The Heard Island, Laurens Peninsula, Topographic Data was mapped from Ortho-rectified non-metric photography. The data consists of Coastline, Crater, Volcano, Island, Lagoon, Water Storage and Watercourse datasets digitised from the photography.
Topographic features in the Heard Island, Laurens Peninsula, Coastal Area were mapped by a photogrammetrist from the ortho-rectified image mosaic described in photo_mosaic_laurens_or. The features were mapped using Erdas 8.7 and ArcView 8.3. The photography only covered coastal regions. Photography was taken using a non-metric camera and the data was rectified using GPS ground control and a ... small scale Radarsat DEM. The calibration details of the camera were unknown. Any additional topographic features mapped as part of the vegetation mapping project described in photo_mosaic_laurens_or_VegMapping which were not initially mapped were included in the topographic dataset. The digitised data was then imported into Arc/Info coverage format and topology was created. The data is attributed according to the SCAR Feature Catalogue.
