Utilization of Geographic Information System(GIS) in Determining the Suitability of Fisheries Locations Cultivation of Freshwater Fish Ponds in South Aceh Regency

The potential of freshwater aquaculture area in South Aceh has not been optimally pursued; this is due to the limited technological and information capabilities, institutions and funding. The purpose of this study was to map the suitability of freshwater aquaculture land by utilizing the Geographic Information System (GIS) and multi criteria analysis in South Aceh. Determination of land suitability is done through the Multi Criteria Evaluation (MCE) and application of Geographic Information Systems (GIS). The results of the analysis show that the appropriate location (S1) is 81.55% (of the total area sample area) and the location which is not suitable is 18.45% (of the total area sample area). This indicates that the coastal areas of South Aceh have potential freshwater aquaculture areas.

Characterizing the spatial mismatch between intimate partner violence related healthcare services and arrests in Miami-Dade County, Florida

BackgroundRoutine screening and intervention for intimate partner violence (IPV) in healthcare settings constitutes an important secondary prevention strategy for identifying individuals experiencing IPV early and connecting them with appropriate services. Considerable variation in available IPV-related healthcare services exists and interventions are needed to improve the quality of these services. One way to prioritize intervention efforts is by examining the level of services provided in communities most at risk relative to local incidence or prevalence of IPV. To inform future interventions, this study examined the spatial relationship between IPV-related healthcare services and IPV arrests in Miami-Dade County, Florida, and identified predictors of the observed spatial mismatch.MethodsSurvey data collected in 2014 from 278 health facilities pertaining to IPV services were geocoded, computed into a density layer, and aggregated at the census tract level to create a population-based normalized comprehensiveness score (NCS) as a proxy for IPV-related healthcare resources. IPV arrests from 2011 to 2015, collected from the county court, were geocoded and summarized by census tracts to serve as a proxy for IPV prevalence. These measures were combined into a resource disparity score (RDS) that compared relative service density to relative arrest rates, where positive RDS represented over-resourced neighborhoods and negative RDS corresponded to under-resourced neighborhoods. We used correlation analyses and a two-phase spatial modeling approach to evaluate correlates of NCS and RDS.ResultsA spatial lag model did not yield an association between NCS and IPV arrests, demonstrating a spatial mismatch, which we visualized using a Geographic Information System (GIS). A spatial error model revealed that the percentage of white non-Hispanic residents was positively associated with RDS, while percent black non-Hispanic, median age, ethnic heterogeneity, and economic disadvantage were negatively associated with RDS.ConclusionsThese findings underscore the need to further evaluate the adequacy of IPV-related healthcare resources for secondary prevention relative to local IPV arrest rates, particularly within economically disadvantaged neighborhoods. Our approach demonstrates the utility of GIS for identifying potential priority regions for IPV prevention efforts and resource allocation.

Priority of The Forestry Extension Officer Distribution Based on Geographic Information System In Environment Problem Solutions

Magelang Regency is one of the regencies in Central Java Province that has forests as much as 32% of its area. The forest area continues to drop along with the many threats to the existence of the forest. Deforestation, critical land and forest fire are a widespread environmental problem in protected areas and cultivation. This will have an impact on the environmental quality that is essential for sustainable living. To minimize the impact, community awareness efforts need to be conducted through extension activities. Therefore, the existence of forestry extension as the forming actors of the environment-caring community becomes very important. The current competence and placement of forestry extension is not ideal compared to environmental issues and community needs. Utilization of Geographic Information System (GIS) through priority distribution modeling can help overcome this.

Identification of flood area in the coastal region using remote sensing in Karawang Regency, West Java

Flooding often occurs in the lowlands, while the area is usually a rice production centres which affects the rice crop. Rice fields is generally located on fluvial plains and usually located in coastal areas, with relatively lower altitudes than roads or settlements. Physically wetland is an area flooding hazard and wetlands tend to longer floods than surrounding areas. Flood-hazard areas are formed due to sedimentation and usually at the confluence of river. This area is a fertile area for agriculture, has shallow ground water which is well suited for residential and urban areas. Karawang regency is one of the largest producers of rice commodities in West Java, therefore the Karawang regency government faces a challenge in maintaining the level of rice production due to global climate change that worsen the threat of flood hazard, in addition to land use change and increasing population. Based on the results of the spatial analysis from period of 2000 to 2006 the wetland area have been converted up to 7,493 ha. For the period of 2006 to 2015 wetland area have been converted up to 14,416 ha. Utilization of Geographic Information System with a model of Cellular Automata - Marcov Chain is an appropriate method for studying the phenomenon of expansion of build ups land in coastal region. The primary data used in the research is a land cover map of 2000, 2006 and 2015, which were the results of the multispectral classification of Landsat. The prediction of land cover change for the next fifteen years shows a continuous increase in built up area. The expansion of built up area and the possibility of widespread flood hazard areas, have inverse relationship with the decreasing of agricultural land area.

GIS Utilization for Delivering a Time Condition Products

As population is increasing rapidly all over the world, the need for delivering products is being more difficult especially for conditional products (products with life time). Many Customers require conditional products to be delivered to their locations. Distribution center may have multi depots (multi store branches) instead of one depot. Every depot has limited number of vehicles to minimize cost. Capacities of these vehicles are based on two dimensions (weight and volume). Geographic information system (GIS) is used for localizing customers’ destinations. Then OD Cost Matrix is used to assign every customer destination to the least cost depot to be served from it. Finally Network analyst is used to solve the vehicle routing problem generating final route directions for every vehicle and calculating the best time for lunch break of drivers automatically. This case study is applied on Mansoura city in Egypt.

Enhancing Extension and Research Activities Through the Use of Web GIS

There have been numerous efforts aimed at improving geographic literacy in order to address societal challenges. Extension educators can use geographic information system (GIS) technology to help their clients cultivate spatial thinking skills and solve problems. Researchers can use it to model relationships and better answer questions. A program at Prairie View A&M University involves the use of virtual, field, and story map activities associated with Web GIS (online mapping) to expose participants to plant species identification and engage them in spatial thinking. We describe that program and demonstrate the utility of Web GIS as a tool for integrating experiential learning in agro-environmental sciences.

Advances in the biogeography of littoral environments: a multidisciplinary perspective

news and update ISSN 1948-6596 conference summary Advances in the biogeography of littoral environments: a multidisciplinary perspective 8 th Spanish Congress of Biogeography – Seville, Spain, 23–26 September 2014 A multidisciplinary perspective The Spanish Congress of Biogeography has con- vened biennially since 2000 as a spin-off of the Spanish Fieldtrip Workshops in Biogeography— held regularly since 1991—under the scope of Physical Geography. These meetings have brought together geographers dealing with biogeography at scientific, scholarly or professional levels and likewise are open to disciplines related to bio- geography. The number of contributions to this eighth congress exceeded those of previous meet- ings (Table 1). Applied biogeography had the high- est number of contributions, followed by struc- tural studies of animal and plant communities, and dynamic biogeography (Table 1). This rank- order appears a persistent trend through years, whereas fluctuating ratios between these areas indicate varying emphases in the research efforts of geographers within the field of biogeography. Vegetation and faunal systems in littoral environments was the leitmotif of the 8 th Con- gress, which centered on the progress made in their characterization, dynamics and conservation criteria. Littoral environments are especially vul- nerable to degradation due to urban sprawl aligned to tourism development (Malavasi et al. 2013). In Spain this situation was denounced in 2009 by the European Parliament on the Auken report (Auken 2009) which drew attention to these environments, or at least what remains of them. Key contributions in this congress focused on structural and dynamic studies of vegetation systems, and new conservation proposals 1 . Above all, two aspects were noteworthy: the utility of Geographic Information Systems (GIS) and the application of pioneering methods of inventory and conservation models. In addition to the main theme, there were contributions on non-littoral environments (including Caatinga and Atlantic Forest), which emphasized the potential for insights from inter- disciplinary approaches and paleo studies, and the relevance of disciplines such as Pedoanthracology, Palynology and Paleobiogeography. The main re- search on fauna (primarily amphibians and birds) discussed modelling techniques for species distri- bution models (SDMs) and ecological niche mod- els (ENMs), and advanced monitoring systems us- ing high-frequency GPS data-loggers. Biogeography of littoral environments The keynote speaker Jose Ojeda (University of Seville) talked about the principal trends in the access, management and dissemination of spatial information supporting biogeography, highlighting data quality, homogenization and accessibility (Vitolo et al. 2015). Over the last few decades Geographic Information Technologies (GIT) and ultimately GIS have proved to be a key point for studying and monitoring vegetation and fauna of different ecosystems (Guisan et al. 1998, Rodriguez et al. 2012). There are still few studies, however, developed in coastal dune systems. Levi Garcia (University of Las Palmas de Gran Canaria [ULPGC] Spain) presented a comparison of auto- mated versus manual methods for establishing the distribution of vegetation cover in arid sandy systems; the automated method led to a more objective, cost-effective and efficient analysis than the manual approach. The implementation of GIS has proved to be consistent in analysing the mo- bility of arid sandy systems (Rodriguez et al. 2009) and also the associated survival strategies of their vegetation cover. Antonio Hernandez (ULPGC) discussed the strategy of Tamarix canariensis to cope with burial by sand: the survival of young seedlings is higher in taller plants and in plants that are further away from the front of dunes. Advances in methodologies include a com- bination of phytosociological methods with new 1 See program abstract and 8 th Congress' Book for further information: http://congreso.us.es/viiiceb/en/programme.html frontiers of biogeography 7.1, 2015 — © 2015 the authors; journal compilation © 2015 The International Biogeography Society

The factors and criteria for prioritization of GIS utilization by libraries

Purpose – This paper aims to identify the impressive factors on choosing the type of the libraries and information centers and determining their significance and prioritizing them and finally determining the priority of each type according to the identified factors to implement geographic information system (GIS) in the library researches. Design/methodology/approach – A combination of documentary, Delphi and analytic methods was used in the current study. Due to the interdisciplinary nature of the topic in mind, different dimensions of the issue were firstly identified through reviewing the research literature. Then, the Delphi panel was formed and the factors and indices for choosing and prioritizing the libraries were extracted and finally the analytic-hierarchy and Topsis method was used for analyzing and ranking the data which were collected through a questionnaire. In this way, the instrument was devised by the researcher and the population under the study consisted of the professors in two fields of LIS and the GIS. The criteria include the “access to the library”, “being active”, “the number of sources”, “the size and space of the place”, “the library equipment”, “compatibility” each one include eight, seven, five, five, two and five factors, respectively. Findings – In the Delphi study, six factors including 32 indices were determined for prioritizing the libraries to implement the GIS in the library researches. The analytic-hierarchy method was applied to compare the factors correspondingly in terms of the degree of their significance. In this way, “access to the library sources”, “being active”, “the number of sources”, “the size and space of the place”, “the library equipment” and “compatibility” were identified as the factors on choosing the library type with the values of 0.39, 0.24, 0.16, 0.08, 0.07 and 0.06, respectively. Then, several types of the libraries were ranked and the findings show that academic libraries are prioritized as the first one for conducting the GIS projects. Originality/value – Employing the factors resulted from the conducted researches is recommended for choosing the libraries to implement the GIS, so that the researches in this interdisciplinary field become more organized. To extend the current study, the extracted factors and indices can be sent to the professors of the LIS from the other countries to elicit their insights and thereby, designing a standard international checklist for choosing the libraries and information centers in the GIS projects.

Locality Service Review and Planning with GIS: A Pilot Study of Spatial Analysis of Poverty Data in Hong Kong

Although the potential utilization of geographical information system (GIS) technologies in social service planning at a community level has been suggested for more than a decade, actual applications are still rare. This article reports on a pilot study in which service user records of a short-term food assistance project operated in Hong Kong are mapped and analyzed using a geographical information system. Spatial analysis of the data set reveals an understanding of the problem of poverty in the served region that may not be observed by using conventional statistical analyses. The visualization of service data makes information more comprehensible to practitioners and community stakeholders, and helps create an empowering environment in the service review and planning processes. The project is suggested to have demonstrated a new method in locality service planning.

Impact of geography on organ allocation: Beyond the distance to the transplantation center.

To illustrate the application and utility of Geographic Information System (GIS) in exploring patterns of liver transplantation. Specifically, we aim to describe the geographic distribution of transplant registrations and identify disparities in access to liver transplantation across United Network of Organ Sharing (UNOS) region 1. Based on UNOS data, the number of listed transplant candidates by ZIP code from 2003 to 2012 for Region 1 was obtained. Choropleth (color-coded) maps were used to visualize the geographic distribution of transplant registrations across the region. Spatial interaction analysis was used to analyze the geographic pattern of total transplant registrations by ZIP code. Factors tested included ZIP code log population and log distance from each ZIP code to the nearest transplant center; ZIP code population density; distance from the nearest city over 50000; and dummy variables for state residence and location in the southern portion of the region. Visualization of transplant registrations revealed geographic disparities in organ allocation across Region 1. The total number of registrations was highest in the southern portion of the region. Spatial interaction analysis, after adjusting for the size of the underlying population, revealed statistically significant clustering of high and low rates in several geographic areas could not be predicted based solely on distance to the transplant center or density of population. GIS represents a new method to evaluate the access to liver transplantation within one region and can be used to identify the presence of disparities and reasons for their existence in order to alleviate them.

Enhanced validity and reliability of spatial decision support systems (SDSS) for sustainable transportation decision-making

The use of spatial decision support system (SDSS) is widely defined by various scholars and research projects. One good example would be in the area of transportation planning. With the recent emphasis on the relationship between transportation and environmental impact, adoptable nature of geographic information systems (GIS) with its spatial data management received particular attention. This perspective especially serves the area of the preliminary plan for a new transportation corridor as the utilization of GIS enables researchers to pinpoint the changes in natural landscape as well as physical environment. There are, however, constraints in the coordinated use of SDSS and transportation planning. Especially, the validity and reliability side of SDSS have been constantly challenged by many scholars. Although SDSS provides an advantage to create multiple alternatives, its subjective weighting process sometimes questions effectiveness of the final outcome. Therefore, this study aims to relieve the two limitations by incorporating confirmatory factor analysis and raster-based suitability matrix under the domain of transportation planning. As a result, the following research questions were answered: 1) Using confirmatory factor analysis, do input variables group based on their underlying implications?; and 2) Does the suitability matrix reflects each route's suitability score based on its emphasis? The modeling process adequately meets the need for logical weighting and systematic grouping process, and the final outcome is also examined by a suitability matrix clearly indicating that the proposed SDSS supports for more evidence-based planning practice.

Spatial analysis of perinatal mortality rates with geographic information systems in Kocaeli, Turkey

To determine the spatial patterns of perinatal mortality in Kocaeli, Turkey using geographic information systems (GIS); to examine whether regional differences exist for the period selected; and whether these differences are linked to regional risk factors. Ecological research. Data were obtained from the linked birth-death records data registry maintained by Kocaeli Provincial Health Directorate. Mortality data are added to the geodatabase on a monthly basis. Spatial patterns of mortality rates were determined with GIS by mapping the case differences in the districts, and spatial autocorrelation was used to examine the spatial pattern of mortality rates in the region. Various risk factors contributing to spatial variation of perinatal mortality were revealed in the region. Districts with high mortality rates were shown to be sensitive to these risk factors. The results of this study confirm the direct link between perinatal mortality and poor environmental conditions in the study region. The analyses applied in the study showed that some complex demographic and socio-economic factors should be associated with perinatal mortality rates to identify the geographic patterns of mortality. Implementation of spatial tools within GIS for mortality data showed the efficiency of GIS in perinatal mortality surveillance. This study also demonstrated the capability and utility of GIS to clarify the geographical distribution of perinatal mortality rates in the study area.

Geographic information systems: A mixed methods spatial approach in business and management research and beyond

Numerous phenomena in business and management (BAM) research have a spatial context; yet, the analysis of place and space is under-utilized by many researchers. Thus, we provide a framework for helping BAM researchers think spatially. Specifically, we demonstrate the utility of geographic information systems (GIS) as a mixed research tool. We demonstrate how GIS applications can involve the combining of quantitative and qualitative research techniques, methods, approaches, data, concepts, language and, most importantly, technologies, thereby yielding mixed research. We outline the types of research questions that can be addressed using GIS applications. Further, we illustrate how GIS applications can enhance representation and legitimation of already-collected data. Finally, we discuss how the use of GIS can transform mono-method research (i.e., quantitative or qualitative research) into mixed research without compromising researchers' philosophical assumptions and stances (e.g., post-positivism, constructivism). In providing our framework, we contend that GIS applications increase the rigor of BAM research and enable researchers to explore complex phenomena through an integrative, recursive, and iterative analysis.

Preparation of Geography Teaching Materials through the Utilization of Geographic Information Systems (GIS) Software

In this study we present a model through a sample implementation the intention of which is to teach Geography teachers how to develop learning materials by using the Arc GIS rather than instructing them about material development of all sorts. Within this context different phases of material development such as maps, landforms and settlements are explained step by step along with the digitizing process of screen maps. A great number of geographical materials can be enhanced by teachers of Geography if they follow the steps illustrated by the Arc GIS programme. The materials prepared by Geography teachers and three dimensional images can be enlarged or zoomed out on the screen to figure out the effect of the scale on the map. The fact that our eyesight becomes narrow and details disappeare as we gain height can be concretized through this example. Besides teachers can explain visually how physical features are shown by using contour lines. For instance, it is observed on three dimensional images that the slope increases where the contour lines become more frequent in areas like hillsides, or vice versa. The appearance of contour lines or other landforms can be highlighted by these images as well. In a class at which topics like river valleys, plains, plateaus, etc. are supposed to be explained, these can be presenented with the help of visuals. Furthermore the relation between settlements and landforms can be made clear and easy to grasp through already developed materials. Geography teachers can develop materials or process certain data with various techniques (satellite images, air photographs) as they improve their skills of using the GIS. They can even digitize the images of Google Earth, an increasingly popular internet device and turn them into an easy-to-examine datum by means of the GIS. In this manner they provide acquired information and developed materials to their students and help them use an advantegous device in the long and tiring process of education. We therefore need further research to integrate GIS practices and materials with social sciences and Geography and also to detect factors which prevent students from using the GIS actively during their education. Both descriptive and experimental researches can be directed at determining possible influences of the usage of GIS based materials in Geography and social sciences. Studies which depend on quality investigation methods will specifically prove useful alike.
