Tile38 – Geospatial database and realtime geofence. v1.5.0 – GRPC and 3d support

This looks cool! The GRPC support's what caught my attention, especially as I've found trying to pass GeoJSON objects around GRPC to be a pain.

One of the irritating things with Protobufs is the lack of support for nested JSON-style arrays, which GeoJSON LineString and Polygon use. I've seen some https://github.com/mapbox/geobuf but after trying it out for a bit, I felt it wouldn't work well for me.

Anyways, I searched the Protobuf files on the repo, but I can't find anything that gives me a guide on what's being done on Tile38. I'll have a deeper look at the source.

Great stuff. This is maybe exactly what I was looking for. The problem I have is when I have 20 queries in a given bounding box in LA, I have 20 queries towards the DB. Maybe it helps me reduce this to 1 with the rest being in memory.
