IMAGINE Photogrammetry explained

IMAGINE Photogrammetry (formerly Leica Photogrammetry Suite – LPS) is a software application for performing photogrammetric operations on imagery and extracting information from imagery. IMAGINE Photogrammetry is significant because it is a leading commercial photogrammetry application that is used by numerous national mapping agencies, regional mapping authorities, various DOTs,[1] as well as commercial mapping firms. Aside from commercial and government applications, IMAGINE Photogrammetry is widely used in academic research. Research areas include landslide monitoring,[2] cultural heritage studies,[3] and more.

Capabilities

IMAGINE Photogrammetry is generally used for the processing of raw imagery through to the creation of geospatial data products such as digital terrain models, 3D features, and 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 triangulated, image pairs may be viewed in stereo and 3D measurements can be made. The system can automatically generate digital terrain models, which can be reviewed and edited in stereo. Once an accurate 3D surface has been derived, triangulated images may be 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:

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:
