North Kenya Vegetation GIS Database
Listed in NASA Earthdata CMR
New-ID: NBI160 FILE NAME NKVEGE.E00 Introduction The North Kenya GIS Database project was created by joining datasets which existed in 9 north kenya districts by Andrea Bottcher for GTZ at UNEP/GRID in 1996.
Description
The original datasets were derived from the Range Management Handbook published by the ministry of Agriculture in 1982. This handbook focused on the high and medium rainfall districts with good commercial and farming conditions.
Later the implementation of a Project to produce a Range Managment Handbook for the arid and semi-arid areas of the country was decided. The geographical extent of the dataset covers the following 9 ASAL( Arid and Semi Arid Land) Districts: - Baringo with approximately 11.000 sq.km. - Elgeyo Marakwet with about 2.800 sq.km. - Isiolo with appr. 26.000 sq.km. - Mandera with about 26.470 sq.km. - Marsabit with appr. 75.000 sq.km. - Samburu with appr. 20.000 sq.km. - Turkana with appr. 65.000 sq.km. - Wajir with about 56.500 sq.km. - West Pokot 9 100 sq.km.

The final datasets consist of 19 themes namely; - Districts Borders - Towns - Roads - Dense bush - Forest areas - National Park Boundaries - Special Surfaces (surfacial lava ) - Cliffs and Craters - Seasonal Rivers - Land Elevation Contours (Ft) - Marsh and Swamps - Productive risk due to lacking rainfall for the Districts Marsabit, Mandera, Wajir, Samburu, Isiolo - Median annual rainfall - Landforms and Soils - Landforms and Soils , generalized version - Vegetation - Range Units - Run-off zones - Waterpoints The source dataset were digitized by DRSRS (Department of Resourse Surveys and Remote Sensing) P.O. Box 47146, Nairobi The base information from which the original dataset were compiled were obtained through a variety of sources and medhodology, namely; a) field survey b) satellite images c) topographic maps d) aerial photographs e) district reports f) aerial observations from a low flying aircraft. f. existing previous studies
