How do you draw borders on a satellite map image?

I have a 10000 x 5000 Satellite World Map image and I want to draw borders on it however I can't draw them accurately as I don't know where the countries actual borders are. What should I do?

Erase the map and quit map making.

or go and see ezzatam's tutorials.

Compare satellite map with a political map.

Use Hybrid. It's sattellite with borders.

Use Photoshop (or similar GNU programs) and put political map as layer above sattelite image... important is to have the end size accurately. Upload the image (satellite and political layers) into AW map environment. Draw the borders. Replace background (political and satellite layers) with only satellite map.

Just use my Overlay tool... Overlay Tool. Its simple to use get your map with borders... load it.. then lock it over your image you can draw now!

For me ,i usually draw the image or draw borders on a satellite map image using an image drawing tool.
