Thanks for the information. Initially, I’m most interested interested in the country/province datasets. Most of the available ones have some serious problems. These look quite good! Thanks for releasing them.

Hi,

I prepared a tiled image layer of the Natural Earth imagery for World Wind a couple of years ago.

It has consistently been one of my most popular add-ons.

I’m more used to working in dimensions and resolutions than scales, so you will have to convert this to 1:whatever. The Natural Earth add-on above is 32K x 16K resolution at the highest level (4 levels, 4×8 x 512px = Level0). WW will accept any 1×2 tiling scheme, 5×10 is the most common.

There are 2 datasets of this type for WW, that I know of. The Demis World Map

is pretty nice, but the background map is kind of simple. It goes to nine levels (4×8 base).

There is also a plugin for Microsoft’s Virtual Earth that goes to 20 levels, but crashes the program a lot.

These are both served as tiles.

You will never get anything that large into a manageable package to download if that is what you have in mind. My Natural Earth add-on is ~200 MB (64 MB Installer). It only includes the land areas, overlaid on a small blue texture, to reduce the size.

I take it that you realize the size will quadruple with each level.

btw: Have there been any dramatic changes since then, that I should worry about updating it? It appears that the version that I used (LC_SR_16200 E&W) is larger than the resolutions you currently offer. Unless there were major changes, I’m probably better off with what I have.

Regards
