What is Aberfoyle Area Image Orthorectification about?

This technical memorandum summarizes the orthorectification and mosaicking of aerial images near Aberfoyle, Ontario. Ground control points were used to geometrically correct three images, but the resulting mosaic showed shifts and overlaps when compared to road and building vector layers. Orthorectification was then performed using a digital elevation model to reduce distortions. The orthorectified mosaic will be compared to the geometric correction to assess accuracy improvements from accounting for elevat
