摘要：The update of databases – in particular 2D building databases – has become a topical issue, especially in the developed countries where such databases have been completed during the last decade. The main issue here concerns the long and costly change detection step, which might be automated by using recently acquired sensor data. The current deficits in automation and the lack of expertise in the domain have driven the EuroSDR to launch a test comparing different change detection approaches, representative of the current state-of-the-art. The main goal of this paper is to present the test bed of this comparison and the results that have been obtained for three different contexts (aerial imagery, satellite imagery, and LIDAR). In addition, we give the overall findings that emerged from our experiences and some promising directions to follow for building an optimal operative system in the future
