I can see where what you are talking about doing would be handy, to say the least. But the truth is that the only time really that you can't figure it out using satellite and street view on Google maps is if a place is too new to show on there or it has inside or underground docks not facing the street and even then you can tell on most places with indoor docks just by passing attention to where trucks are sitting and marks seen on the ground. I don't see making much if any money off the idea because most of the information is already out there and most folks know how to find that information free of charge.
Incedentally, for those that are complaining about using technology, I grew up fascinated by maps, I aced my quarter on mapping in AFJROTC and was used to tutor other students because I was ahead of the lessons just because I grew up around truck drivers and got interested in playing courses and figuring miles and time several years before high school. With that said, I know enough to use the best tools available to me to make my job more efficient and easier, so yup, I guess I have a GPS and smart phone stuck up my ass, but I can still read a map, chat a course over land, sea and air using just paper maps, but with my technology still up my ass I can tell you almost 90 percent of the time exactly which street route will be the easiest to get into a place, exactly where the docks, driveways and guard shack are, heck I can even tell you if an individual sign or pole is going to be a problem, and I can tell you generally how long I'm going to be at a facility and what the people are like and what product I'm going to be hauling and whether it's likely to be a heavy load or not. I can tell you all of this before I'm empty on my prior load usually. So yup, I'll take that technology stuck up my ass, no problem.
