Generating a three-dimensional physical map using different data sources

A computing device for generating a physical map using an additive manufacturing process, the computing device comprising a processing device configured to:

• receive topographic data that identifies topographic features of a geographic area, including elevational features of the geographic area, wherein the topographic data comprises digital surface model data;
• receive map area data that identifies a subset area of the geographic area;
• generate map data based on the topographic data and the map area data;
• modify the map data to generate modified map data by processing tactical imagery of at least a portion of the geographic area to correlate at least one object in the tactical imagery with a same at least one object in the digital surface model data of the topographic data, the digital surface model data corresponding to surface features of the geographic area;
• and
• converting the modified map data into a machine-readable format for generating a physical map using an additive manufacturing process, the physical map comprising a three-dimensional depiction of the topographic features of the subset area of the geographic area.
