Figure 1. Modeling selection in OrthoEngine v8.2.3 In this stage the Ground Control Points (GCPs), Check Points
| (CPs) and Tie Points (TPs) will be selected. For Rasht region,
One of the problems about this model is that the user has no with using the provided digital maps, the 17 GCPs and CPs (all
idea about the model and one doesn’t know how the model of them are full control point) have been selected. These points
handles the satellite orbit metadata. Thus, the user has no idea are in accuracy of 1:25000 maps. Figure 2, Figure 3, and Figure
