Ground control point data collection is one of the most expensive and time consuming phases of a photogrammetry based mapping projects. Nowadays, Global Positioning System (GPS) is broadening its role in photogrammetric activities and mobile mapping from reaping Ground Control Points (GCPs) and measuring image center coordinates to rotating elements of camera system. Recently, lots of researches have realized to evaluate and study of using GPS data and their combination with INS (Inertial Navigation System) data to decrease the number of GCPs, for large scale mapping.
In this paper, we evaluate and compare the results of GPS based Bundle Adjustment (BA) with Independent Model (IM) approach in Iran 1:25000 scale maps blocks adjustment. The results demonstrate the sufficiency of the estimated accuracies for this scale.
