INTEGRATION OF MULTIPLE COLLECTED POLYGONS WITH A RASTER-BASED APPROACH

Abstract. In this paper, we present an approach for the integration of multiple collected (vector-)polygons that is computed in the raster domain. In a first step, all polygons are transferred to the raster domain with a vector/raster-conversion. The integration in the raster domain is a simple pixel-wise summation that is much simpler than comparable approaches in the vector domain. The results can be optimized with image processing operators. Finally, the integrated data are transferred back into the vector domain with a raster/vector-conversion. This approach can integrate not only 2 datasets but is also able to integrate n datasets without any modification. We will demonstrate this approach on data that was multiple collected in a student project and we will discuss how the integration results can be evaluated with quality measures.
