GEOGRAPHICAL DATABASE CONSTRUCTION METHOD

摘要

A geographical database construction method is provided. The method includes: on the basis of the sizes of geographical grids covered by authorized users, the largest theoretical power value of each grid is obtained through calculation; according to application limits of cognitive devices, the largest actually-usable power value used in each geographical grid is obtained and replaces the largest theoretical power value; the geographical grids same in largest actually-usable power value are integrated into a smallest number of rectangular areas, new geographic coordinates are constructed for the rectangular areas, and a geographical database is constructed by combining the largest actually-usable power values. The geographical database where the uneven size geographical grids small in data amount and small in calculation amount are stored is obtained with the present invention.
