LiDAR Data Accuracy 

Following the completion of the LIDAR survey, AECOM was retained to perform quality assurance and quality control (QA/QC) for the project.  Their complete findings are summarized in this report.  A summary of tested non-vegetated vertical accuracy (NVA) and vegetated vertical accuracy (VVA) at a 95% confidence level is included in the table below.

Location NVA VVA
San Antonio 6.2 cm / 2.4 in 6.5 cm / 2.6 in
La Grange 11.2 cm / 4.4 in 10.8 cm / 4.3 in
