Accuracy Improvement for Italian Digital Cadastral Maps

The original implant map (OI) of Italian Cadaster was first made out of topographical measurements. These maps have never been used for public consultation, but they are the most accurate ones. The publicly accessible maps are named "visure maps" (VM) and were obtained from the original implant maps and consistently updated. However, these maps have suffered many deformations due to continuous use over time. These VM were then vectorialized at the beginning of the 2000s and have therefore undergone a further process of degradation. The goal of this work is to improve the accuracy of the Italian VM using the metric informations. This can be achieved if we can precisely model the deformations, measurable by the recognition of boundaries and details still present on both maps and, after this, to apply this inverse model to the visure map
