LarvaLink QGIS 4 compatibility
Not QGIS 4 ready Active
Not yet — the latest version declares max QGIS version 3.99.0, so it is not offered to QGIS 4 users.
Visualize spatial connectivity matrices
About
LarvaLink visualizes source and sink strength from spatial connectivity matrices and updates those metrics interactively for selected polygon features. On first load it adds numeric fields src and snk to the active layer when missing, then drives graduated symbology from them. Requires NumPy in the QGIS Python environment (bundled with standard QGIS installers on Windows and macOS; on Linux, install python3-numpy for your QGIS Python if needed).
