Abstract

1. Using colour aerial photography, a set of fine spatial resolution orthomosaics and accompanying Digital Elevation Models (DEMs) were generated for the majority of mangroves in Kakadu National Park, Northern Australia, from which their extent and canopy height have been mapped.2. the orthomosaics and DEMs, which were based on 68 sterio pairs acquired in 1991, cover an area of approximately 742km2 and a coastal distance of 86 kms. The DEMs have a height resolution of approximately +-1m.3. The entire mosaic represents a key historical baseline data set of the extent and height of mangroves within the Park against which to observe and quantify changes in response to, for example, sea-level rise.4. The data sets will be available to assist management of the coastal environment and also to provide a unique insight into the distribution, dynamics and consition of mangroves. the techniques used are applicable to managroves and other forested wetlands in other regions of Australia and elsewhere.
