Hi Morgan, to achieve this, you need a digital elevation model (DEM) with a resolution that is not too coarse. I don´t know where you are located or what your area of interest is, so I can´t tell where you might get it.
Once you have your DEM, you can use raster functions like roughness, inclination or topographic position index to identify your spots. Hope that helps, regards Simon Von: QGIS-User <[email protected]> Im Auftrag von Morgan Fletcher via QGIS-User Gesendet: Mittwoch, 22.

I have a real-world need, a wish list item, and I wonder if QGIS might be able to solve it. I want to know where the flat spots are. Given a bounded area on a map, could I ask QGIS to find me all locations that are at least 100 square feet, with less then 1' vertical delta across that space? Yes, I'm trying to find flat camping spots. Morgan
