Map Works was started in late 1998 by Ralph Vomaske. Primary photogrammetric production is using softcopy (photogrammetric software).

Map Works has primarily been producing 1/2 to 2 foot interval contour mapping and orthophoto mosaics.

Typical workflow starts with bidding to specifications and a specific map area. Aerial flight planning and ground control are plotted to cover the project. Digital Terrain Mapping (DTM) collection or contouring are usually performed, along with planimetric mapping. Map delivery is in digital format.

In DTM collection constructed features (such as ditch, road, and sidewalk) are collected in 3D for contour interpolation. This data is also usable for orthophoto mosaic generation, delivered in TIF format.

Specifications needed for bidding include aerial photography (color or panchromatic), map scale, contour interval (vertical accuracy), and orthophoto pixel size.

Existing photography from government sources is often available for projects of larger contour interval, where less recent photo dates are acceptable. This can greatly reduce the customers cost.

Experience includes delivery of projects in metric units and for GIS base mapping.
