A plugin for displaying geodata stored in a geojson format as a layer in JOSM.
You need to have Java 8 or later installed.
Then run
./gradlew buildRun
./gradlew runJosmYou do not need to build first, Gradle will check if you already built the current state of the source code and if not, it will build it for you on the fly.
You also do not need to have JOSM installed. The version of JOSM that is firing up is independent of any installed JOSM versions and uses a different JOSM_HOME directory than other JOSM installations.
To open a *.json or *.geojson file, File > Open, select the file, and to make the list appear, click Windows > Geojson
Run
./gradlew eclipseThen import the project as "Already existing project" and all should be set up.
Have fun 👍 🎉
