Waterproofing Data Project: Participatory flooding maps for flood-prone neighbourhoods The zipped file contains two folders with the files used to create the flood perception maps. To use the files and re-create the maps you need to install qgis https://www.qgis.org/en/site/forusers/download.html The project files that define simbologies and map formatting are inside the folder ?PROJETO?. The files have an extension .qgz. If you plan to generate new maps within a new GIS project you can explore and open the layers in ESRI Shapefile format. The layers are inside the folder ?SHAPES?
