Comparison between sensors with different spectral resolutions, relative to the sumbandila satellite, for assessing site quality differences, in eucalyptus grandis plantations

Author: Main, Russell S ; Cho, Moses A ; Van Aardt, J ; Majeke, B Date: Oct 2008 The majority of earth observation studies have for years made use of data from multispectral spaceborne sensors. More recently though, both airborne and spaceborne narrowband hyperspectral sensors have come to the fore and are able to provide ... Read more
Extracting structural land cover components using small-footprint waveform LDAR data

Author: McGlinchy, J ; Van Aardt, J ; Rhody, H ; Kerekes, J ; Ientiluci, E ; Asner, GP ; Knapp, D ; Mathieu, Renaud SA ; Kennedy-Bowdoin, T ; Erasmus, BFN ; Wessels, Konrad J ; Smit, IPJ ; Wu, J ; Sarrazin, D Date: Jul 2010 Previous work has shown the ability of waveform LiDAR sensors to accurately describe various land cover types and biomass estimates made in the field. What is lacking, however, is a way to describe the different structural components that are ... Read more
Integrating remote sensing and ancillary data for regional ecosystem assessment: eucalyptus grandis agro-system in kwazulu-Natal, South Africa

Author: Cho, Moses A ; Van Aardt, J ; Main, Russell S ; Majeke, B ; Mathieu, Renaud SA ; Norris-Rogers, M ; Du Plessis, M ; Ramoelo, Abel Date: Jul 2009 The study demonstrates that the integration of remote sensing and in situ data could be important in providing more accurate estimates of E. grandis state in KwaZulu Natal, South Africa compared to remote sensing models. Such modelling effort ... Read more
Land degradation mapping for modelling of ecosystem benefit flows in the Inkomati catchment using remote sensing.

Author: Ramoelo, Abel ; Munyati, C ; Lück-Vogel, Melanie ; Le Maitre, David C ; Van Aardt, J Date: Sep 2007 Land degradation is of great concern in South Africa particularly in the Inkomati catchment. Here a mosaic of different land use types such as plantation agriculture, subsistence farming, irrigated commercial farming, rural and urban settlements, ... Read more
Medium resolution image fusion, does it enhance forest structure assessment

Author: Roberts, JW ; Van Aardt, J ; Ahmed, FB Date: Jul 2008 This research explored the potential benefits of fusing optical and Synthetic Aperture Radar (SAR) medium resolution satellite-borne sensor data for forest structural assessment. Image fusion was applied as a means of retaining disparate data ... Read more
Spectral variability within species and its effects on savanna tree species discrimination

Author: Cho, Moses A ; Debba, Pravesh ; Mathieu, Renaud SA ; Van Aardt, J ; Asner, G ; Naidoo, Laven ; Main, Russell S Date: Jul 2009 Differences in within-species phenology and structure driven by factors including topography, edaphic properties, and climatic variables present important challenges for species differentiation with remote sensing in the Kruger National Park, ...

Three-dimensional woody vegetation structure across different land-use types and land-use intensities in a semi-arid savanna

Author: Fisher, J ; Erasmus, BFN ; Witkowski, E ; Van Aardt, J ; Asner, G ; Kennedy-Bowdoin, TY ; Knapp, D ; Mathieu, Renaud SA ; Wessels, Konrad J Date: Jul 2009 Factors influencing woody savanna vegetation structure across a land-use gradient of intensity (highly and lightly utilized communal rangeland) and type (national protected area, private game reserve and communal rangelands) were investigated. ...
