This paper presents results of a comparative study of the vegetation-caused elevation bias of the space shuttle topographic mission data product, both C- and X-band (SRTM.C/X). The SRTM.C/X bands data were compared against a high-resolution digital terrain model and discussed. As a test site, an area on the Gold Coast, Queensland, Australia, was selected. This area is covered by vegetation varying from grassland and shrubs to forest. The study method allowed the development of a statistical model relating the elevation bias to the percentage of the vegetation cover of a given land parcel. This model, once verified on varieties of vegetation types, could be utilised to estimate and eliminate the elevation bias from the InSAR elevation model
