ABSTRACT
ABSTRACT: High spatial resolution images of multi-spectral digital TETRACAM camera were used to map vegetation for upscaling transpiration from tree-bush-shrub of Serowe, Botswana. The camera was mounted on a small aircraft to collect data in 30, 60 and 100cm spatial resolution. The results were compared with one-meter improved multispectral IKONOS satellite images. The high resolution airborne images show high potential for mapping tree-bushy-shrubby vegetation of the study area for up-scaling transpiration. The spectral characteristics of the high spatial resolution images are similar to IKONOS satellite images, while the spatial characteristics of the high spatial resolution images are much better than the one-meter MS IKONOS satellite images.
