4 Digital/Softcopy photogrammetry Softcopy photogrammetry is based on digital (softcopy) raster image as distinct from conventional photogrammetry, based on film (hardcopy) images Digital systems are considered third generation photogrammetric instruments (workstation-Digital image Analytical Plotter -DiAP), after analytical (second generation) and analog (first generation) stereo-plotters Equipment used in digital photogrammetry include Computer, Scanner, CCD cameras, LCD Eyewear (stereo viewing) Orthophoto and Digital Elevation Model (DEM) can be generated from Softcopy photogrammetry
