Common Analytical Framework (CAF) Space

What is it?
CAF Space is a geo‑processing tool for transport planners that helps translate data between different zoning systems. It creates standard weighting and correspondence files so data can be consistently compared and analysed across different spatial boundaries. The open‑source Python tool supports simple spatial matching as well as weighted translations using data such as population or employment.

How is it useful?
CAF Space helps modellers, planners and GIS specialists carry out consistent spatial analysis for modelling, local decision‑making and funding business cases. By standardising how data is translated between zones, it reduces duplication, improves accuracy and supports clearer, more robust evidence to inform transport planning and investment decisions.
