Hey Craig, why not simply expose the geohash via the opennms rest api. This would allow you to use the build in plugins.
The change should be applied to the OnmsGeolocation object: https://github.com/OpenNMS/opennms/blob/9753e6af616828c62fefae0cbc5c3dc58c09b02f/opennms-model/src/main/java/org/opennms/netmgt/model/OnmsGeolocation.java <https://github.com/OpenNMS/opennms/blob/9753e6af616828c62fefae0cbc5c3dc58c09b02f/opennms-model/src/main/java/org/opennms/netmgt/model/OnmsGeolocation.java> I’d use this 3rd party API to generate the geohash: https://github.com/davidmoten/geo <https://github.com/davidmoten/geo> http://davidmoten.github.io/geo/apidocs/index.html <http://davidmoten.github.io/geo/apidocs/index.html> -> Geocode.encodeHash(double, double) The change is probably something like this: @XmlTransient @Transient public String asGeoHash() { if (m_longitude != null && m_latitude != null) { return Geocode.encodeHash(m_latitude, m_longitude); } return null; } Kind regards - Markus > On 19.
