Calgary, August 9, 2013 – High-resolution hyperspectral VNIR (Visible to Near-Infrared) mapping capability has been added to a national Philippine Lidar-based 3D mapping initiative. ITRES has delivered a hyperspectral CASI-1500 imager and provided on-site system training to ASTI (Advanced Science and Technology Institute) and the University of Philippines. This high-performance imager will provide information-rich image layers to this initiative’s terrain mapping capability.
The University of Philippines’ Disaster Risk and Exposure Assessment for Mitigation (DREAM) program was established to topographically map the country’s 22 major river basins and develop high-resolution elevation data for flood disaster mitigation modeling using Lidar.
Adding high resolution airborne hyperspectral data from the CASI to the centimetre-level topographic data derived from Lidar provides an information-rich set of image layers to augment this program’s data visualization needs. Among other capabilities of this imager, vegetation cover (land, shore, and aquatic) may be mapped and characterized in detail. A programmable imager sensitive to spectral wavelengths between 380-1050nm, the CASI-1500 provides spatial resolutions between 20cm and 1.5m. Reflected light is measured using 10’s to 100’s of sampling points to enable detailed spectral “signatures” to be analyzed.
CASI-Lidar data fusion can take three forms: 1) simultaneous data collection; 2) input of a pre-existing Lidar DEM to the CASI for orthocorrection when its optional in-flight processing system is used; or 3) 3D terrain/cover modelling and data visualization via hyperspectral drapes over Lidar data.
