Figure 1. GeoMiler System Flow
Figure 1 shows the three GeoMiler components – data processor, route solver, and map interface. The data pre-processor hosts all the input survey data received from the Census Bureau, and the post-processor returns the output data to the Census Bureau. The route solver performs the mileage calculations for all the freight modes. The mapping interface allows visualization of routes for any shipment records that have problematic input data and allows shipment paths to be checked, verified, and corrected.
