Smart Data algorithms process original imagery data, so only one set of imagery is required. In all cases, only the original imagery was processed - no intermediate disk files were created or needed. A normal view of Landsat TM over San Diego, as would be seen from space. The same image, enhanced using different wavelengths of light to show vegetation in red. This time the Landsat imagery has been processed to show all areas of water in light blue.
Red areas facing north-east are higher fire risk.
All of these views were created from the same imagery files, using ER Mapper Smart Data algorithms. ER Viewer will display a 3D algorithm in 2D Vector overlays in algorithms will not be displayed in ER Viewer. ER Mapper can process and view Smart Data algorithms without these restrictions.
