What is required to replace the default base maps in TerriaMap?

What is required to replace the default base maps in TerriaMap? - i.e. different sources, thumbnails, etc.
Do I need to create new ViewModel?

Thanks!

Hi @lstillwe

Yes, you can do this in TerriaMap.

I copied the whole createGlobalViewModels.js from TerriaJS into my TerriaMap fork lib/ViewModels and modified it by adding a new map.

Then edit index.js such that you use your modified copy rather than the one from TerriaJS

var createGlobalBaseMapOptions = require('./lib/ViewModels/createGlobalBaseMapOptions');

I think this is the recommended approach. Someone else will tell us if there is a better way.

Good luck.
