Data Updates and Maintenance

Geoscape completed delivery of the national Trees product in October 2018 and has since commenced the update, maintenance and improvement program. More information on the proposed update schedule is available from the Geoscape website.

Update Frequency

Updates to Trees are applied and released on a quarterly schedule.

Update Source

The initial capture of the Trees layer was classified from remotely sensed satellite imagery at a 2-metre grid resolution. From the November 2021 product release, updates to Trees have been classified from aerial captured imagery and DEM processing.

Update Scope

Trees updates occur for all existing objects with changed geometry, attributes and/or metadata, as well as data for new objects supplied prior to the release time period. Updates to the product include:

1. The inclusion of any new capture of Trees data received from third-party partners.

2. Corrections and/or improvements to production processes in generating Trees.
