Simple LoRaWAN/HTTP based map position tracker

Trackerbrand

Trackerbrand is a simple proof-of-concept location history map. In its current use-case, data is added to the local Trackerbrand database (lowdb) via HTTP, coming from either a local script managing a GPS receiver or from remote via HTTP or HTTP via LoRaWAN gatewy.

Usage

• Map tiles are added as described in this stackoverflow post
• The databse must be created via POST request to /position/setup

Map viewing mode

The index file is served at /position/display. The passed hash specifies how the map is shown.
The following are valid display options:

• #show:current Shows the current position
• #show:live Shows the current position and updates position + map view every 10s
• #show:history,size=n Shows a history of the latest n positions
• #show:trip,threshold:t,interval:i Shows the trip point-by-point. Omitting points with a cumulative distance <t, adding a new point every i. (0.0007 has been proven to be a reasonable t for skipping port times)

Submitting lcoations.

Database must be set up once with a POST /position/setup An example of the payload that can be sent by a client to POST /position/add-remote to track a position:
