An Overview of Chiroptera Lidar and Imaging System
Chiroptera lidar system consists of two active sensors which make use of near infrared wavelength for topographic surveys, and near infrared+green wavelengths for bathymetric elevation measurement.
Imaging system consists of five passive sensors such as RGB natural color/color infrared camera, hyperspectral visible rear infrared (VNIR) and shortwave infrared (SWIR) camera, as well as broad band microwave infrared (MWIR) and longwave infrared (LWIR) camera.
Potential advantages of multi-spectral LIDAR:
- Seamless topographic-bathymetric elevation deata and images
- Sea surface/floor reflectance
- Chlorophyll/CDOM concentration
- Seafloor/landcover classification
- ARL:UT unique waveform feature extration algorithms for enhanced classification using both the visible and near-infrared wavelength
- 3-D volumetric view of water column
- 3-D auto stereo view
- Data fusion capabilities for improved geospatial analysis
An airborne suite of active and passive sensors
- Data fusion techniques and exploitation algorithms can be optimized for specific applications and environments
- Owned and operated by UT Austin's Bureau of Economic Geology
