I now always fly the area with my drone, a great way to scout the area, looking for trails and even game or even if you are curious as to what is over the next hill. It's a great tool, never leave home with out it. I am looking to upgrade to one that will follow you as you hike along.
Illegal to use a drone for any purposes related to hunting, in BC. YMMV, check your regs. Between that the rest of the Provinces pretty much are going the same way, and the new Federal Laws around flying drones, you pretty much have to either push your luck pretty hard, or find a different way.
Google Earth and the various maps apps have pretty good coverage of air photos of most areas though, that can be a real boon for seeing what is where.
You can download pretty much any Topographical map that you may wish to, if you dig around a bit. Can be pretty out of date as far as stuff like logging roads, but the shape and height of the rocks is pretty constant. Worth looking at.
Luck favors the prepared mind!
Personally, I carry very little with me when I am out hunting. Usually a few snacks, some extra ammo, and a bit of twine or para cord. My whole hunting kit is built around a nylon fanny pack that I removed all the rattly zipper pulls from. I don't tend to be much more than a few hundreds of meters away from the vehicle or at least, a place I can drive the vehicle to.
The more time you can be out in the bush, the more critters you will see. Carry a decent camera. I have had Fisher's run past me, Lynx walk within a few feet of me, and have watched a great number of very grand vistas unfold as the dawn broke, looked out onto lakes that had their entire surface covered in geese, and onto fields that had a thousand or more whitetail deer on them, and took pictures of none of it. I carry a camera with me now.
I was always pretty certain I had a great day out hunting, if I went out hunting. Seeing anything at all, was success. Seeing shootable game, was just bonus. You can learn an awful lot about how the deer actually behave, by sitting and watching them. Especially when you wish to see how they react to such things as calls and rattling. Nothing like seeing a deer that is minding it's own business, react the way that you want it to when you start rattling, for example. On the other hand, if it immediately decides to head for the other side of the mountain, you pretty much know THAT technique isn't going to pull any in towards you, kapishe?
Enjoy being out there.
Cheers
