Terra is NOT usable yet.

Tile38 is an open source (MIT licensed), in-memory geolocation data store, spatial index, and realtime geofence. It supports a variety of object types including lat/lon points, bounding boxes, XYZ tiles, Geohashes, and GeoJSON.

Terra is a Tile38 based Geofence server in Rust. Terra is meant to be a memory-safe and highly concurrent geofence server. Terra is meant to be used for my personal location-based projects. It in no way is a replacement for the amazing Tile38 server, but is actually an augmentation to it.

Terra is NOT available as a crate on crates.io yet, although I plan to.

Terra supports two types of Geofences: Circular and Polygonal. (so far)

The easiest way to to clone the project and run as a Rust binary project like this:

~$ git clone https://github.com/younisshah/terra.git

~$ cd terra

~$ cargo check

~$ cargo build

~$ cargo run

If all went well, you'll see something like this:

          ________
          ___  __/_____ ______________________ _
          __  /   _  _ \__  ___/__  ___/_  __ `/       Terra is a Tile38 based Geofence server.
          _  /    /  __/_  /    _  /    / /_/ /        v0.0.1
          /_/     \___/ /_/     /_/     \__,_/

[+] Checking if Tile38 is running at '127.0.0.1:9851' is live... <br/>
[+] Tile38 is RUNNING.<br/>
[+] Terra started! Listening for incoming connections on '127.0.0.1:9761'.<br/>

By default, Terra runs on port 9761 and expects an instance of Tile38 server running on it's default port 9851. However, the defaults can be changed. Run the following command to see Terra's usage:

~$ ./target/debug/terra --help

Terra 0.0.1 <br/>

 USAGE:<br/>
     terra [FLAGS]<br/>

 FLAGS:<br/>
         --help        Prints help information<br/>
     -h, --host        Set the host address to listen for new connections<br/>
     -p, --port        Set the port number to listen for new connections<br/>
         --t38_host    Set the host address of Tile38 server<br/>
         --t38_port    Set the port number of Tile38 server<br/>
     -V, --version     Prints version information<br/>

Once, Terra is up and running, create a WebSocket connection like this.

This is a JS client. You can use any WebSocket client:

const socket = new WebSocket("ws:https://localhost:9761");
socket.onmessage = function(event) {
  console.log(event.data);
};

Send fence creation request:

Send the following data:

const fence = {fence_type: "circle", fleet_name: "my_circular_fence", lat: "12.3", lng: "34.4", radius: "6000"};
socket.send(fence)

Send the following data:

const fence = { fence_type: "polygon", fleet_name : "my_polygonal_fence", id: "some_id", coordinates: [[12.12, 43.32],[12.12, 53.32],[12.4, 55.2],[12.12, 43.32]]};
socket.send(fence);

That's it!

• Write sane documentation.
• Expose server API.
• Change to a crate.
• Add more shapes of geofences.
