Urban Monitor (UM) is a four-band aerial photography monitoring system, based on consistent data and methods that are able to track and communicate changes in features of interest in a way that has previously not been possible. The UM initiative has included partners (UM consortium) with responsibility for management of vegetation, river and wetland environments, and scheme and self-supply water resources.

Core products are a 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, and trees and shrubs. Still in development are new products such as change detection and change analysis. The UM products were developed by CSIRO in conjunction with user requirements from these consortium members. Capture of aerial photos, web-map services, coordination of the consortium and distribution of UM products is done by Landgate.
