Sand Creek Topography (Colorado Springs, Colorado)

This project was contracted through Ayers Associates, who selected the Clark Land Surveying / Aerial Mapping Services team to map a portion of Sand Creek for the City of Colorado Springs. The project consisted of establishing a horizontal and vertical control network along this 6.8 mile mapping project.

Tasks included establishing photogrammetry panel points, field survey of obscured areas and locating utilities throughout the project area. Having the project within such a large area presented a challenge to ensure the panel points were not disturbed prior to the flight.

Due to the time of year the contract was let, Clark Land Surveying had to monitor snow cover on a daily basis and coordinate with Aerial Mapping Services to ensure that when the conditions were right for flying, the targets were in place and the project area was free from snow.

Clark staff reviewed the resulting map and added improvements such as manholes, culverts and other improvements not visible in the aerial photographs, as well as performing quality control checks in the field.
