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 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|
