Description zzzzzzzzzzzzzzz We are currently in the first year of another five-year contract to update 100% of the City’s orthoimagery and 20% of the mapping annually. We used the DMC digital mapping camera to acquire color digital orthophotos at 1”=100’ with 0.5’ ground pixel resolution. Fully analytical aerial triangulation met all requirements to produce 1”=100’ mapping. Surdex updated the 2’ DTM and contours, and produced 1,037 tiles of digital orthophotography. Surdex provided a project-wide map that denoted the areas of change as compared to the previous project. Surdex also updated 2’ contours and DTM.
