Last year and the year before I drew a bull tag and cow tag in Wyoming, both ares I had never hunted before. I bought forest maps primarily for land status, talked to the Fish and Game guys and spent hours on Google Earth. I killed a bull in one one of the areas I had written down the GPS coordinates for. Last year our three cows were killed in a little basin a couple of miles in. Nothing beats first hand knowledge but maps and GE can save a lot of miles, and days.
