How it works
From the COMET cost surface to the priced route — concepts first, then the workflow tab by tab, then reference tables.
Getting started
- IntroductionWhat CO2GIS is, the problem it solves, and who it's for.
- InstallationHow to install CO2GIS in QGIS — from the Plugin Manager or from a ZIP file.
- Sample dataReady-to-use datasets for testing the plugin — the same sources used in the original research for Portugal Continental.
- The 7-tab workflowHow the tabs chain together — each one's output feeds the next.
Concepts
The workflow
- Land Use (Flu)Turn a classified land-cover raster into the land-use cost factor.
- Slope (Fs)Derive a slope raster from a DEM, then turn it into the slope cost factor.
- Crossings (Fci & N)A crossing-cost raster and a per-cell count of crossed infrastructure.
- Corridors (Fc)Reward routing alongside existing corridors, with onshore/offshore handling.
- Aux (helpers)Utilities to prepare data and speed up processing. No cost output.
- LCP (the route)Combine the cost factors into one surface, then trace the least-cost route.
- Price Estimation (CAPEX)Estimate the route's capital cost from the cost rasters and flow parameters.

Networks (experimental)

- Using the featureStep-by-step workflow — enable, prepare inputs, choose an engine, run, read the output, and price the network.

- Network CAPEXHow a pipeline network is priced — per-segment sizing, spacing boosters, and junction boosters where flows merge.
