I love the bathymetry data from Natural Earth. I've been looking for the last few days for the same basic data but for land. I'm trying to find general elevation shapefiles, as polygons. I don't need it to be 100% accurate since it's just for appearance of a stylised map.
Unable to find it, I've been trying to make it in QGIS. I've managed to convert global heightmap data to a shapefile, but it came out as squares matching pixels. That's no good. Trying to convert contours to polygons doesn't work, obviously,
Is there a place to download elevation shapefiles equivalent to the Natural Earth equivalent bathymetry?
Why is it so hard to find lower resolution elevation data that's global?
