Spatial Information Retrieving Using Internet

The primary view of geographic data has historically been through maps. Now, the rise of the Internet has allowed to provide geospatial data through online mapping interfaces. A Geographic Information System (GIS) is an organized collection of computer hardware, software, geographic data, and personnel designed to efficiently capture, store, update, manipulate, analyze, and display many forms of geographically referenced information (ESRI 1995). Together with the use of the Web, GIS allows public to access GIS functions and data. WebGIS is described as a network-centric tool that uses "the Internet" to access and transmit data and "analysis tools" to enhance the visualization and integration of spatial data. This study represents an access to earthquake information and interactive database applications with querying capabilities over the Internet. In this study, data acquired from different sources were compiled by using GIS softwares. WebGIS software packages provide the various kinds of GIS functions and analysis. This study has implemented with the MapObjects Internet Map Server.
