Abstract:
Distribution and description of different vegetation unit with associated information on biomass, species composition and vegetation index from NDVI. The data set covers the entire Namibia. The data is produced at Okaukweyo and is distributed to different offices in the country where various research are being carried out.

Positional Accuracy: 500M
Measuring Units: Meters
Sampling and Analysis standards: According to standard NDVI equations
Frequency of sampling: Daily
 
Purpose:
The data set is primarirly used to monitor Vegetation Dynamics in Namibia.

Staffing Situation: at the moment (June 2002), the processing software is broken and the processing/Whole process has been has been in break since 2001 April. This is the first time a break occur since 1994 and this does not effect the fitness for data use. Only breaks the Satelite Image Capturing.
