Colors for the maps were selected with the assistance of ColorBrewer, an online tool for selecting map color schemes. The software also executed other cartographic functions, including: assigning symbology to represent the data randomly placing dots creating and positioning map titles, legends and notes and outputting individual maps to digital image files.
The customized software performed statistical calculations to allocate the number of dots for a geographic area. The system utilized agricultural statistical data files, geographic area boundary files, land use/cover boundary files, map parameter data files, and customized GIS and statistical software to produce thematic dot-density maps. NASS developed an automated map production system to generate digital map files based on statistical data from the 2017 Census of Agriculture. Geographic information system (GIS) and desktop publishing technologies were used in the production of these thematic maps.
