe de área urbana e a de floresta. No período de 2010 a 2015, constatou-se redução de área em 9,1% de floresta, pelo crescimento da infraestrutura urbana e pelo desmatamento na região, fato corroborado com a percepção dos moradores locais. Essas modificações resultaram em mudanças na TS, com aumento médio de 5.15°C, mesmo que não se tenha constatado a ocorrência de ilha de calor no espaço urbano. Diante do exposto, verificou-se que as variações da TS estão inteiramente relacionadas às mudanças nas classes de uso e cobertura da terra na ilha e que tende a intensificar sem o planejamento ambiental adequado.
