Dioptra has completed a control survey for the North Bannock County Area/City Impact Area covering 19 sections in 2 townships. This included obtaining accurate Latitude and Longitude positions on all corners, establishing reference monuments to corners that are in heavy traffic areas, and recording new corner perpetuation records for all corners. This project was completed using both Static and RTK GPS. Baselines were run from the IDPO CORS station and verified by local NGS monumentation. A low distortion coordinate system was established for use by all other consultants and agencies using GPS.
