I want to be able to draw a map using my GPS tracklogs as a guide. What I envisage is saving the above image as a JPEG or something and then bringing it into an app and being able to use the JPEG as a guide to help me create an Apple Pencil drawing on a separate layer. And then save only the separate layer.
Are you aware of any apps that might help in this respect?
PS: if case you are wondering, the map above is of the Tafraoute area of Morocco, per photos at http://www.morocco-knowledgebase.net/forum/showthread.php?t=200
