Your needs are a lot like mine, although I typically convert GPX to geojson.
For that kind of elevation resolution you are probably going to need LIDAR data. I don't know the capabilities of QGIS to use LIDAR data directly. One software we use for LIDAR data is Karttapullautin. Mike Flannigan Houston, TX On 10/23/25 00:16, [email protected] wrote:

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
