Cartographic web application to track moving objects equipped with a GPS.
This application is used by the Ecrins national Park to follow ibex : http://bouquetins.ecrins-parcnational.fr
Based on Followdem-admin (https://awesomeopensource.com/project/PnEcrins/FollowDem-admin) to install before to create the PostgreSQL database, manage devices, animals and attributes. It also allows to import massive GPS data.
French version of this presentation : https://github.com/PnEcrins/FollowDem/blob/master/README-fr.rst
General principles :
This application allows to track position of several objects (animals, bus...) equipped with a GPS.
Each object has an ID. They all transmit their GPS position to a satellite at regular intervals.
Then the application download these GPS positions to upload them in the MySQL database. For that, a TXT file is sent to an electronic mailbox for each object and each position.
A task (
import_imap_csv in file
/classes/controler/controler.class.php) is executing these steps :
This task can be executed manually or with a CRON launched automatically and regulary.
Other ways to fill this CSV could be considered :
tmp/csvwithout connecting to a mailbox
Demonstration and features
Try it at http://bouquetins.ecrins-parcnational.fr.
It includes a list of tracked objects, the map of tracked objects, a tool to select data duration.
When you click on an objects on map, click on "Voir le parcours" to show his recent travel. Then you can change duration (last 15, 30, 60, 90, 120... days).
You can also click on one position to view the day and hour, altitude and temperature.
All datas are collected in real-time and automatically from GPS positions of each ibex.
Our aim with this application was to do something very easy to use for everyone (schools, tourists, scientifics, curious...) that want to understand how ibex are moving.
We have another internal tool with more functionalities for our scientific program.
We learnt a lot with this GPS program. Here is just an example of an ibex that travelled to Italia : http://www.ecrins-parcnational.fr/actualite/un-bouquetin-des-cerces-en-italie
