I don't know if 1:10,000,000 is a large enough scale for you, but if it is, you might want to look at Natural Earth. Public Domain<br>

You could also look at OpenStreetMap data. <a href="http://www.openstreetmap.org/" target="_blank">www.openstreetmap.org</a> Most of the coastline data was imported from the Prototype Global Shoreline dataset <a href="http://wiki.openstreetmap.org/wiki/Prototype_Global_Shoreline" target="_blank">http://wiki.openstreetmap.org/wiki/Prototype_Global_Shoreline</a>. This data has been improved in some areas.<br>

Any suggestions where to find vector maps? All the ones I have found are somewhat squishy in their placement of islands and the details of coastlines. I have tried geological survey websites plus the general commercial web. I have some older maps I may scan in and trace the vectors myself. How do I determine the projections of these maps?_______________________________________________<br>
