摘要：The growing fields of GIS application (local administration, tourism, archaeology, geology, ...) has increased the interest in studying the information sharing from different geographic databases, also known as "GIS data interoperability". This is a huge problem, involving several aspects. Among them, we decided to concentrate an a geometric conflation of different maps since maps coming from different sources often show significant geometric differences. In order to solve, or at least mitigate this problem, a number of different approaches were proposed in the past years. Particularly referring to the specific case of vector maps, almost at the same scale, recently the authors presented a possible solution based on the automatic detection of homologous points on different maps and a further transformation based on multiresolution spline functions. To extend the proposed approach also to the case of raster maps, the possibility of using the point matching approach on vectorized maps obtained from raster ones was investigated. In order to avoid duplicating the effort of developing software and, at the same time, of taking advantage of existing free code, the first attempt, here presented, focuses on the application of our method on vectorized maps obtained by using the software Ras2Vec
