While the old business model centered on increasing the number of sensors in a system, the new business model is centered on the use of satellite imagery to improve the spatial information within an enterprise’s geospatial database, or GDB. The satellite-borne sensors, such as , the Airborne Imaging Spectro-Radiometer (AIRS) and the Airborne Hyper-Spectral Radiometer (AHSR), can collect more than 16 terabytes of data at a rate of up to 60 gigabytes per second. When integrated into an enterprise’s GDB, new spatial information can be obtained in a manner that improves the accuracy of modeling and analysis for disaster recovery, asset inventory, site monitoring, infrastructure management, environment monitoring, and other activities.
ERDAS® IMAGINE 2018 uses spatial modeling tools to support the integration of the various satellite imagery sources, such as Geoeye Global Navigation Satellite System (GNSS), MODIS, AERONET, Landsat, and Quickbird, and it enhances the visualization of the data.
