Urban Monitor

Urban Monitor (UM) provides mapped data of the urban tree canopy for the Perth and Peel Regions in Western Australia under the Better Urban Forest program.

Using four-band aerial imagery, vegetation height has been calculated and reported for each height strata of 0–3 metres, 3–8 metres, 8–15 metres and 15+ metres.

Core products include digital ortho-photo, vegetation cover, vegetation vigour, vegetation height, ground elevation, surface elevation and a combination of the above through a normalised elevation model and vegetation cover to achieve the layers of grass, trees and shrubs.

The UM products were developed by the Data 61 team at the CSIRO for the Department of Planning, Lands and Heritage (DPLH) on behalf of the Western Australian Planning Commission (WAPC)

The Urban Growth Monitor is a component of the DPLH's Urban Development Program for the WAPC to fulfil its requirements for tracking and modelling land supply as outlined in the Planning and Development Act 2005.

Capture of aerial photos, web-map services, coordination of the consortium and distribution of UM products is done by Landgate.
