Geographical Information System (GIS) technology integrates hardware, software and spatial data for capturing, storing, updating, managing, analyzing and displaying geographical data and phenomena. Spatiotemporal analysis of such phenomena is one of the major tasks of a GIS. In this paper, we use GIS for the modeling of the exposure to direct sun light in a rural road network. When a vehicle is...

Essential genes are thought to encode proteins that carry out the basic functions to sustain a cellular life, and genomic islands (GIs) usually contain clusters of horizontally transferred genes. It has been assumed that essential genes are not likely to be located in GIs, but systematical analysis of essential genes in GIs has not been explored before. Here, we have analyzed the essential gene...

In this research, Integration of GIS and Cellular automata modelling was used to develop a simulation model that can represent spatial distribution pattern of urban growth in Bandung Area. CA can be considered as analytical engine of GIS, which plays in important role in modelling and simulation of spatialtemporal processes. Another approach to integrate CA and GIS in this research are to devel...

Accomplishing an effective routing of emergency vehicle will minimize its response time and will thus improve the response performance. Traffic congestion is a critical problem in urban area that influences the travel time of vehicles. The aim of this study is developing a spatial decision support system (SDSS) for emergency vehicle routing. The proposed system is based on integration of geospa...

Terrorist attacks at the World Trade Center (WTC) in New York City and the Pentagon on September 11, 2001, not only affected multi-level structures in urban areas but also impacted upon their immediate environment at the street level in ways that considerably reduced the speed of emergency response. In this paper, we examine the potential of using real-time 3D GIS for the development and implem...

Various methods for automatic change detection in multi-temporal LANDSAT-TM images are described. In contrast to most previous work in change detection, which has operated at a pixel level, we operate at a parcel level (within a minimum size of 25 Ha). This makes it easier to employ structural measures (e.g. based on edges, corners, and texture) as well as correlation methods since these approa...

In this paper, the application of High-Performance Computing (HPC) techniques in processing of geospatial data in Geographic Information System (GIS) is presented. We evaluate two parallel/distributed architectures and programming models: Message Passing Interface (MPI) over Network of Workstations (NoW) and Compute Unified Device Architecture (CUDA) on Graphics Processing Unit (GPU) in well-kn...

this research was aimed to investigate the condition of the existing roads and designing road network based on forest management plan at armardah, baneh. using analytical hierarchy process (ahp) method, the important layers of slope, aspect, forest type and distance to villages and resorts, were weighted and ranked. maps were produced to weighted layers generated in gis to find suitable regions...

The main objectives of this paper are, designing and balancing of Water Distribution Network (WDN) based on loops hydraulically balanced method as well as using Geographical Information System (GIS) methodology with the contribution of EPANET. GIS methodology is used to ensure WDN’s integrity and skeletonized a proper and functional WDN by using Network Analyst utilizing the geometric network a...
