Abstract
The Nogoa River catchment in the Fitzroy Basin is a very significant contributor to the Queensland economy. The topographical complexity of this catchment requires efficient and effective management of the environment to sustain both economic and ecological benefits. Information on terrain shape and drainage structure is important in developing sustainable management practices. This paper outlines the methods used and the challenges faced during the development of a Digital Elevation Model (DEM) for the Nogoa River catchment. It is also intended to assist those involved in DEM creation to understand potential problems and to plan ahead to maximise efficiency.
