Show HN: Tile38 – Realtime geofencing and geospatial index

[alleycat5000]

One 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

This 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?"

[tidwall]

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.

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

I am just now digging a bit into IFTTT like event driven api pipelines (OS of course) and so the "Automated Events" section on tile38.com hit my attention - niiice!

I just today found this interesting project:

http://www.flogo.io/

and this seems to be a great fit! Very nice toolset!

NO, I am not affiliated, I just liked it. I tried several different things, Flogo seems to have hit a nice spot between "general, but not too generic tool" with easy extensibility but still good usability for gui experiences.

Adding an event capable mapping server to the toolbox triggers exciting ideas!

Thank you very much for making this fantastic project a present to the world! Great!

This is an amazing piece of software and thanks for creating this. We heavily use Tile38 for all our Geospatial needs in production.

[tidwall]

You're welcome and thanks so much for kind words!

Hi ! Thanks for creating this project. This looks extremely usefu l for the current project I am working on.

Question : is it possible to do a Nearby query on a geohash ?

[tidwall]

Hi! I recommend converting the target geohash to a lat lon first and then using the NEARBY command.

  NEARBY fleet HASH POINT lat lon

This will return back all points as geohashes.

Tile38 is a great product, we've been using it in production to track, and manage geofences for a large amount of asphalt and cement trucks :)

[tidwall]

Sweet! I'd love to hear more about your implementation.

@tidwall: the link to maptiler.org in the readme is broken (it has bad certificate + asks for login & password)

[tidwall]

Oh thanks! I just fixed it.

I wonder how much work it would be to integrate with Owntracks. It looks like Tile38 supports MQTT.

What does this give you beyond what nearest neighbor libraries like flannel already do?
