ERDAS IMAGINEĮRDAS IMAGINE was demonstrated in October 1991 and released as ERDAS IMAGINE 8.0 in February 1992. at a high management level and in various products offerings into 2007. This relationship between ESRI and ERDAS, Inc. The "ERDAS-ARC/INFO Live Link" allowed the mapping community to use technology from both companies to deliver high quality image display and image processing with powerful GIS capability. The release of versions ERDAS 7.0 - 7.5 marked a period of wide acceptance of remote sensing technology among US federal and state agencies as well as research universities needing to monitor natural resource changes.Ī link between ESRI ARC/INFO and ERDAS 7.3 was introduced in 1988. In ERDAS 7.2 (Jan 1983) the first PC version of ERDAS software was licensed to the University of South Carolina Department of Geography. These systems continued to be a command prompt system, but added a nested menu assisting the customers through the prompted needed do process the imagery into data used in a GIS. This product was a movement from the more turnkey, custom design of the ERDAS 400 systems to a MS DOS IBM PC. Between 19 different versions of ERDAS 400 legacy were delivered to NASA, US Forest Service, US Environmental Protection Agency, the State of Illinois, and others. The hardware needed to make this capability available at an affordable price did not exist at the time, therefore some circuit board and other hardware designs were needed to deliver the product. This early ERDAS system was a turnkey computerized forest-management system for the state of New York system. When the hard disk was installed, ERDAS engineers had to take a cut out the back of the computer furniture to make room for the cables. It had 80 MB fixed disks and a very large 16 MB removable platter. The hard drive was a CDC-Wren about the size of a small washing machine. Later other options were added, such as a large digitizing tablet, and a hard drive (hard drives usually did not exist on computers this size). The system was built into a desk and was configured with one color monitor (256 x 256 resolution), one B&W monitor, two 8" floppy drives (one for software and one for data). The first version of ERDAS was launched in 1978 on Cromemco microcomputers based on the 8-bit Z80 CPU running the CDOS operating system. These applications exist today within the ERDAS IMAGINE Suite which has grown to support most satellites, airborne mapping cameras and digital sensors used for mapping. developed various different products to process satellite imagery from AVHRR, Landsat MSS, Landsat TM and SPOT imagery into land cover / land use maps, map deforestation, and assist in locating oil reserves. Prior to the ERDAS IMAGINE Suite, ERDAS, Inc. 1.6 ERDAS IMAGINE Softcopy Photogrammetry.Other usage examples include linear feature extraction, generation of processing chains ("spatial models" in ERDAS IMAGINE), import/export of data for a wide variety of formats, ortho-rectification, mosaicing of imagery, stereo and automatic feature extraction of map data from imagery. The level of brightness, or reflectance of light from the surfaces in the image can be helpful with vegetation analysis, prospecting for minerals etc. It is a toolbox allowing the user to perform numerous operations on an image and generate an answer to specific geographical questions.īy manipulating data placement in imagery it is possible to see features that would not normally be visible. It is aimed primarily at geospatial raster data processing and allows the user to prepare, display and enhance digital images for use in GIS or in CAD software. ( January 2009)ĮRDAS IMAGINE is a raster graphics editor and remote sensing application designed by ERDAS, Inc. If notability cannot be established, the article is likely to be merged or deleted.
