Southeast Asia Geo-Spatial Data Center Project

The Geo-Spatial Digital Archive Project aims to establish an online data service center for geo-spatial information in Southeast Asia. Users can access data via text, geo-location, or metadata search methods for various studies. The project addresses the lack of public access to digital archive data in Thailand and provides applications for history, archaeology, urban studies, and land use/cover studies.

  3. Objective • Establish the South-East Asia Geospatial information center. • Produce a demonstration system of online geo-spatial data service • User can search and access the data through various methods: text search, geo-location search, and meta-data search. • The applications of the data will be for any studies that can utilize these data sets

  4. A demonstration system of online geo-spatial data service that user can search and access the data Overview of GDAPGeo-Spatial Digital Archive Project through various methods: text search, geo-location search, and meta-data search. The applications of the data will be for any studies that can utilize these data sets.

  5. Motivation • Availability of • Data: digital data via remote sensors, aerial photos, vector, 3D, public maps • Communication: internet, multimedia • Tools/Software • Cheaper hardware: computers, storage, digital cam, camcorder
