I've downloaded some .asc files from the UK Government. They are 1m resolution LIDAR tiles. Apparently.
When I load them into QGIS, they appear with the nice thumbnails and everything. But I get errors about no CRS and defaulting to CRS EPSG:4326 WGS84. I think that is the standard model for the globe?
When I try to load the .gpx file for my route, it is no where to be seen. I think the .asc files dont have coordinates or something? I was expecting the trace to appear over the top so I could pull out surface elevations.
