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.

1. A method of augmenting a geographic information system by projecting lower-geographic-resolution data on to higher-geographic-resolution areas, the method comprising:
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, wherein a plurality of the finer-grained geographic areas are in each of the coarser geographic areas; identifying, for each of the coarser geographic areas, corresponding finer-grained geographic areas of the GIS that are in the respective coarser geographic area; 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, for each of the corresponding finer-grained geographic areas of each of the coarser geographic areas, the respective projected value in association with the respective finer-grained geographic area, wherein the respective projected values have different values in the different corresponding finer-grained geographic areas of a given coarser geographic area.
