Investigation and modeling of physical development of urban areas and its effects on light pollution using night light data

The expansion of urbanization and unbalanced urban growth has attracted the attention of many urban planners and decision makers to the issues and consequences of urban population growth. In general, monitoring how urban areas are developed on a large scale is very important in order to plan urban development. However, in most cases, the lack of basic information in this area, especially in developing countries is one of the main obstacles to achieve this. With the development of human civilization and urbanization, the demand for artificial light has increased and this growth will continue. Found. Due to its lack of direct impact on daily life, light pollution has remained largely unknown and has rarely been studied. In this regard, the role of remote sensing techniques and data in identifying changes in the physical development of cities and changes in the amount of light is clearer than other methods. Using VIIRS satellite imagery, other satellite, digital and GIS data can measure and measure the physical growth of cities as well as the spatial and temporal distribution and extent of this type of pollution, and can even manage the risk of this pollution and Reach zoning. High-risk and dangerous areas. In this study, NPP images, travel time layer of Landsat 7 and 8 images have been used, which have been analyzed with the help of remote sensing and GIS techniques. The time frame considered in this study is 2012 to 2020.

Integrated CA model and remote sensing approach for simulating the future development of a city

Population growth and industrial development have resulted in the physical development of cities and transformation of land use, especially in the areas surrounding the City. Reviewing these changes and predicting urban growth through modelling can help environmental managers in making more informed decisions. The purpose of this research was to simulate the expansion of urbanization and also its prediction in the future using the SLEUTH model in Zanjan. In this study, Landsat and IRS images were used 2001, 2002, and 2003. Then, slope data, land use, exclusion, urban development, transportation, and landing were introduced to the Cygwin using the controlled classification method, to implement the SLEUTH model. The results of model prediction indicated a significant increase will happen in urban areas by 38.1% over the next 22 years. The results also showed that with SLEUTH model calibration, the projected growth has a high scattering coefficient, in which case topography limits the development and expansion of the City. In contrast, the coefficients of spread and slope of play with points of 96 and 94 have considerably grown, respectively. The conversion of these lands into urban areas will slow down from now until the next 22 years, and this further development will be achieved along with the main roads of the province, as well as the actual results of the current situation will be the evidence for that. The results of this study can provide further study opportunities for planners and decision makers to consider preventive and controlling factors into strategic decisions.

Potentials and barriers of physical development of the Ruodbar city using Remote Sensing and GIS

Background and Objective: Physical development of cities around the world is influenced by its natural geography and human interactions. Geographic data analysis is difficult without the use of geographic information and satellite data, and impossible in a complex case. In this study, potentials and barriers of physical development of the Ruodbar city using Remote Sensing and GIS be evaluated. Method: Firstly, in the ArcGIS software environment, using the AHP-FUZZY combination method the use of slope, gradient, land use, power lines, river, road and rail, fault and rural points are used to locate the urban sprawl. The output was extracted in the form of a map of AHP and fuzzy overlay into five groups with very good, good, moderate, weak and very weak potential. In order to expand the city's physical development by using a visual interpretation on Google Earth images for 2016, 2009, 2004 for 12 years, a map was drawn out as the result. Finally, the results obtained from the Geographic Information and Visual Interpretation System were compared. Findings: The findings of the AHP-FUZZY compilation show that 95.6% of the study area has very weak potential, 1. 52% has a weak potential, 1.17% has a moderate potential, 1.21% has good potential and 0.69% has a very good potential. And the findings from the visual interpretation method over the course of 12 years show that the development of the city is just Mehr Housing (a project done government). Discussion and Conclusion: Based on the findings of the AHP-FUZZY Compilation and Metrology Measurement, we concluded that most of the constructions have been implemented in unpredictable places in the city of Roodbar, which is influenced by natural and inevitable factors, including steep slope, abundant faults, permanent existence of Sefidrood river, and land use, most of which are gardens and forests and agricultural land and has prevented its physical development.

The circularity of the urban ecosystem material productivity: The transformation of biomass into technomass in Southern Patagonia

Cities are vortex of the anthropogenic accumulated matter: technomass. The urban metabolism captures ecological stocks from other ecosystems to produce technomass in a complex process involving stocks and fluxes, energy and information. As such, the physical development of cities is entangled with the material productivity of other ecosystems, where ecological stocks are appropriated and finally accumulated in the urban tissue after several transformations. The appropriation and accumulation of stocks are essential for the reproduction of the urban material structure. The appropriation of ecological stocks from other ecosystems is an iterative process generating particular urbanisation patterns. This paper analyses the spatial evolution of livestock activity and rising urban development as a metabolic relationship between two ecosystems located in Southern Patagonia, Chile: the steppe ecosystem and the urban ecosystem of Punta Arenas. This relationship leaves behind deep footprints in the urban tissue, in the form of splendid architecture arising from ecosystems’ appropriation. The architectural sedimentation found in the urban tissue of Punta Arenas is linked to the depletion of the steppe ecosystem’s ecological stocks. The Patagonian pastureland and the bourgeois architecture of Punta Arenas are the initial and terminal phases of a complex process of appropriation; the beginning and the end of a metabolic chain where biomass is transformed into technomass. The stocks are ecological at the origin and become, through socio-economic transformation, material sedimentation.

Hubungan Tingkat Kegiatan Pasar Tradisional Baru terhadap Perubahan Tata Guna Lahan Perdagangan Jasa di Kota Surakarta

<p><em>Surakarta</em><em> as a city of culture and commerce services has many economic facilities to develop the trade sector. One of those economic facilities is traditional market. Traditional markets that has just been made by the government to regulate activities of street vendors, hereinafter in this research is referred to as new traditional market. Among four new traditional markets in Surakarta have different activity crowds. Since new traditional markets were established, there was development of trade and services activities around it. In addition, there is also a theory stating that economic activities will cause physical development of city, especially in terms of trade and services land use. So this research has objective to find out how the correlation between levels of activity on new traditional markets in Surakarta with changes in land use around it becomes trade and services functions. This research uses a deductive approach and classified as correlational study. Research analysis technique used is: scoring analysis to assess level of activity on new traditional markets and qualitative relationship matrix analysis to assess correlation between level of activity on new traditional markets with each changes in land use of trade and services sub-variable. The results obtained that level of activity </em><em>on all new traditional markets in Surakarta has strong correlation to changes in type of trade and services land use around it, has moderate correlation to changes in basic building coefficient, also has strong correlation to changes in floor building coefficient around it.</em></p><p><em> </em></p><p align="left"><strong><em>Keywords: </em></strong><em>land use, new market</em><em>s</em><em>, trade and services</em></p>

Analysis of land suitability for urban development in Ahwaz County in southwestern Iran using fuzzy logic and analytic network process (ANP).

The ever-increasing development of cities due to population growth and migration has led to unplanned constructions and great changes in urban spatial structure, especially the physical development of cities in unsuitable places, which requires conscious guidance and fundamental organization. It is therefore necessary to identify suitable sites for future development of cities and prevent urban sprawl as one of the main concerns of urban managers and planners. In this study, to determine the suitable sites for urban development in the county of Ahwaz, the effective biophysical and socioeconomic criteria (including 27 sub-criteria) were initially determined based on literature review and interviews with certified experts. In the next step, a database of criteria and sub-criteria was prepared. Standardization of values and unification of scales in map layers were done using fuzzy logic. The criteria and sub-criteria were weighted by analytic network process (ANP) in the Super Decision software. Next, the map layers were overlaid using weighted linear combination (WLC) in the GIS software. According to the research findings, the final land suitability map was prepared with five suitability classes of very high (5.86%), high (31.93%), medium (38.61%), low (17.65%), and very low (5.95%). Also, in terms of spatial distribution, suitable lands for urban development are mainly located in the central and southern parts of the Ahwaz County. It is expected that integration of fuzzy logic and ANP model will provide a better decision support tool compared with other models. The developed model can also be used in the land suitability analysis of other cities.

The Paradigm of Physical Development and Growth Realization in the Arena of Future Changes in Guidance and Control of the City

Abstract. Physical development of cities is a dynamic and continuous process in which the physical space of the city expands vertically and horizontally. The growth of cities is one of the essential characteristics of urban societies, because change and evolution are among the fundamental and necessary features of any city. One of the problems facing humanity in the present century is increased and uncontrolled growth of cities, which has caused planners to seek a remedy. Among these problems, it can be pointed to the uncontrolled expansion of cities into suburbs where the construction is carried out without a previous plan. Physical development of cities is a dynamic process, and various natural and man-made (artificial) factors are effective in the formation and future development of the city. Achieving sustainable development requires awareness and recognition of the environment and identifying the factors affecting the development process of the city. To more deeply identify current issues and problems and make policy and plan for future developments of cities, it is necessary to recognize the factors and forces affecting the growth and development of them over the past decade. The present paper entitled “The paradigm of physical development and growth realization in the arena of future changes in guidance and control of the city” aims to investigate the factor affecting the physical development and urbanization growth in Yamchi-Iran. This study attempts to review the contribution of each of urbanization growth factors and determine the factors playing a role in the physical development and directing the urban development. Hence, the present study, based on a descriptive-analytical method and using the data available in the statistics center of Marand County as well as interview and observation, investigates the effective factors in the physical development of the city. The results of this research show that the physical development of the city has not been constructed in a balanced and principled manner; also, it can be said that the physical growth of the city has not been in harmony with the population growth; and natural and topographical factors have not played a major role in the physical development of the city. In addition, the peripheral results indicate that the initial core of the city has been formed on the Agh-Chay River which had been an old thoroughfare between Isfahan-Jolfa and has continued its growth trend. The final section of this paper addresses the localization of Yamchi and determining the direction of its urban development; the results indicate that the north and north-east directions of the city are suitable for the future development of it.
