I'm working on a project to analyze data at multiple geographic scales for nation states in Africa, and I noticed that data for some countries administrative boundaries are missing. For example, a search for 'Ghana' in the Living Atlas yields layers for Country, Region, and District boundaries, but a search for Burkina Faso comes up empty. I know that there is a layer for global country boundaries, but it would be much more useful to analyze data at more local scales.
Is there an alternative suitable layer? Or an acceptable source where I could submit boundary layers from?
