== Capabilities ==
IMAGINE Photogrammetry is generally used for the processing of raw imagery through to the creation of geospatial data products such as [[digital elevation model|digital terrain models]], 3D features, and [[orthophoto|digital orthophotos]]. There are a number of approaches for photogrammetric applications. Imagery may come from [[remote sensing]] satellites, airborne cameras (film or digital), or ground-based cameras. In the context of airborne film cameras, the workflow would involve scanning the imagery (creating a digital version of the film imagery), solving the interior orientation parameters, and triangulating the images. Once the images are [[triangulation|triangulated]], image pairs may be viewed in stereo and 3D measurements can be made. The system can automatically generate [[digital elevation model|digital terrain models]], which can be reviewed and edited in stereo. Once an accurate 3D surface has been derived, triangulated images may be [[Orthorectification#Orthophoto_Process|orthorectified]]. In addition to this workflow, IMAGINE Photogrammetry supports 3D feature extraction, radiometric adjustment, and a number of additional digital image processing capabilities available from [[ERDAS IMAGINE]], which is included with IMAGINE Photogrammetry.
== Other workflows ==
In addition to the workflows above, IMAGINE Photogrammetry also supports the following applications:
* Satellite Photogrammetry * Direct Georeferencing: ground control points (GCPs) are not used because the aircraft is equipped with Airborne [[GPS]] and IMU systems. This is an emerging workflow that is suitable for remote area mapping. * Close-Range Photogrammetry
== History ==
While the initial release of IMAGINE Photogrammetry (called "Leica Photogrammetry Suite 8.7") was in late 2003, it was a combination of new technology as well as software previously developed by ERDAS (which was acquired by [[Leica Geosystems]] in 2003). The product evolution is as follows:
* 1991 - "Digital Ortho" in ERDAS 7.5 * 1993 - OrthoMAX * 1994 - Warptool & Mosaictool in IMAGINE 8.2 * 1999 - OrthoBASE first release in IMAGINE 8.3.1 * 2000 - Stereo Analyst 1.0 (module for stereo feature extraction) * 2001 - OrthoBASE Pro (module for automated terrain extraction) * 2003 - Leica Photogrammetry Suite 8.7",<ref>Wang et al.
