Spectral sampling of vegetation species in the wet dry tropics

摘要

A spectral database of land cover endmembers pertinent to remote sensing for minesite rehabilitation assessment is being developed, which includes exotic and native vegetation groundcovers. The purpose is to investigate the spectral response of the phenological condition when data was captured, and analyse the change in phenology both within and between species over time. Spectral data collated in the database may be used to determine the most appropriate sensor for assessing minesite rehabilitation at different times of the year. Standards for reflectance spectral measurements of temporal vegetation plots were developed and published, including protocols to acquire robust in situ data. Spectral sampling was undertaken over a two year period and selected results are presented.
