In this paper, we propose some adaptation to Geographical Information System (GIS) components used in GPS based navigation system. In our design process, we adopted a user-centered design approach in collaboration with final users and Orientation and Mobility (O&M) instructors. A database scheme is presented to integrate the principal classes proposed by users and O&M instructors. In addition, ...

While the use of three-dimensional (3D) geographical information system (GIS) is becoming in rapid development and being used in various fields such as urban and regional planning, disaster management and planning, mobile navigation and etc., commercial and open source GIS software packages tend to offer 3D-GIS functionalities for their products. On the basis, GIS analysis functions are to prov...

This study develops a geographical information system (GIS) approach for automated processing of the Next Generation Weather Radar (NEXRAD) Stage III precipitation data. The automated processing system, implemented by using commercial GIS and a number of Perl scripts and C/C++ programs, allows for rapid data display, requires less storage capacity, and provides the analytical and data visualiza...

ABSTRACT: GIS can significantly contribute to correct interpretation of the signatures of slicks visible on synthetic aperture radar (SAR) images, providing a basis for analysis. Proposed geoinformation approach to oil spill mapping is presented. It includes integration of the geographical, remote sensing, oil & gas infrastructure data and slick signatures, detected in SAR images, in GIS. Vario...

In this paper, we apply software agent technology paradigm to a well-known problem of Geographical Information Systems (GIS) known as conflation. Conflation is the complex process of recognizing and removing inconsistencies in geographical feature datasets that are stored in multiple databases. Specifically, we show how the technological advantages of an agent system can be combined with expert...

Location information is a set of data describing an individual geographical location. This information can be used in many ways to provide information and entertainment services to the user who has the require devices and resources to operate such services. However, different challenges are reported in terms o availability and homogeneity. These challenges are mainly focused on the integration,...

Modeling the impact of non-point source pollution in catchments is a complex problem, and one that has troubled natural resource managers for many years. The development of spatially distributed hydrologic models has led to improved model forecasting at the cost of requiring more detailed spatial information. In addition, the analysis is much more sensitive to errors in the data. Incorporation ...

Observes that while most school site management personnel are familiar with the multitude of visual representations of statistical data, via graphs and charts, the value of visual representations of geographical information remains largely unknown in educational management. Explains that geographical information systems (GIS), in addition to determining the exact geographical street address loc...

Although being increasingly powerful in handling spatial data, geographical information systems (GIS) still lack the powerful functionality for process modeling in terms of simulation and optimization. This article discusses the concepts and methodologies of a geographical simulation and optimization system (GeoSOS). GeoSOS integrates cellular automata (CA), agent-based models (ABMs), and swarm...
