#2This is definitely a cool product. I've been thinking of building something like this for use in a game server backend.
Do you plan on adding height-support? I'm sure some clients in the professional space would like to know "what room/floor in this building are you in?"

I'm curious to know where one gets such "heigh-support" data from?

I'm glad you like the product.
Today it's possible to assign a Z coordinate to an object, which allows for querying on Lat/Lon and filtering on Z.

If I worked in the advertisement space I'd probably install WiFi networks that could broadcast SSIDs at known mac addresses that are coded to a height. I could install apps on user phones that could read that and pull out height & building name data.

That's really cool! The only other optimization that I wanted to try and do was to use GPU acceleration to support huge numbers of shapes and entities. Something similar to what's described here [0]. I think it would really help for very very large numbers of entities or large complex geometry.

GPS gives you a 3D fix (lat/lon/height). A common use case in aviation, particularly drones, is avoiding controlled airspace. The height of controlled airspace varies with location - for example a rural area might be 7500ft while near an airport traffic zone it might be only 1000ft or lower.

#8One thing I've found hard to find in Go is a library equivalent to GEOS/JTS; looks like there are some nice geometric operations bundled under https://github.com/tidwall/geojson

GPS isn't too great in skyscrapers. In most current gen smartphones GPS can only really pin you to a 16ft resolution on a current gen smartphone in ideal conditions [0]. This gets worse indoors and if the target is moving.

It wouldn’t necessarily need to come from GPS. You could use beacons (ble) or similar to augment the raw dataset.
