Areal data have been used to good effect in a wide range of sociological research. One of the most persistent problems associated with this type of data, however, is the need to combine data sets with incongruous boundaries. To help address this problem, we introduce a new method for identifying common geographies. We show that identifying common geographies is equivalent to identifying components within a k-uniform k-partite hypergraph. This approach can be easily implemented using a geographic information system in conjunction with a simple search algorithm.

QGIS is a free and open-source software that allows viewing, editing, and analyzing georeferenced data. It is a Geographic Information System (GIS) software composed by tools that allow to manipulate geographic information and consequently to create maps which help to get a better understanding and organization of geospatial data. Unfortunately, maps created directly in the GIS desktop software are not automatically transferred to a website. This research aimed to compare publishing capabilities in different QGIS plugins to create Web Maps. This study analyzes four QGIS plugins (QGIS2Web, QGIS Cloud, GIS Cloud Publisher and Mappia Publisher), performing a comparison between them, considering their advantages and disadvantages, the free and subscription plans, the tools offered by each plugin and other generic aspects. The four plugins were tested in a specific case study to automatically obtain different Web Maps. This study could help users to choose the most adequate tools to publish Web Maps under QGIS software.

Digital technologies have contributed to the formation of a new theoretical and methodological approach to the study of society and they influenced the development of a new branch of knowledge i.e. digital sociology. The purpose of this article is to analyze the opportunity of using a geographic information system (ArcGIS) for the analysis of statistical data of the facts of protests which took place in Rostov Region over the past ten years (2009–2018). Street protests, rallies, demonstrations, strikes are the main barometer of the social and political tension of a society, an important indicator of the existence of social problems and contradictions that require solutions. The article provides an overview of existing databases, the methodology for the creation of the geographic information system “Protest activity of Rostov region” and the opportunity of its use, which generally depend on research goals and objectives. This product allows identifying the structure of social protest, its qualitative and quantitative characteristics, its dynamics in time and space with the visualization of the main trends and so on. The visualization of the centers of the social and political tension in the form of ready made electronic maps contributes to deeper understanding of political, social, economic or environmental processes that take place in the Don region at different times. The authors draw the conclusion that the GIS developed for this research provides an opportunity to identify latent threats and risks that can destabilize the social situation in Rostov region, and accordingly adjust the regional policy. The geographic information system “Protest activity of Rostov region” can be used both by researchers and experts from a wide range of scientific organizations and by authorities of various administrative levels.

With the development and application of information technology, the digitization of information management and the virtualization of physical models have become very important technical application fields in the world. The establishment of the 3D landscape model and the realization of the 3D geographic information system (GIS) are based on this, and there is not only a wide range of development prospects in many aspects such as urban planning and management, planning and design, local government construction, housing industry development, land monitoring and management, and environmental monitoring and evaluation. There are not only research studies and formulations but also a practical significance in other analysis, evaluation, decision making, and other departments. In recent years, the research of 3D city modeling has been developed rapidly, and most of the existing 2D-GIS can be transformed into 3D visual landscape. Based on the three-dimensional geographic information system and desktop drawing software AutoCAD, this paper takes the two-dimensional line drawing (DLG) of a residential district as the base map, expounds the design process of the three-dimensional simulation model of the urban community from the aspects of map preprocessing, building simulation model construction, texture mapping, and virtual visualization, and discusses the problems encountered in it. The main contributions of this paper are that this technology puts forward a new solution for the integrated corridor operation and maintenance management, greatly improves the intelligent management level of the integrated corridor operation and maintenance work, and simplifies the complex integrated corridor operation and maintenance management. It is helpful to improve the work efficiency of operation and maintenance, reduce the dependence of personnel, and respond to the long-term construction needs of the smart city at the same time.

Geographic Information System (GIS) is a computer-based information system used to process and strore geographic data or information. One of the health services in a hospital is Intensive Care Unit (ICU). One of the decision making in RSUD of Meranti Islands Municipality is based on the hospital activity report. The purpose was to map the patient distribution by using geographic information system application to prodce reporting using a map. The type of this research was qualitative descriptive. The research results based on the ICU patient distribution showed that the highest patient visit based on the sub-district is from Tebing Tinggi. Based on the gender, the most frequently treated patient is male. In the age category, the highest patient visit is elderly of 44 people, and the lowest children age group of 3 people. Based on the distribution, it can be concluded that the procedure of BPJS patient is appropriate and has similar procedure with general patient and SKTM patient. The suggestion includes creating patient distribution mapping based on the diesases to allow us to see the general patient distribution in ICU, which should be provided with excellent services, so that the patients satisfied with the services provided.

Correct assessment of river flow is necessary to resolve a wide range of problems in the management and use of water resources. Recently, research towards the use of geomorphologic instantaneous unit hydrograph (GIUH) coupled with other conceptual models approach for flood prediction from ungauged catchments has been intensified. Widespread accessibility to geographic information system and remotely sensed imagery which are powerful tools for acquiring model inputs is one possible reason. This study, therefore, aims at direct surface runoff (DSRO) prediction using the geomorphologic instantaneous unit hydrograph based Nash model (GIUH-Nash) from ungauged catchment. DEM obtained from Shuttle Radar Topography Mission (SRTM) having 30 m resolution is used to generate the catchment’s physiographic and geomorphologic characteristics with the help of quantum geographic information system (QGIS). Based on this information, the GIUH-Nash model is used to simulate DSRO for different storm events. A visual comparison of observed values to predicted values of the runoff hydrographs as well as statistical indices shows that DSRO could be predicted with reasonable accuracy provided complete understanding of the model development and it’s evaluation procedures are properly followed. In respect of this, some key aspects that affect the performance of the model have been suggested.

This chapter presents fundamental concepts and purpose of the Geographic Information System (GIS) to understand, deploy, monitor, and control the Smart Grid (SG). To enable existing power grid for two-way electricity flow, there is a need to consider deployment of a number of advanced technologies. The SG will have a huge number of devices which are capable of information exchange across the whole electricity network. The GIS is a computer based tool which has the ability to display useful information primarily in the form of labeled digital maps. This capability is useful for transformation of conventional electric grid to a SG by finding suitable locations for timely and economically affordable installation of SG components. Although GIS is in use for electric utilities, new research and advancements in enabling technologies have made it more suitable to play a bigger role in the SG.
