This dataset is the bare earth lidar data for St. Johns County, Florida, acquired in early January and February of 2004. This
data was collected to develop comprehensive countywide base mapping and perform other GIS enhancements to support master drainage
planning, transportation planning, preliminary engineering and wetland preservation studies. The surveyed area included all
of St. Johns County, approximately 610 square miles. Eighty-seven (87) flight lines of high density lidar data (average GSD
is 3.3 feet) were obtained at an altitude of 3000 feet AGL. This data set contains only model keypoints (points that are a
thinned data set that is intended to remove extraneous data such as trees and points that are deemed redundant to the final
bare earth product) that are classified as ground points. As a result, there are a lower number of points than in a full mass
point lidar data set; and it is recommended that the data be downloaded as points and used with a TIN (Triangulated Irregular
Network) or similar algorithm to produce a bare earth surface.

purpose:
The purpose of this topographic lidar survey was to produce a digital terrain model (DTM) of sufficient density and accuracy
to generate 1-foot contours, compile limited planimetric features and generate panchromatic (black and white) digital orthophoto
imagery (DOI).

Use limitation statement:
These data depict the elevations at the time of the survey and are only accurate for that time. 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temporal changes may have occurred since this data set was collected and some parts of this data may no longer represent actual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.
Any conclusions drawn from analysis of this information are not the responsibility of NOAA or any of its partners. These data

Use Limitation
While every effort has been made to ensure that these data are accurate and reliable within the limits of the current state
of the art, NOAA cannot assume liability for any damages caused by any errors or omissions in the data, nor as a result of
the failure of the data to function on a particular system. NOAA makes no warranty, expressed or implied, nor does the fact
of distribution constitute such a warranty.
