Piggy-backing off @knifebladepresents - I would really love an app that shows the best locations for shooting. I've tried doing research on this a few months back, and couldn't find anything except for an app that shows you 1000+ locations where famous movies were shot.
I remember Freddie talking about location scouting a long time ago, (FreddieW days) and he was also saying that when you're looking for a location, it's not how good the overall location looks, it's how good a certain part of it looks on camera. Plus, I feel like a lot of people here are small budget-ers, and we don't have every department and each department team for our films, so that makes it easier to location scout IMO.
I think one of the biggest problems with beginner filmmakers (I was and still sometimes guilty of doing this myself) is that they don't take the time to explore their city and really look for some good locations. That's basically what I did when I first started to do live action filmmaking, thinking "wow this movie would be so much better if I was in Los Angeles." But the truth is, there's probably some locations around you that you may think are not a big deal, but when you point a camera to it and set up a shot, it becomes a whole new location. Just my thoughts anyways!
