ABSTRACT:
A method of converting a geospatial database into a compressive database for multiple dimensional data storage by constructing computer storage data language or format includes the steps of partitioning the geospatial database into a plurality of data segments; selecting a specific point position in each of the data segments as a reference point position (RPP), and then forming a set of reference point positions for the original geospatial database; providing a coordinate origin point for each of the data segments; converting the geodetic coordinates of the original geospatial database within each of the data segments into corresponding local coordinates, and converting the set of reference point positions and the local geodetic coordinates of each of the data segments into pixel coordinates in form of a pixel coordinate system to form a specific digital map database.
