KTS — a Kotlin Multiplatform port of JTS 1.20.0

[mipastgt]

I'd like to share KTS, a faithful Kotlin Multiplatform port of JTS 1.20.0 that I've just published:

• Repo: https://github.com/mipastgt/kts
• Maven Central: group de.mpmediasoft.kts, version 1.20.0.0

It's a language port, not a fork or redesign — the goal is behaviour identical to upstream, keeping the same public types and the original org.locationtech.jts.* package names, so existing JTS knowledge and docs carry over directly. To keep it honest, the Kotlin is compiled against JTS's own unmodified Java test suite (2100+ tests) as its reference.

Targets: JVM (Java 8+), JS (Node/browser), Wasm/JS, and Kotlin/Native (macOS, iOS, Linux, Windows).

Modular packaging: kts-core (geometry model, predicates, overlay, buffer, algorithms, WKT/WKB writers) plus à-la-carte IO modules kts-io-wkt, kts-io-gml, kts-io-kml, kts-io-geojson, kts-io-files.

The main deliberate deviations from upstream are documented in the repo: IO readers split into kts-io-* modules, GeoJSON built on kotlinx-serialization, stream-based IO as JVM-only extensions, and the removal of JVM-only surface (java.io.Serializable, Cloneable, the awt package). Full list: KOTLIN-MP-COMPATIBILITY.md.

Huge thanks to the JTS maintainers and contributors — this port stands entirely on your work. Sharing it here in case it's useful to anyone needing JTS geometry outside the JVM.
