The document discusses a transportation design photogrammetry project completed by Continental Mapping in 2013 in Indianapolis, Indiana. 5 miles of roadway were slated for improvements including widening lanes and bridges. Continental Mapping was tasked to provide high accuracy aerial mapping data at 1"=20' scale with 0.10-foot vertical accuracy on hard surfaces to support the final design. Imagery was captured via airplane at 4 cm resolution and Continental Mapping delivered the detailed mapping and orthophotography to meet the engineer's needs on schedule.

Suburban expansion and development puts additional stresses on local
roads that exceed their design capacity. The suburban communities of
Indianapolis are no different. For this project, 5 miles of roadway were
slated for improvements including: widening threw-lanes, adding pass-
ing lanes and/or turn-lanes near intersections, widening existing shoul-
ders, and replacing/upgrading the bridges and culverts.
The design firm needed veritable high accuracy data upon which to
perform their final design, which included: 1”=20’ scale planimetric
mapping with a vertical accuracy of 0.10-foot on hard services, 1-foot
contours, and 3-inch resolution color digital orthophotography.
Continental Mapping acquired the imagery and completed the map-
ping and imagery products to meet the engineer’s needs. Imagery
was captured via airplane outfitted with airborne GPS at 4 cm ground
sample distance (GSD) along the entire 215 acre corridor.
