Mapping Trophy Bucks would be a good start.
Google "usaphotomaps" and download that free program from JDMCOX software-- free topo and aerial maps.
I use an old Garmin Etrex. It interfaces with USA Photomaps. I start looking for funnels, points, saddles, shelves and edges-- the usual stuff, and then I go scout the ground extensively. Somewhere in this, I start finding tracks, and I work from those to find beds at one end of the track and food sources on the other.
In 30 - some years of reading topos, I can tell you this:
1) Topos, aerials, etc. will give you great places to start
2) Until you put feet on the ground, you will not have the whole story
3) Until you have spoor to examine, you won't have squat.
4) The remote sensing (maps, photos) have never directly produced a big buck for me, but it does put me onto the first good set of tracks that eventually lead to something.
The absolute worst time to begin scouting is in late summer and early Fall. All the signs from late Fall of last year are long-gone. The absolute best time to scout is right after season ends and into the Winter. I've gone done more blind alleys chasing summer sign than I care to count. However, after the last shot is fired, I can go back and see the error in my ways and adjust. How this Winter sign relates to maps and photos is key.
The other bit of gold I find from remote sensing is how it helps me extrapolate. If I see deer at Point A, I should be able to find structures that are similar to Point A elsewhere on the property and they may be productive. These become the targets of futher scouting.
