Abstract:

This study reviews investigation for the partitioning of large spatial databases undertaken in the development of the Defense Mapping Agencys new vector product the Digital Chart of the world DCW. The DCW is a geo- spatial, topologically structured, global database designed for the use in Geographic Information Systems GIS. The study covers the characteristics of tiling, or partitioning, of large digital geo-spatial databases to improve data storage, access, and use. It identifies tiling requirements and goals for the DCW and summarizes project experience. It is the first of two reports performed under DCW development effort. The second is the Final Tile Design Study for the Digital Chart of the World, November 1990.
