Kurzfassung

Undocumented buildings are buildings which were built years ago, but were never recorded in official digital cadastral maps.Detection of undocumented buildings is of great importance for urban planning and monitoring. The state of Bavaria, Germany,pursues this task based on high resolution optical data and digital surface models, using semi-automatic detection methods, whichsuffer from a high false alarm rate. In order to study the influence of sampling strategies on the performance of building detection, we have firstly designed a transferability analysis experiment, which has not been adequately addressed in the current literature.In this experiment, we test whether the trained model from a district contains valuable information for building detection in adifferent district. It was found that the large-scale building detection results can be considerably improved when training samplesare collected from different districts. Based on the building detection results, we propose a novel framework for the detection ofundocumented buildings using Convolutional Neural Network (CNN) and official geodata. More specifically, buildings are identifiedas undocumented, when their pixels in the output of the CNN are predicted as ”building”, whereas they belong to the ”non-building”in the Digital Cadastral Map (DFK). The detected undocumented building pixels are subsequently divided into the class of old or newundocumented building with the aid of a Temporal Digital Surface Model (tDSM) in the stage of decision fusion. By doing so, aseamless map of undocumented buildings is generated for 1/4th of the state of Bavaria, Germany at a spatial resolution of 0.4 m,which has demonstrated the use of CNN for the robust detection of undocumented buildings at large-scale.
