ABSTRACT:
The Internet has been changing the access and transmission of GIS data, applications and visualizations. Online GIS combines the
advantages of both GIS and the Internet. Geographic information can be distributed in a variety of forms on the Internet. Moreover
as the Internet technology takes progress, web-based GIS applications also change. This paper focuses on development and
implementation of a web-based GIS application for earthquake information. In this study, a dynamic map browser type of webmapping
applications was designed for interacting with the earthquake information. This method provides users easy access to GIS
data and basic functions on the Internet with low technological requirements. The user is not required to learn anything beyond the
basics about how to interact with the system as well. In the study, a GIS application and a web site was developed to serve the system
on the Internet. By integrating various data from different sources, this study aims to provide public users can access information
about earthquakes doing spatial and attribute query. Furthermore this model enables easy data management including maintenance
and updating.
