A common characteristic of these methods is the requirement of an existing approximate position (AP) of the building to be registered. In the present work, we develop a method for producing such APs based on sets of true colour (RGB) or colourinfrared (CIR) aerial imagery in combination with prior registrations from a {GIS} database. The primary intention with the work is to support the automated update of the {GIS} database. At the current stage of the project, the main goal is to produce a dataset where as much as possible of the “non building” area is masked out." }
