I have a geoTIFF file (pretty large) covering a good chunk of Spain around Almeria. I got it from the EU-DEM v1.1 data (25m resolution), freely available in which I have a route in lat/long and I want to look up the elevation values at each point or the surface-slope between points, but elevation might be easier.
- loaded the geoTiff in.
- figured out how to add a new layer that can be pointed.
- installed the point sampling tool and I found a GDAL function called slope that made a slope layer.
But I have no idea how I get QGIS to load in my sample lat/long points? and if that would even work as I see the coordinate system in the bar across the bottom seems to show pixel X, Y.
