The NBCD2000 project, funded by NASA's Terrestrial Ecology Program, combines vegetation canopy heights derived from digital elevation data collected during the 2000 SRTM. The mission mapped 80 percent of the Earth's land mass with a radar instrument, producing the most complete digital surface map of Earth. In combination with the National Land Cover Database (NLCD) and National Elevation Datasets (NED), a high-resolution database of circa-2000 vegetation canopy heights, aboveground biomass, and carbon stocks for the continental United States is generated, providing an unprecedented base line against which to compare data products from the next generation of advanced Earth observing, remote sensing platforms.
"PCI Geomatics is pleased to donate Geomatica to the NBCD2000 project, as it proves to be the foundation for future studies. Carbon stock data sets are vital to determining the impact on climate change from both natural and man-made occurring events," says Cary Lichtman, an account executive at PCI Geomatics. "Geomatica's ability to handle large quantities of high-resolution, multi-formatted data efficiently and accurately is ideal for this ground-breaking research."
Geomatica will be used for the integration and visualization of raster data sets in various formats through our Generic Database (GDB) technology in Geomatica Focus. Geomatica OrthoEngine will streamline the processes of data mosaicking and reprojection. The advanced Geomatica image analysis and modeling tools are at the core of building the raster data processing models to generate the final data sets. Given the national scope of the project, PCI technology is well-suited to handle batch processing requirements through the EASI programming environment.
"The National Biomass and Carbon Dataset 2000 project is based on the integration of large multi-source data sets, including radar and optical satellite data, and thematic GIS layers," says Dr. Josef Kellndorfer, an associate scientist with the Woods Hole Research Center. "PCI Geomatica technology is instrumental to support the data integration of these large continental-scale data sets with respect to cartographic data set reprojection and data resampling, and also provides the scientific analysis tools to deal with the data fusion and analysis aspects of the various data resources. Geomatica software allows for efficient handling of such complex tasks."
