Why it matters?

‍

CliffMetrics for Linux matters because running cliff‑top and cliff‑toe extraction at national scale requires a workflow that is fast, repeatable, and able to run on high‑performance computing systems. While the SAGA GIS version of CliffMetrics can be automated through the SAGA terminal, very large areas quickly push beyond what a desktop setup can handle. The Linux version was created to solve this problem: it lets users run CliffMetrics programmatically, efficiently, and in parallel on clusters and HPC environments where Linux is the standard operating system. This makes it possible to process thousands of kilometres of coastline in a consistent, transparent way — a capability that is essential for national assessments and long‑term coastal planning.
