I looked at getting gis data from my local county. Sent an email and all I got was crickets.
It all depends on where you are at and what's available to tap into, as far as gis is concerned.
I tried to make a tree location map using phone gps meta data a couple of months ago. What a mess, the precision is too low. You can buy precision gps receivers, but they are expensive. It was a great exercise though. Now I know why trail navigation apps fail around closely spaced switchbacks in mountain areas. The gps data is too imprecise.
Not only gov data, but also custom map I wrote, have you tried Bluetooth beacons ?
You would be surprised how far you can go if you ignore these expensive APIs and build your custom stuff. People are lazy, if any big corp does something, they immeasurably avoid it and start building their 1000th note taker app.

But maybe you know more than I
