Where can I get a freely usable geo dataset of the Great Wall of China? I would prefer a (Multi-)LineString, not something with an area but any format is ok. Vector data in any format, as long as I can somehow get it into GDAL/OGR or similar free software tools.

The only datasets I found are not publicly available and under very restrictive licenses.

OpenStreetMap has a relation (https://www.openstreetmap.org/relation/318110 (warning, huge)) but it is disconnected and incomplete.

  • Could you clarify exactly what you want this in, shapefile, x/y coordinates of the path?

    I would take any format, prefering something vector but would even take a raster set if the resolution is good enough.

Here's a website which links to a project related to the Wall and a few resources in kmz format. I haven't had a look at the actual data though.

There should also be a dataset here, according to ResearchGate.
