Flood disasters are among the world's most damaging types of disaster and occur frequently in the world, which cause great personal injuries and property damages. To improve flood risk management and decision-making, a flood risk assessment spatial decision support system architecture is proposed that capitalizes on the latest advances in remote sensing, geographic information systems, hydrologic...
This paper focuses on introducing load balancing spatial analysis into XML/GML/SVG-based WebGIS. We discuss the issues of GML-based spatial data representation and analysis, and design a load balancing middleware to dispense a spatial query and analysis to the server side or the browser side based on the cost of that spatial query. Finally, this paper designs some case studies. The results of the...
This paper proposes an SVG-based spatial analysis method to support spatial query and analysis in the Web environment. We discuss two issues of this method. First, based on the theory of spatial data modeling, we propose an SVG-based spatial information representation model to represent the needed geospatial data in SVG. Furthermore, this paper designs and implements some spatial operators and integrates...
