OT Collection Name: Post Hurricane Harvey Mapping of the Mission River, Texas 2018
Short Name: TX18_Guneralp, TX18_Guneralp2C, TX18_Guneralp3C
Collection Platform: Airborne Lidar
This lidar dataset was collected as part of an NCALM Rapid Response Project for Inci Gunerlap at Texas A&M University. Data collection covers and area of ~69 km2 along the Mission River in Refugio, Texas after Hurricane Harvey.
Note: this project utilized three laser channels during its data collection. Each of the returns contained on the LAS tiles are encoded with a laser channel value. The values used are 1 (1550 nm), 2 (1064 nm), and 3 (532 nm), and are stored in the "User Data" record of the Point Data records in the LAS file.
This data collection also contains hyperspectral images that are 72 Band, 1.5 m pixel size, in PCIDSK (.PIX) format. The digital number in the PIX image corresponds to milli-SRU (spectral radiance units). One SRU is equivalent to one microwatt per square-centimeter per steradian per nanometer. Files are provided as individual flight strips as well as a single mosaic file of flight strips. These images can be downloaded here
The pre-computed Raster products are split into two separate landing pages: C1-2, and C1-2-3.
DEM from classified ground and bathymetry returns from all channels
DSM from first returns from all channels (C1C2C3)
Water surface grid from point class 39
Bathymetry grid from point class 9
