The Texas East LiDAR Project 

The LiDAR survey of Texas East was completed between December 29, 2016 and May 30, 2018.  The Texas Water Development Board requested the survey, but other stakeholders were involved including the Texas Natural Resources Information System (TNRIS) and Texas Commission of
Environmental Quality (TCEQ).

LiDAR Data Collection

The LiDAR survey was carried out by Fugro and included a total of 3,501 square miles. The major locations in the survey included Greenville and San Jacinto County. The survey was carried out to the USGS Lidar Base Specification 1.2 quality level 2.

LiDAR Data Accuracy 

AECOM was hired by the Texas Water Development Board to provide QA/QC on the collected data.  They tested non-vegetated and vegetated vertical accuracy and have reported their findings in this report.  The table below shows the vertical accuracy findings (at a 95% confidence level).

Location Non-vegetated vertical accuracy Vegetated vertical accuracy
San Jacinto 9.3 cm / 3.7 in 12.2 cm / 4.8 in
Sulphur UTM Zone 15 9.7 cm / 3.8 in 9.5 cm / 3.7 in
Sulphur UTM Zone 14 6.6 cm / 2.6 in 9.5 cm / 3.7 in
