Why all Google earth images are not aligned?
July 07, 2011 10:00PM
Google Earth imagery often looks like a quilt with different images stitched together.
Imagery comes from a variety of sources including aircraft and satellite even kites and air balloons. Imagery from different providers often have different resolutions and are from different times so the trick is to stitch the imagery together seamlessly. Further misalignment can be introduced if for example an aircraft camera is looking at the ground from an angle vs straight down since the look angle may add a distortion to the imagery.
The edges of such imagery can clearly be seen in Google Earth especially if looking at a large area.
