The ImageStation Satellite Triangulation Modules are built on top of the
ImageStation Digital Mensuration (ISDM) product, which provides a powerful
multi-image point transfer and measurement environment for any type of digital
imagery. Ephemeris data and sophisticated orbital models are used to triangulate
SPOT, IRS, QuickBird, and Landsat imagery (IKONOS is available directly in
ImageStation Digital Mensuration).
These products represent the triangulation portion of digital satellite
workflows. Other ImageStation products are used for 3D feature/DTM exploitation
and orthorectifucation.
Why are the ImageStation Satellite Triangulation Modules right for your
workflow?
- A rigorous orbital model provides accurate results with a minimal number of
ground control points
- An accurate relative solution is possible with just tie points
- A robust method for adjusting the time-dependent exterior orientation
parameters of the satellite imagery is performed through an independent
weighting of sensor parameters, image point coordinates, control point
coordinates, and tie points
- Orbital constraints permit cantilevering and bridging capabilities
