This paper describes the chain of data acquisition and procedures implemented in order to develop value-added products, in raster and vector formats, and its incorporation into the Web-GIS system for the epidemiological management of Chagas desease. The operational implementation is detailed using open source technologies such as GRASS-GIS. Thus, the steps required to incorporate environmental layers...
Customer demand for electricity supply is vastly increasing due to urbanization and changing needs. Thus electrical utilities need to accurately determine load profiles for different sectors of the supply area, so that new customers can be seamlessly added. To obtain such information a customer connectivity model needs to be developed and implemented such that historical customer data from various...
School Bus Routing (SBR) is a typical instance of Vehicle Routing Problem (VRP). Meanwhile SBR has unique and important objectives, such as safety of the students and total amount of time the students stay on the bus that other VRPs usually do not need to consider. When all these factors are considered, the school bus routing problem becomes a complex combinatorial optimization issue which the traditional...
The high number of WMW from Gunung Kidul and the problems they face, prompting the need for an effort to take action to create economic independence of former WMW. On the other side, the vast potential of waqf (endowment) utilization can be optimized to be an asset to push economics independence of former WMW. A visualization is required to facilitate the process of decision-making for waqf distribution...
The exploitation of distributed energy resources and problems associated with islanded energy grids are important in optimizing sustainability of electricity supply, where microgrids play a major role in the decentralized and dispersed production. As defined, a microgrid is a group of interconnected loads and distributed energy resources within clearly defined electrical boundaries that acts as a...
OpenStreetMap is a collaborative mapping tool that was created in 2004 by computer student, Steve Coast. The initial idea of the project targeted mapping the United Kingdom region exclusively, however, researchers from other countries became interested and were added as well. Since thousands of users insert new data into the instrument, on an ongoing basis, the quality of that data raises concern...
It's a new trend for architecture designs that using virtual reality technology in BIM in the life cycle of construction but it still lacks of applications for integration management. GIS is a spatial information system in the professional form of data acquisition, processing, analysis, management and display. Because their application domains are different, the file formats are not compatible that...
Zaozhuang city in Shandong province is changing from the mining city to the tourist city, the tourism industry is developing rapidly, but the tourism management is relatively backward. In order to provide technical support for Zaozhuang tourism management, according to the characteristics of tourism resources in Zaozhuang, the author designs and develops the tourism resources management system. Combined...
This paper implemented the web-based GIS Hotels Business Tourism Site in Khartoum state. The motivation as well as the problem statement is the lack of spatial data and geographical informations of Business Hotels tourism in Khartoum state, hence, lead to the unavailability of web based Business Hotels tourism, also the lack of research papers in this field. One of important goal is the way of supporting...
Haze has becoming a yearly occurrence in Malaysia. There exist three dimensionsto the problems associated with air pollution: public ignorance on quality of air, impact of air pollution towards health, and difficulty in obtaining information related to air pollution. This research aims to analyse and visually identify areas and associated level of air pollutant. This study applies the air pollutant...
The article is dedicated to give an assessment of possibility of the applicability of web-based geographic information systems (GIS) within the micro geo-marketing researches. Description of micro geo-marketing data domain, its key features and objectives are given. Functional model of the data collection process is presented. Authors formulate requirements for micro geo-marketing web-GIS and suggests...
We present here the development of an Open Source Geographic Information System (OSGIS) tool using MapWindow GIS and petrel software to prove its efficiency for different applications. Geographic Information System (GIS) is a computer system capable of capturing, storing, analyzing, and displaying geographically all types of data. MapWindow is free of charge, extensible geographic information system...
The aim of this work is to study and develop a methodology for the first stage of deployment of a Small Hydropower Plant (SHP), the Estimate Hydroelectric Potential, stage in which is studied the favorable and unfavorable situations to the deployment of small plants. Basing on environmental and technical criteria of a watershed, according secondary data provided by agencies and institutions responsible...
Due to the development of Geographic Information Systems (GIS), tasks that relied on extensive ranges of time and resources they have been simplified. At present, there are a variety of alternative SIG, hampering the decision making when choosing a suitable GIS for a specific project. Therefore, in this paper a framework that supports decision-making in the selection of GIS in an organization of any...
This paper focuses on evaluation of the Geographic Information Systems utilization for solving residential recyclables collection routing problems. Recyclables collection is considered as a part of reverse logistics to which a specific routing problem is connected. Recycling itself is one of the sustainable solutions intended for Smart Cities. Recycling rate increase in recent years and always high...
In order to fuse seismic information and spatial information together while reducing the investment cost of software for seismological departments, we introduced openGIS to the analysis and prediction of earthquake and create Map Manager module of Earthquake Analysis and Prediction System that supports the function of displaying seismic information on map and simple Spatial analysis and map editing...
Digital elevation model (DEM) images present the elevation information of earth's surface in the form of an image in floating point or integer format. While integer type has substantial space saving capabilities, they show stair-case or ladder effect when an image is draped on DEM using 3D visualization software. Due to wide availability of DEM data in integer format, it becomes imperative to develop...
The traditional sequential ways of spatial data processing lags in the efficiency of executing the queries. The modern parallel processing technique, the MapReduce, is used extensively for big data analysis. This paper analyzes the synthetic large spatial data-set on the MapReduce and ArcGIS to check the similarity of the outputs generated through the parallel framework and the specialized GIS software...
Smart grids require not only smart tools to automatize grid operation and planning processes but also require smart approaches to maximize utilization of the capabilities of those tools as well. Geographic information systems (GIS) provide an integrated suite of software for visualizing the system data, tools for network optimisation, and a range of automation and information processing systems which...
The process of Solar Farm site selection is a complex issue because it involves many criteria and many factors that are classified as problem Multi-Criteria Decision Making (MCDM). With computer technology, it is possible to analyze systematically the MCDM complex problems through computational intelligence techniques. Many methods have been developed to solve optimization problems of Solar Farm site...
