Sensor Model Support

SOCET GXP® utilizes the metadata associated with imagery in order to accurately georeference pixels to real-world ground coordinates. Metadata may be embedded in the image data directly or included in supplemental files associated with the pixel data. While SOCET GXP support several simple planimetric sensor models such as four corner, the full power and accuracy of SOCET GXP is realized when a projective model can be initialized. A projective sensor model is often referred to as a rigorous sensor model and relates line and sample image coordinates to full 3D ground coordinates. When a rigorous sensor model is available, users can run the full suite of photogrammetric capabilities included in SOCET GXP such as triangulation, stereo viewing and mensuration, automatic terrain extraction, height mensuration, orthophoto generation, and much more.

GXP has established close ties with the Community Sensor Model (CSM) working group, government agencies, programs, system integrators, satellite operators, and airborne camera providers. SOCET GXP engineers have decades of experience in complex photogrammetric techniques and sensor model development that allow for rigorous sensor models to be created across a multitude of sensors. When multiple sensor models can be initialized from a particular image, SOCET GXP allows users to pick the model most relevant for their needs. As new satellites and airborne sensors become available, GXP continuously updates SOCET GXP to ensure they can be utilized and will provide the highest degree of accuracy possible.
