GENERATION OF HIGH RESOLUTION POPULATION DENSITY DATA SETS THROUGH EXPLOITATION OF HIGH RESOLUTION OVERHEAD IMAGERY DATA AND LOW RESOLUTION POPULATION DENSITY DATA SETS

摘要

Utilities (e.g., systems, methods, etc.) for automatically generating high resolution population density estimation data sets through manipulation of low resolution population density estimation data sets with high resolution overhead imagery data (e.g., such as overhead imagery data acquired by satellites, aircrafts, etc. of celestial bodies). Stated differently, the present utilities make use of high resolution overhead imagery data to determine how to distribute the population density of a large, low resolution cell (e.g., 1000 m) among a plurality of smaller, high resolution cells (e.g., 100 m) within the larger cell.

1. A method for use in generating population density data sets of a geographic region from overhead imagery data, comprising:
identifying areas of built-up structures in at least one input overhead image of a geographic region; obtaining population density estimates of a plurality of first portions of the geographic region; and with a processor, using the areas of built-up structures in the at least one input overhead image within the first portions to allocate the population density estimates across a plurality of second portions within the first portions.
