TrackEngine Integration Configuration

This section of the database.properties file controls the TrackEngine module integration, including the executable path and whether the system should automatically provision the required runtime and data files.

`trizdistribution.dossier.chemain.trackEngine`

Property	Value	Description
`trizdistribution.dossier.chemain.trackEngine`	`C:\TrackEngine\bin\TrackEngine.exe`	Absolute file-system path to the TrackEngine executable.

What it points to:

TrackEngine.exe is the compiled native binary of the trajectory processing pipeline.
This is the entry-point program that orchestrates the T-DBSCAN → Douglas-Peucker → OSRM pipeline described in the main configuration.

Usage:

The application launcher or service wrapper reads this property to know where to invoke TrackEngine.
Ensure the path uses escaped backslashes (\\) as required by Java .properties file format.

`trizdistribution.trackEngine.enabled`

Property	Value	Description
`trizdistribution.trackEngine.enabled`	`true`	Feature toggle that enables or disables the TrackEngine module.

Behavior when true:

The system downloads the TrackEngine runtime (if not already present at the configured path).
The system downloads the required OSRM road-network data (e.g., algeria-260108.osrm) into the TrackEngine data/ directory.
The trajectory processing pipeline becomes active and can be invoked by the application.

Behavior when false:

TrackEngine is not initialized.
No automatic downloads occur.
GPS trajectory processing features are not going to work.

Provisioning Flow

When enabled = true and the application starts:

Check TrackEngine.exe at configured path
        ↓
   [Missing?]
        ↓
  Download TrackEngine binaries
        ↓
  Download OSRM dataset (algeria-260108.osrm)
        ↓
  Place files under C:\TrackEngine\
        ↓
  Ready to process trajectories

The provisioning step ensures the deployment is self-contained: even on a fresh machine, enabling the flag guarantees that both the executable engine and its underlying road-network graph are available before any GPS data is submitted.
