Does anybody know where you can get shapefiles of the major regions and continents of the world in WGS 1984 (or system than can easily be converted to WGS 1984 or sinusoidal sphere)).
I list them below, just for you to get an idea about how big the scale I need is.
South east asia
Rest of asia
rest of europe
So far I have only found country level data in WGS 1984. The regional/continental data has been in format where it wasn't so eay to convert and the data has been quite coarse. It would be prefereably if the data as relatively precise.
Thank you very much!
