iPad drawing app to create outline maps

The iPad is one of the easiest ways to create digital artwork.  One way I use the iPad for homeschooling is to customize maps or to create a map outline using a drawing app.   I use the SketchBook Pro for iPad app, but you can also use the free sketchbook express app.  The only requirement for creating an outline map is that the drawing app has the ability to create layers.

To create an outline map just search for any map picture.  Import that picture to your drawing app.  Create a blank layer over the picture.  Then you can trace the main map details on your outline map.

Once you have your outline then you simply delete the original map  layer and then save your outline map to your photo roll.  Now you can use the picture in a number of ways for school.
