Idiopathic pulmonary fibrosis (IPF) is the prototype of fibrosing ILD, and is characterised by irreversible progressive pulmonary disease, accounting for loss of lung function, exercise intolerance and complications, especially acute exacerbation and respiratory failure leading to early mortality. A significant proportion of patients with fibrosing ILDs other than IPF will develop a progressive phenotype comparable to untreated IPF. Such progression can occur despite conventional treatment which, depending on the underlying condition, may include close monitoring, antigen eviction, glucocorticoids, immunosuppressive therapy and pulmonary rehabilitation. Progressive pulmonary fibrosis (PPF), also referred to as “progressive fibrosing ILDs” (PF-ILD) or fibrosing ILDs with a progressive phenotype, is characterised by a disease course similar to that of IPF, with worsening respiratory symptoms, decline in lung function and early mortality. The open-source OpenGTS web-based GPS tracking system is well established and allows the detailed management of tracking devices. However, the mGTS mobile phone client for OpenGTS only works with older versions of Android (a Nexus 5 phone running Android version 6.0.0 in our case). The Traccar open-source web-based GPS tracking system works with a broader range of GPS clients and protocols and the Traccar Client works with recent versions of Android. It is therefore useful to integrate Traccar with OpenGTS. In the case of Jura Mountains' mapping, being able to monitor the routes one actually followed in exploring historic paths and tracks allows us to check the accuracy of the JuraMap map. However, several issues arise so it is probably useful to summarise how to install and integrate self-hosted instances of OpenGTS and Traccar. These implementation notes are for Ubuntu 18.04 LTS on HPE ProLiant DL20 Gen10 servers. Traccar installation a) InstallationĪs explained, the Traccar installer package (for Linux 圆4 and other systems) can be downloaded from. We have not been able to integrate the latest version of of Traccar (version 5.3) with the latest version of OpenGTS (version 2.6.7) since there is a "tc_attributes" error on starting the Traccar server when it is configured to use an OpenGTS database. So these notes are for the last Traccar version 4 release (4.15) that is available here. It is probably wise to make sure that Traccar works before carrying out the integration with OpenGTS. Zip into say "/home/user/traccar" gives a shell script ("n"). One then needs to edit the "traccar.xml" configuration file and maybe the "default.xml" configuration file, both found in "/op/traccar/conf". The traccar installation creates a database called "traccar" with "root" as the user so traccar.xml needs to be edited in the obvious way: The important entries in "traccar.xml" are for the database. Updating of the database structure should also be disabled by removing the entry: Jdbc:mysql://127.0.0:3306/traccar?allowMultiQueries=true?įor default.xml, it is probably wise to disable the geocoder:Īnd to remove the other geocoder entries. It is perhaps useful to know that the Tracar database uses the InnoDB storage engine. The Traccar installation ensures that InnoDB is used. An OpenGTS database however needs to be MyISAM. Recent versions of the Traccar Client use the OsmAnd protocol to report GPS data. With an Apache2 webserver set up as a reverse proxy for both normal and unencrypted data traffic, the server URL in the Traccar Client can be of the form: The Traccar server "default.xml" file shows that osmand uses port 5055. This is also the case for Traccar integrated with OpenGTS where Traccar writes data to an OpenGTS database called say "gts".īoth the Traccar and OpenGTS web interfaces will of course require encrypted traffic so the fact that the Traccar Client (and indeed the mGTS Client for OpenGTS) do not require encrypted traffic does not mean that one can ignore setting up a reverse proxy for encrypted traffic.
