location2gpx

Crate API github sponsors

GPX file generator from consolidated sources.

Visualize or manipulate your tracks with a .gpx file from raw data in mongodb collections or CSV.

How location2gpx works

  1. Connect to your source and fetch all the records of provided range
  2. Groups all your positions by a device and route
  • Each device + route will be a GPX track
  1. Track positions will be split by a maximum time value into GPX track segments
  • In segment you have all points with elevation, speed and time
  • If desired, each track segment can be simplified with the Visvalingam-Whyatt algorithm
  1. Your GPX file are ready

How to use

With mongodb:

cargo run -- mongo "mongodb://localhost:27017/yourdb" yourcollection "2020-01-01T00:00:00.000+00:00" "2020-12-31T00:00:00.000+00:00" /tmp/my-tracks-2020.gpx

With CSV file:

cargo run -- csv yourfile.csv "2020-01-01T00:00:00.000+00:00" "2020-12-31T00:00:00.000+00:00" /tmp/my-tracks-2020.gpx

Output will be like this sample.

How configure fields

To configurate, you need to setup a yaml file and use the --config parameter. You can also leave your config on your $HOME with ~/.loc2gpx.yaml.

Configuration example:

fields:
  device_id: dev_id
  time: dev_time
  coordinates: coords
  # route:
  # elevation:
  # speed:
segments:
  vw_simplify: 0.000001 # Tolerance for Visvalingam-Whyatt simplification algorithm
  max_segment_time: 300 # Max segment time(in seconds) allowed
