Alternate Titles

  • Formerly known as ‘Geoscape’.

  • Trees for Australia

Abstract

Trees is a raster dataset representing tree coverage and heights across Australia, derived from remotely sensed data.

Description

The Trees theme consists of a single Trees layer. The Trees layer consists of a digital pixel representation tree coverage and their associated heights derived through DEMs. The Theme is comprised of pre-defined urban areas at a two-metre resolution. The distribution corresponds to the Tree type pixel in the Urban Surface Cover product.

Data quality and potential capture timelines will vary across Australia based on three categories. Each category has been developed based on several factors defined by the population distribution (categorised based on population size), industrial/commercial activities, the probability of natural events (e.g. flooding) and the image source.

  • Urban (satellite source) - areas with a population greater than 200, or with significant industrial/commercial activity in a visual assessment, digitised from satellite imagery

  • Urban (aerial source) - areas with a population greater than 200, or with significant industrial/commercial activity in a visual assessment, digitised from aerial imagery

  • Rural - all other areas

Purpose

The purpose of the Trees is to spatially represent tree coverage and tree heights for use by industry and government in geographic information systems and/or other information systems.

Topic Category

Raster spatial data.

Geographic Description

The spatial coverage of Trees includes Australia’s land mass. The Bounding Box for this data is as follows:

  • North bounding latitude: -9˚

  • South bounding latitude: -44˚

  • East bounding longitude: 160˚

  • West bounding longitude: 100˚
