Dynamic Web Map Service for Web Publishing System of Mass Remote Sensing Images

This Dynamic web map service, a key technique in systematical structures of Internet mapping, is presented in implementing web publishing system of mass remote sensing images. Dynamic web map service enhances the flexibility of establishing various online map services. Dynamic web map service provides a powerful Internet mapping solution, with the ability to present, link, distribute and publish geomatics-based data and services. And it also provides the infrastructure to access spatial information from disparate data sources and to display the information in powerful, easy-to-use web mapping applications. Appropriate system framework and software platforms are adopted in order to establish stable website and create web map service for publishing mass remote sensing images on Internet. Due to the excellent RDBMS such as Oracle, and WebGIS software platform and spatial data engine such as ArcIMS and ArcSDE, web publication system of mass remote sensing images could be implemented. Dynamic web map service implemented functions of interactive map, online editing and mass remote sensing image information browsing in real time. These applications extend the power of geographic and descriptive data presentation, providing the most flexible web publishing solution. Dynamic web map service, together with dynamic database connection, provides mass remote sensing images' Internet mapping efficiently and effectively. A practical application of publishing earthquake information data on Internet is fully illustrated.
