MaplatTransform Wiki

Welcome to the MaplatTransform Wiki. This is the long-form reading area for the project — tutorials, concept articles, FAQ, and gallery live here.

MaplatTransform is the runtime coordinate-transform engine of the Maplat ecosystem. It takes compiled TIN definitions (produced by @maplat/tin) and performs bidirectional, topology-preserving transformation between two plane coordinate systems, including sub-map selection, viewport transformation, and cross-map viewport synchronization.

For the latest install steps, version info, badges, and license, please see the README first. This Wiki holds the release-independent material that grows between releases (ADR-0012).
