The Subject

The purpose of this study is to investigate the effective indexes of damage to a building, with the aim of reducing the possible events caused by the earthquake and presenting a model based on spatial information systems. So, after collecting the data and information required by field method and statistical blocks, a spatial database was obtained. Then, the effectiveness of each of the criteria was based on the creation of a binary comparison matrix and questioning experts from the subject The study was obtained. In the end, in order to establish a link between the influential factors and the estimation of the final vulnerability of each building, a formula was presented in which all the effective factors were involved with the emphasis on the level of effectiveness of each building. Using expert selection software, the indexes were evaluated in terms of weight and value. Finally, the geospatial information system of GIS evaluated the magnitude and severity of the earthquake in different ranges and its consequences in terms of the indices studied for the buildings in the study area.

Algorithm Implementation

Among the main issues in the theory of geometric grids on spatial information systems, is the problem of finding the shortest path routing between two points. In this paper tried to using the graph theory and A* algorithms in transport management, the optimal method to find the shortest path with shortest time condition to be reviewed. In order to construct a graph that consists of a network of pathways and modelling of physical and phasing area, the shortest path routes, elected with the use of the algorithm is modified A*.At of the proposed method node selection Examining angle nodes the desired destination node and the next node is done. The advantage of this method is that due to the elimination of some routes, time of route calculation is reduced.

New Geography

The emergence of technological systems with computerized cartographic application allowed the resolution of certain military problems between the 1950s and 1960s. The first GIS was created in Canada Geographic Information Systems in 1964 for Tomlinson. At this time, GIS was in a consolidation phase in multiple areas and for various purposes. The geographical science growth with the development of GIS were in connection to the subject of the new geography, justified by the application of the methods of quantitative analysis in various spatial nature of research. In this context, the GIS feature a number of operational advantages and have allowed the proliferation of new fields of endeavor in open access systems across multiple forms of acquisition, management, interpretation, and spatial information analysis. The main goal of this chapter is to underwrite the concept of GIS, as well as distinguish the diversity of applications from the past until the present, and to identify new paths to accommodate recent scientific approaches with extensive range of application possibilities.

Geospatial Web Services

As Web service technologies mature in recent years, a growing number of geospatial Web services designed to interoperate spatial information over the network have emerged. Geospatial Web services are changing the way in which spatial information systems and applications are designed, developed and deployed. This chapter introduces all aspects of geospatial Web services from service-oriented architecture to service implementation. It covers the life cycle of geospatial Web services in terms of geospatial interoperable standards, including publish, discovery, invocation and orchestration. To make geospatial Web services more intelligent, semantic issues about geospatial data and services are discussed here. Furthermore, the applications of standard-compliant geospatial Web service are also reviewed.
