osmosis-nls-dem is an @Osmosis plugin for adding height information to OSM nodes based on open digital elevation model (DEM) data from National Land Survey (NLS) of Finland.
The plugin requires The Java Advanced Imaging API (JAI) and Image I/O to work with .tiff-files. The installation instructions can be seen here or [here](JAI install guide).
To build osmosis-nls-dem from source, run:
git clone https://github.com/jsimomaa/osmosis-nls-dem.git
cd osmosis-nls-dem
mvn install
You can find the built JAR from osmosis-nls-dem/target/osmosis-nls-dem-${version}.jar
To install the plugin into Osmosis just copy the JAR in ~/.openstreetmap/osmosis/plugins/ and you are ready to go.
You can reference the plugin in your workflow with the nls-dem alias.
