‚used: * Figure 3. Ikonos RMSEy,y versus image view angle, for different sites. The additional attached information concerns: 
for 1* X axis: applied model (R — RPC, P — parametric), number of GCPs used for the orthorectification, * GPS measured GCPs, 
for 2" X axis: (DTM spacing), dH difference between extreme values of heights (relief) measured on GCPs and check points.
