Wikipedia:WikiProject Maps/Source materials

The Wikipedia Library (talk | edit)

...Support Open Access...

In creating geographical maps for Wikipedia, it is often useful to have high-quality source material such as blank outline maps, Adobe Photoshop or GIMP-format images with layers, SVG files and so on. If you have such source material that you think may be helpful to other map authors, please feel free to upload it to Wikipedia and list it here.
