A world map I made in Photoshop for a project. The only thing that's not noted on the map is the smaller islands and tiny countries, and some provinces of other countries, most notably the islands beneath the Dominican Republic which are so mixed up it's insane.
The Photoshop document has a few layers - the text, the compass rose, the lines and dots, then the border lines and finally the background textures. If you don't have photoshop, the preview image here is a full quality jpeg, this is pretty much how big the picture was made at
