Effective correction of remotely sensed data for terrain illumination effects over mountainous areas, requires Digital Elevation Model (DEM) data at an appropriate resolution and quality. Conversely, the performance of terrain illumination correction and scale-based analysis could be used to evaluate the quality of DEM data used for the correction. In this study, TanDEM-X Intermediate DEM (IDEM) data at 12 m resolution and the 1-arc second Shuttle Radar Topography Mission (SRTM) data were used independently to evaluate the relative effectiveness of the terrain illumination correction for Landsat 8 optical data over Tasmania, Australia. Results from the terrain illumination correction and filter bank analysis show that IDEM 12 m data can resolve finer details of terrain shading than the SRTM based DEM and deliver better results in areas with detail-rich terrain. However, in the data available for this study, spikes and other noise artefacts were prevalent, especially over areas covered by water; removal of such noise artefacts would increase the utility of the IDEM for operational correction of terrain illumination effects in optical satellite data.
