Tools and Web services
A semi-automatic text annotation tool is developped by the project. It takes PDF documents as input and processes them automatically by applying the three following steps:
- layout detection,
- optical characters recognition (with PERO OCR),
- named entities recognition (fine-tuned CamemBERT model).
Users can then check and manually correct each automatically detected and processed text section.

A collaborative tool to validate and edit geospatial data and more is developped to improve data quality by getting a human validation of any type of geospatial data. It allows users to improve this quality by creating, removing, modifying or validating any feature (geometry and attributes).
