Data sources & licences

Dig Here combines government open data with our own terrain analysis. Where we modify source data (for example LiDAR → bare-earth DEM → SVF / openness / LRM layers), we note that below and attribute the original custodians. This page satisfies Creative Commons attribution requirements.

How to cite Dig Here terrain layers

When sharing screenshots or discussing a Dig Here map view, include the data custodian attribution shown on the map footer for the area you are viewing, plus a link to this page. Victorian LiDAR derivatives should reference CC BY-NC 4.0 until any separate commercial licence is in place.

Per-cluster licence metadata is stored in our pipeline manifests and laz_clusters index when patches are published to /map3.
