Field notes
Each hex carries multiple layers, including built-up land, vegetation, cropland, water, population, elevation, and a flood-screening value. The page says scores compare scenarios within one place, rather than serving as a cross-place ranking. Its place-builder instructions describe adding surrounding land so a city map can include nearby farms, rivers, and forests; generating that file requires running a notebook in Google Colab.
