Comparable distortions will probably be observed alongside sheet edges that image tall buildings. Significant bridges can even be a source of mistake or distortion. By transferring the terrain under the bridge to eliminate reduction displacement the actual bridge may perhaps show up out of alignment with the connecting freeway. In these instances, it is necessary to regulate the image to move the bridge again into alignment with the road to make an optically pleasing image.
Other clearly seen factors like swimming pool corners, web sites in parks and also other areas will help guarantee the accuracy with the image. By plotting the points from the GPS assortment around the digital image, it can be then attainable to evaluate the difference between the image and the GPS position. In addition to examining the absolute difference between these areas, the way of any discrepancy should also be noted to test for the opportunity of a systematic error.
