You can make your own maps derived from google earth.
Set up GE to whatever/wherever you want & then save the screen as a jpg. Don't forget to rid the GE screen of any superfluous info before saving!
Open the saved map in PP.
Select Options/Map Calibration/Add Calibration Point (Or toolbar 2 red circles) & fill in the info with Degrees, Decimal Minutes as indicated in GE.
e.g. Using google earth zoomed in to YSSY at 16R/25 = S33 56.470 E151 10.479. Add 3 or 4 points around the map, save & you should be good to go.
Have fun & practice
. Using this method gives good maps at *your* screen res.
