Ground control will be supplemented by Airborne Global Positioning/Inertial Measurement Unit or AGPS/IMU solution and processing techniques. In order to ensure consistency with past projects, horizontal and vertical control for the aerial survey and derivative products was based on the existing High Accuracy Reference Network (HARN). The two stations used were SANTAIR FO1673 and MORIAIR 2 EQ1151 with the most up to date NGS values for these stations.
New control and photo identification was added as needed which was determined by the project geospatial analyst and LiDAR acquisition team
Process_Step:
Process_Description:
Project control specifications were processed in units of US Survey Feet; horizontal datum – NAD83(92); vertical datum – NAVD88; projection – Transverse Mercator; State Plane New Mexico Central Zone (3002); basis of bearing – Grid Bearings.
For the absolute sensor calibration of the LiDAR, adjustments were performed for the difference in roll, pitch, heading, and scale between the raw laser point cloud from the sensor and surveyed control points on the ground.
The absolute accuracy assessment performed comparative test results that showed elevation differences between each static survey point and the laser point surface.
Field Methodology: OPUS static, fast static, RTK, published control values.
Equipment used: Trimble GPS equipment (R8 dual frequency receivers).
