Abstract
This paper presents results of exploring options for a three dimensional visualization based upon data quality assessment using digital photogrammetry and GIS technology. In support of terrain visualisation for landform evolution study of the Southern Range, Tasmania, topographic data and annotated aerial photography are processed. The interpolated digital elevation model (DEM) is assessed through statistical analysis and visualization and the orthorectified image is evaluated empirically for the glaciated cirque terrain. Raster based DEM generation is more satisfactory when some TIN functionality is deployed and the ortho‐image mosaic is preferred when using features with higher relative accuracy. The procedure of the assessment is rather practical and efficient as has been shown in the geomorphologic application.
