WKT Parser for Geographic Data

verified May 27, 2026

The `wkt-parser` library provides robust parsing capabilities for Well-Known Text (WKT) and PROJJSON strings, designed specifically for geographic and geodetic data. Originating as a standalone component extracted from the `proj4js` library, it aims to offer a dedicated and hackable solution for WKT and PROJJSON interpretation. It supports both WKT1 and the more advanced WKT2 standards, alongside PROJJSON, a JSON representation for coordinate operation definitions. The current stable version is 1.5.5, with frequent updates indicated by its recent publish history. A key differentiator is its comprehensive support for multiple WKT standards and PROJJSON, making it versatile for applications dealing with various geospatial data formats. However, it explicitly notes limitations: it does not support geocentric coordinate systems (`GEOCCS`) and `COMPOUNDCS` is only partially supported for WKT1. This focus makes it a specialized tool for developers working with projection and coordinate system definitions.
