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.
