Common use of PROCESSING SOFTWARE Clause in Contracts

PROCESSING SOFTWARE. Once the data has been collected and accepted in the field, it is transferred to Fugro’s production center for processing. Fugro has chosen the state-of-the-art and sophisticated software package, PictoVeraTM, a robust oblique processing solution developed by Stellacore Corporation to process data. Step 1 PictoVera will ingest the platform trajectory data captured during aerial acquisition (i.e. navigation and camera data). The software analyzes the sensor data and uses the derived information to match sensor features between multiple images (along track, cross track, and above/below track simultaneously). Step 2 The image data matches are utilized as generalized "tie points" in a photogrammetric bundle adjustment which computes "best-fit" corrections to the nominal (drift and otherwise biased) trajectory data. This results in a much higher fidelity trajectory, one with which images can be geo-referenced within about one pixel. Step 3 PictoVera preserves the integrity of the photogrammetric adjustment from the GPS-based acquisition data and uses the planimetric and vertical control to fit the output products to the desired output geodesy. Thus, the effects of the systemic influence on fidelity are lessened. Step 4 The results of the adjustment are further verified through the development of rectified image samples for the platform trajectory. These images are inspected by the photogrammetric technician to identify any gross errors in the adjustment, as well as the identification of any voids or image quality problems.
