Dataset Identification:
- LIDAR-derived binary (.las) files containing points classified as bare-earth and canopy (first return) were produced for the 2007/2008 Northwest Florida Water Management District - 5 Counties (Calhoun, Holmes, Washington, Jackson and Liberty), Florida lidar mapping project. The files were provided in a scheme of FDEM-derived 5,000 x 5,000 foot (1500 x 1500 meter) tiles. When initially processed, horizontal mapping units were in UTM meters, vertical mapping units are in U.S. survey feet. The total mapping area covers approximately 2102 square miles.

- name Of Measure Horizontal Positional Accuracy Report
- evaluation Method Description Horizontal accuracy is verified in three tests. During bore sighting, adjoining flight lines are view in profile and hard edged features are observed and if necessary the flight lines are adjusted for good relative horizontal and vertical fit. The second test for horizontal accuracy is by comparing raw contours from each flight line against adjoining flight lines at specific points. The final test is the vertical LIDAR control report.
- name Of Measure Vertical Positional Accuracy Report
- evaluation Method Description Survey control points were used to validate the accuracy of the LIDAR surface model after automatic and hand filtering. This surface exceeds the NSSDA vertical accuracy specifications of 1.2 ft.
- name Of Measure Vertical Positional Accuracy
- measure Description This value is measured as RMSEz.

-
- evaluation Method Description This dataset contains classified returns of the LIDAR sensor. The sensor data was verified in MARS software to ensure complete coverage.
- measure Description Calibrations of the LIDAR flight line data are performed; this process is known as bore sighting. The flight lines are compared to evaluate both their relative and absolute accuracies.
- name Of Measure Quantitative Attribute Accuracy Assessment
- measure Description n/a
- evaluation Method Description Verification of attribute accuracy of LIDAR data involves the use of filtering techniques. Auto-filtering uses algorithms to reclassify data in the point cloud. Hand-filtering involves the use of a technician working in a graphic environment to reclassify the erroneous points that may remain in the LIDAR point cloud after auto filter.
