Claim One:
1. Method of processing camera data of a mobile mapping system, the method comprising: obtaining camera data from at least one camera of the mobile mapping system when traveling along a road; obtaining range sensor data from at least a first range sensor, the range sensor data at least partially corresponding to the camera data; detecting at least two regions in the camera data, the detecting comprising detecting, within a predetermined area, regions having a first specified shape and regions having a second specified shape; assigning a level of interest to each of the at least two regions, the assigning comprising assigning the regions having the first specified shape a first level of interest, assigning the regions having the second specified shape a second level of interest, and assigning regions outside the predetermined area a third level of interest; and applying a compression technique on the camera data in the at least two regions based on the assigned level of interest for each region, wherein applying the compression technique comprises reducing the color space of one of the at least two regions to a constrained color space, the constrained color space including only colors that are used on human-made objects of the corresponding specified shape.
