Projecting Lower-Geographic-Resolution Data onto Higher-Geographic-Resolution Areas

摘要

Provided is a process of augmenting a geographic information system by projecting lower-geographic-resolution data on to higher-geographic-resolution areas, the process including: obtaining aggregate values each describing an attribute of different coarser geographic areas; obtaining a geographic-information system (GIS) having records each describing attributes of a finer-grained geographic area; identifying, for each of the coarser geographic areas, corresponding finer-grained geographic areas of the GIS; projecting, for each of the coarser geographic areas, the aggregate value of the respective coarser geographic area unevenly onto the corresponding finer-grained geographic areas based on respective attribute values of the corresponding finer-grained geographic areas; and storing in memory of the GIS.
