OPKBundleSAT is the software for the satellite imagery RPC model refinement.
It can manage all the imagery from the main satellites (Ikonos, QuickBird, GeoEye, SPOT, Deimos, Kompsat, etc..).
OPKBundleSAT allows to work with single or multiple imagery. The RPC refinement process makes use of Tie Points and/or Ground Control Points. Tie Points searching process is fully automatic and/or manual (assisted). Regarding the Ground Control Points, user can import them as known coordinates, or can locate them using orthophotos and DEMs (Digital Elevation Model).
OPKBundleSAT also manage Check Points in order to check the accuracy of the results.
