[Qgis-user] Finding a flat spot

[Mike Flannigan]

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.
