Spatial Information Retrieving Using Internet

The primary view of geographic data has historically been through maps. Now, rise of 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 use of 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 visualization and integration of spatial data. This study represents an access to earthquake information and interactive database applications with querying capabilities over Internet. In this study, data acquired from different sources were compiled by using GIS softwares. WebGIS software packages provide various kinds of GIS functions and analysis. This study has implemented with MapObjects Map Server.
