Abstract

A detailed structure and composition dataset has been assembled for a 200m x 200m area surrounding the eddy covariance flux measurement tower near Skukuza in the Kruger National Park. The information includes (by species) individual stem mapping, biomass and leaf area, canopy cover and height. Several different techniques were used for most of the attribute estimates, allowing a comparison of methods and an estimation of their accuracy. At the same time that the in situ information was collected (April 2008) using manual, photographic and ground-based laser scanning techniques, hyperspectral reflectance and lidar canopy structure information was gathered at 0.5 m resolution for this patch and a larger surrounding area, using the Carnegie Airborne Observatory sensors. The site has a nine-year record of water, energy and CO2 fluxes, phenology and various other ecological measurements. Initial findings relating to measurement techniques and basic structural parameters for the site are presented. The intention is to make the data available as a standard calibration site for remotely sensed products.
