The Horizontal Control NetworkArapahoe County has been establishing a Horizontal Control Network within the county for the past 15 years. To date we have completed 13 projects that include the eastern 42 miles of the county and the majority of the urban area. A fourteenth project, in the Watkins area, is currently underway.
Purpose of Horizontal ControlThe purpose of these projects is to obtain precise geodetic information on section and quarter section corners of the Public Land Survey System, and the resulting bearings and distances between the corners, for use by the Mapping and Land Surveying communities.
Please read the cover sheet of each individual project for the methodology and accuracy standards for the project. Full survey reports for each individual project are on file in the offices of the Mapping Section.
