Data quality information
Scope of quality information
- name Of Measure Horizontal Positional Accuracy Report
- evaluation Method Description Horizontal positional accuracy for LiDAR is dependent upon the quality of the GPS/INS solution, sensor calibration and ground conditions at the time of data capture. Standard horizontal accuracy for LiDAR at this mapping scale is 1 meter (3.28').
- name Of Measure Horizontal Positional Accuracy
- measure Description This value (in meters) is computed by comparing controls to an intensity based image derived from the classified LiDAR data and represents the RMSE of residuals on controls within the project area.
- Quantitative Result
-
- result value 1.0
- value Units
-
- name Of Measure Vertical Positional Accuracy Report
- evaluation Method Description Horizontal positional accuracy for LiDAR is dependent upon the quality of the GPS/INS solution, sensor calibration and ground conditions at the time of data capture. The vertical accuracy was tested with a result of a RMSE 0.062m (0.205').
- name Of Measure Vertical Positional Accuracy
- measure Description This value (in meters) is computed by comparing controls to the classified LiDAR ground surface and represents the RMSE of residuals on controls within the project area.
- Quantitative Result
-
- result value 0.062
- value Units
-
- evaluation Method Description LiDAR data is collected within the project area, processed and verified against control. The bare earth surface will contain voids where insufficient energy was reflected from the surface to generate a valid return from the terrain.
- measure Description Data was filtered using automated procedures followed by a manual review of the completed data set.
