| I-225 Design Survey, Aurora, Colorado

Interface with Terrestrial Lidar Aero-Metric in Fort Collins, Colorado mapped a 6-mile segment of I-225 for the Colorado DOT, Region 6, through David Evans & Associates (DEA), the land surveyors on the project. This stretch of freeway links I-70 with I-25. Recognizable detail was a key criterion, and our low-altitude flight, 1,000-feet above mean terrain, produced topographic mapping to meet stringent DEA survey requirements.

"We have received great cooperation and teamwork on this and other projects that we have done with Aero-Metric. Their work is always meticulous and thorough. On this project we incorporated Aero-Metrics’s photogrammetric mapping with our topographic data that was acquired conventionally and with high-definition terrestrial lidar scans on the bridge structures. The low-elevation photogrammetric mapping blended seamlessly with the terrestrial data to create a very accurate model." —Gary Leak, PLS, Denver Survey Manager, David Evans & Associates, Inc.
