Brief description
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:
Vegetation - Species/Ground Cover Types
Code - Species/ground cover types
AM - Acaena magellanica
AS - Azorella selago
CA - Callitriche
CA w/ H2O - Callitriche in water
CO - Colobanthus sp.
DE - Deschampsia
G - Gravel
L - Lichen
LI - Liverwort
M - Moss/Bryophytes
MO - Montia fontana
PA - Pringlea antiscorbutica
PAN - Poa annua
PC - Poa cookii
PK - Poa kuerguelensis
PK/PC - P. kerguelensis / P. cookii Hybrid
R - rock
S - sand / soil
W - Water
Vegetation - Communities / Associations
Code - Community
DCC - Closed Cushionfield
DCC w/ Aceana - Closed Cushionfield with Aceana
