This dataset consists of Hyperion satellite imagery, as well as GPS ground truthing of vegetation quadrats.
The aims of this project were:
1. to produce a spectral library of the major subantarctic terrestrial plant species and community types from ground spectroradiometery measurements .
2. to use the spectral library to assist in classification of vegetation communities.

Table of vegetation data collected from Heard Island in the summer of 2003-2004 by Johanna Turnbull. Areas surveyed were Paddick Valley, Fairchild Beach, Dovers Moraine and Skua Beach. Ten 1x1 m quadrats were sampled with each 30x30 m site surveyed. Quadrats were selected haphazardly. Numbers are given as percentage cover of each species, averaged out over the ten sampled quadrats, unless otherwise stated.
The Codes used for species/ground cover types and vegetation communities/associations can be found in sheet 2 of the excel file, called &vegetation codes&. They are also listed below:
