The accuracy achieved on GCP.s: RMS X = 2.2 m, RMS Y = 2.3 m, RMS Z = 1.1 m; and on independent check points (ICP.s) RMS X = 5.0 m, RMS Y = 2.9 m, RMS Z = 4.7 m. DTM has been generated automatically with the use of MATCH-T Inpho software and filtered with in-house software. DTM prepared on the basis of SPOT stereo data has been checked against reference data - DTM generated from aerial photographs in scale 1:26 000. The accuracy of DTM generated with SPOT 5 HRS within the HRS Scientific Assessment program (HRS-SAP) of ISPRS and CNES on site 9 Chiemsee (Germany) is also presented. Geomatica OrthoEngine of PCI has been used for orientation and DTM generation.
