2001 SRWMD BE Lidar: Alachua County (FL)

This is a point dataset of elevations over the NE quadrant of the Mikesville quadrangle, Florida. The data were derived from LIDAR measurements performed in 2001. The data are 'edited' to the extent that they have been reduced to a 'bare ground' representation; most above ground level features and objects such as buildings and trees have been removed from these data.

Delivered points as unclassified bare-earth processed points. NOAA OCM reclassed all points to the Ground class

These data are used for the production of Triangulated Irregular Network (TIN) digital elevation models or whenever a direct representation of the bare-earth LIDAR point data is needed.

Users should be aware that temporal changes may have occurred since this data set was collected and some parts of this data may no longer represent actual surface conditions. Users should not use this data for critical applications without a full awareness of its limitations. These data depict the heights at the time of the survey and are only accurate for that time.

The Fundamental Vertical Accuracy (FVA) of the Classified Bare Earth files for the project area achieved an RMSE of 0.057 meters. One-hundred and Five (105) 'open terrain' survey control points were used in this evaluation, with an additional 20 'open terrain' points held in reserve and supplied to the client.

Data products collected were acquired at manufacturers system specifications, with a nominal point spacing of 0.68 meters.; Quantitative Value: 0.30 meters, Test that produced the value: Acquired at or below 1500 meters above mean terrain (AMT) and have a horizontal accuracy of 0.30 meters (per manufacturers system specifications)

The Fundamental Vertical Accuracy (FVA) of the Classified Bare Earth for all Areas achieved is 0.057 meters at a 95% confidence level in the "Open Terrain" land cover category. One-hundred and Five (105) survey control points were used in this evaluation.; Quantitative Value: 0.057 meters, Test that produced the value: FVA of the classified bare-earth points
