Heard Island Topographic Mapping from Orthophotos derived from Non-Metric PhotographyEntry ID: HIC_PHOTO_NMOrtho_TopoMapping
Abstract: The Heard Island Topographic Data was mapped from Ortho-rectified non-metric photography. The data consists of Coastline, Glacier, Lagoon, Offshore Rocks, Water Storage and Watercourse datasets digitised from the photography, all of which are available for download at the url given below.

Quality Topographic features in the Heard Island Coastal Area were mapped by a photogrammetrist from the ortho-rectified imagery described in the metadata record &Heard Island Coastal Orthophotos derived from Non-Metric Photography& (ID - HIC_NMOrthos).
The features were mapped using Erdas 8.5 and ArcView 8.1. The photography only covered coastal regions and excluded glaciers. ... Photography was taken using a non-metric camera and the data were 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 HIC_NMOrtho_VegMapping which were not initially mapped were included in the topographic dataset.
The digitised data were then imported into Arc/Info coverage format and topology was created. The data are attributed according to the Feature Catalogue.
