Yes. Just do the same process to create Custom Maps, however you should save it to the computer in .kml format. Then just import that kml into BaseCamp.
For satellite images, you need to print in the GE and cut out the desired area and then make the image overlay with the same image you just cut from the print. This process is for any type of image. Be it satellite or even an old topographical map like the one from the 60's here from Brazil. All you have to do is reference in GE the corners with known coordinates and everything ready to overlay the image and save in KML.ciq.forums.garmin.com/.../1466051.jpg
