I've already created a detailed outline of the island using Google Earth in SKP. The Island is mostly quite rugged terrain overall. I'm fairly new to SubD/Vertex Tools & see the advantage of using the Quad mesh. Do you think SubD/Vertex Tools would work for this approach? I was going to break the Island up into large blocks (sections) to work on at first with maybe a grid format of 5000mm? to get started & then infill areas as required. Any suggestions would be greatly appreciated. Thanks Steve
Sorry if i answer late (too late i suppose) i missed this post at all.
This can actually work. i'm pretty sure because i did a similar project and achieved a good result with the very same process you've described..
you can convert the low poly google earth mesh to quads, then detach some plate in the areas were you need more detail and use a mix of sub-d and vertex tools to add geometry and deform it as required..
you will get an heavy, but still workable model, if you manage it properly..
