I am trying to run the urban flood risk mitigation model on a watershed in Ontario, Canada. I have found data sources for all the inputs, however, I am having trouble retaining the vector resolution after processing the building footprints programmatically in Python.
My data source is from GitHub - microsoft/CanadianBuildingFootprints: Computer generated building footprints for Canada and in geoJSON format. Ideally, I would like to crop down the geoJSON at a state/provincial level to the watershed area before converting to the required format for the model (.gpkg).
I was wondering how the building footprints from the sample data in the urban flood risk mitigation model were processed to cover such a smaller region.
Thanks for the help,
