- The first step is the creation of the paper-based maps. Participants can choose between basemaps containing [OpenStreetMap (OSM)](www.openstreetmap.org) data or basemaps containing satellite images. In addition, the tool can evaluate how well-suited an area of the OpenStreetMap (OSM) basemap is for participatory mapping. This evaluation is based on a quality analysis of the OpenStreetMap (OSM) data using the [HeiGIT ohsome quality analyst](https://heigit.org/de/big-spatial-data-analytics/ohsome-3/ohsome-quality-analyst-oqt/).
- Usually, the data is collected on site and offline through participatory mapping. For this, you only need participants, printed Sketch Maps and pens to draw markings on the Sketch Maps.
- After mapping, the Sketch Map Tool supports the digitisation of the Sketch Maps. Upon uploading the pictures or scans of the marked Sketch Maps, the Sketch Map Tool initiates an automatic georefferencing and colour-detection process. The tool uses a combination of computer vision algorithms and novel AI models to extract Sketch Maps from photos and detect markings on them. The results can be downloaded in various geodata formats. The results can then be used for further analysis in Geographic Information System software (such as QGIS).
