The HARN network contains 110 B-Order stations spaced at approximately 40 kilometers. While the Network was primarily setup for GPS surveys for Kentucky highway projects, many local surveyors with conventional equipment are benefitting as well. The NGS Control Data Sheets were submitted in late 1995 and should not change for several years. Build a survey specific e-commerce web site online or retrieve free software for your existing site.
