Installation
LIRiAP can be installed and used in two ways in QGIS.
This method is useful for quick testing and experiments without enabling a full plugin.
-
Locate your QGIS scripts folder:
- Windows:
C:\Users\<username>\AppData\Roaming\QGIS\QGIS3\profiles\default\processing\scripts\ - Linux:
~/.local/share/QGIS/QGIS3/profiles/default/processing/scripts/ - macOS:
~/Library/Application Support/QGIS/QGIS3/profiles/default/processing/scripts/
- Windows:
-
Copy the algorithm pack: Copy the
LIRiAP_packfolder into the scripts folder -
Restart QGIS (if already open)
-
Use the algorithms: Open Processing Toolbox (
Processing→Toolbox), search for "LIRiAP", algorithms appear under Scripts → LIRiAP
- Doesn't require enabling a plugin
- Changes require QGIS restart
- Good for testing
Recommended for regular use with better QGIS integration.
-
Locate your QGIS plugins folder:
- Windows:
C:\Users\<username>\AppData\Roaming\QGIS\QGIS3\profiles\default\python\plugins\LIRiAP\ - Linux/Mac:
~/.local/share/QGIS/QGIS3/profiles/default/python/plugins/LIRiAP/
- Windows:
-
Copy the plugin files: Create
LIRiAPfolder and copyLiRiAP_provider/andLIRiAP_pack/ -
Enable the plugin:
Plugins→Manage and Install Plugins→ find "LIRiAP" → enable -
Verify: Look for "LIRiAP" group in Processing Toolbox
- Open Processing Toolbox (
Ctrl+Alt+T) - Find algorithm (search or expand LIRiAP group)
- Select input layer, adjust parameters, click Run
- View results (output layer created)
Required: NumPy, SciPy, Shapely (typically included with QGIS)
Optional: Numba for JIT acceleration: pip install numba
Or enable AUTO_INSTALL_NUMBA in algorithm settings.
Algorithms not appearing:
- Verify folder location
- Check Log Messages panel (
View→Panels→Log Messages→Python)
"Module not found": pip install numpy scipy shapely numba
