In 1995 a forest inventory covering northern Namibia was initiated, based on stratified systematic field sampling of plots with a radius of up to 30 m. In these plots detailed tree parameters were measured. Due to security problems the most important wooded parts of the area could not be covered. This study investigated whether Landsat TM imagery could be used to estimate woody vegetation parameters. Keywords: remote sensing, forestry, tree coner, tree biomass, tree volume, Kalahari woodland.
