Big Tracker

The Big Tracker will be a general purpose geospatial and distribuited server application, which aims to implement resources to solve most of problems related with object monitoring and queries by position / time.

Data Model

Big Tracker represents all data using GeoJSON. For more details, read RFC7946

Distribuited System

In context of geospatial data, the majority of applications might support eventual consistence when availability is garanteed. Having that in mind, Big Tracker is a cAP application.

For more details, read about CAP Theorem.

Communication Protocols

This application implements communication's interfaces in this two following protocols:

MQTT

MQTT is a extremely lightweight messaging protocol, whereby positions of objects will be sent to Big Tracker.

HTTP

Big Tracker will implements a GraphQL API to query several informations, like:

  • Last position of an object;
  • Position history of an object between hours;
  • All objects that who have been in a radius of some location in certain time;
  • etc.
