I did some research about creating my own WMS and came across the Natural Earth Project. The web page says:
Natural Earth is a public domain map dataset available at 1:10m, 1:50m, and 1:110 million scales. Featuring tightly integrated vector and raster data, with Natural Earth you can make a variety of visually pleasing, well-crafted maps with cartography or GIS software.
How can I harvest the data for my WMS So that it can be used with Mapinfo or other software?
