Web component development for satellite imagery internet service system

An Internet service system for searching and distributing satellite image maps is developed using IMS (Internet Map Server). IMS is a component solution to serve a generated gif-formatted raster map to Internet users using a pre-generated raster image and spatial data stored in ZEUS/X, the ZEUS object-relational spatial database engine. To a certain defined level, IMS generates the result raster map using a pre-generated raster image, and for a higher level, uses the spatial data stored in ZEUS/X. This hybrid method reduces disk space and map generation time. The SIIS system offers various functions for finding a location using a district name, building name, and map name. The building class is divided into subclasses, e.g. tourism, education, public, etc., to enable one to find a building not only from the detailed subclass but also from the entire building class
