CircuitscapeQGIS

By Marco Birkedahl Jørgensen

CircuitscapeQGIS is a QGIS plugin that integrates Circuitscape functionality for landscape connectivity analysis directly into QGIS. It supports resistance rasters, focal points, background task processing and multiple solver options.

Goals

• Provide a simple, reproducible interface to run Circuitscape from within QGIS.
• Support common workflows: resistance rasters, focal points, and export of current maps.
• Offer robust background processing and automatic CRS handling for focal layers.

Key Features

• Run Circuitscape in resistance or conductance mode.
• Background processing with the QGIS Task Manager.
• Automatic CRS transformation for focal points.
• Multiple solver options (fast AMG, precise CHOLMOD).
• Convenient export options (ASCII raster for downstream tools).

Usage Notes

Load a resistance raster and (optionally) focal points in QGIS, open the CircuitscapeQGIS plugin, configure inputs and solver, and run. Monitor progress in the QGIS Task Manager — outputs will be added to the map when complete.
