In this exercise a series of oblique photos, made in 1991, is available. On one of the photos a clearly new residential area is detected. The land use map of 1978 shows non-urban land use in that area. Transfer of the boundaries of the new site from the photo to the map is done by selecting tiepoints, common to the oblique air photo and a topographic map, and then applying a geometric transformation to integrate the new residential area into the land use map.
