EXTOPIA was a project that has been executed in 2020 by the Administration du cadastre et de la topographie in order to evaluate the feasability of automatic extraction of topographic objects from aerial imagery using artificial intelligence, especially deep learning tools.

The project was funded by the Ministry of Digitalization in the context of the AI4GOV Program 2020.

Several contractors had been invited in a tender process and the project has finally been executed by GIM nv from Leuven, Belgium.

The results are very satisfying and the tools are available for the ACT on the Govcloud infrastructure of the CTIE.

This dataset is meant to describe the project and to publish the final report.
