Such an update usually starts out with a manual change detection process. The main goal of this paper is to present a new method to automate the detection of changes in a 2D building database, starting from satellite images. The workflow of our approach is divided into 2 phases. Primitives, extracted from multiple images or from a correlation Digital Surface Model (DSM), are firstly collected for each building and matched with primitives derived from the existing database to achieve a final decision about acceptance or rejection. A specific algorithm, based on the DSM and a computed Digital Terrain Model (DTM), is subsequently used to extract new buildings. The method is here introduced and tested in two test areas, very different regarding the land use and topography. The out-comes of the method are assessed and show the good performance of our system, especially in terms of completeness, robustness and transferability.

[Termes IGN] valeur aberranteRésumé : (Auteur) In this paper, we present an automatic method for deriving Digital Terrain Models (DTM) from Digital Surface Models (DSM). The DTM generation is formalized here as the minimization of a given energy, defined by a data term and a regularization term. The main contribution of this paper lies in the specific module, introduced in the data term in order to filter outliers (non ground points present in the original DSM) so that the final terrain surface best fits true ground points (inliers). The method is here introduced and tested on a vegetated and hilly area. A comparison to ground truth is also performed and shows the geometric accuracy and the robustness of the approach.

[Termes IGN] test de performanceRésumé : (Auteur) 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.

[Termes IGN] mesure de la qualitéRésumé : (Auteur) In the past few years, 2D topographic databases have been completed in most industrialised countries. Most efforts in National Mapping and Cadastral Agencies (NMCAs) are now devoted to the update of such databases. Because it is generally carried out manually, by visual inspection of orthophotos, the updating process is time-consuming and expensive. The development of semiautomatic systems is thus of high interest for NMCAs. The obvious lack of expertise in the domain has driven EuroSDR to set up a test comparing different change detection approaches. In this paper, we limit the scope of the project to the imagery context. After describing input data, we shortly introduce the approaches of the working groups that have already submitted results. Preliminary results are assessed and a discussion enables to bring out first conclusions and directions.
