Erdas Imagine
ERDAS IMAGINE is a remote sensing application with raster graphics editor abilities designed by ERDAS for geospatial applications. The latest version is 2015. ERDAS IMAGINE is aimed primarily at geospatial raster data processing and allows the user to prepare, display and enhance digital images for mapping use in geographic information system (GIS) or in computer-aided design (CAD) software. It is a toolbox allowing the user to perform numerous operations on an image and generate an answer to specific geographical questions.
By manipulating imagery data values and positions, it is possible to see features that would not normally be visible and to locate geo-positions of features that would otherwise be graphical. The level of brightness, or reflectance of light from the surfaces in the image can be helpful with vegetation analysis, prospecting for minerals etc. Other usage examples include linear feature extraction, generation of processing work flows ("spatial models" in ERDAS IMAGINE), import/export of data for a wide variety of formats, orthorectification, mosaicking of imagery, stereo and automatic feature extraction of map data from imagery.
==Product history==
Before the ERDAS IMAGINE Suite, ERDAS, Inc. developed various products to process satellite imagery from AVHRR, Landsat MSS and TM, and Spot Image into land cover, land use maps, map deforestation, and assist in locating oil reserves under the product name ERDAS. These older ERDAS applications were rewritten from FORTRAN to C and C++ and exist today within the ERDAS IMAGINE Suite which has grown to support most optical and radar mapping satellites, airborne mapping cameras and digital sensors used for mapping.〔Field Guide Blog (April 15, 2009).
