The second part of the project, carried out by the United
Kingdom team included mainly identification of all
vegetation types within the particular polygons and other
thematic information from panchromatic photographs,
initial and final field verification within the project area,
digitizing of all features from the original map and the new
overlay and processing and analysis of all geometric
information with the corresponding thematic data with
ARC\INFO, to obtain the final results. The classification
and analysis process was concerned with incorporation of
13 vegetation classes and 9 non-vegetation classes into the
habitat coverage [Cassels, 1994]. The vegetation classes
were selected as follows; 1 - Miombo Woodland, 2 -
Munga Woodland, 3 - Chipya Woodland, 4 - Chitemene
Woodland & scrub, 6 - Riverine Fringing Forest, 7 -
Mushitu Swamp Forest, 8 - Mateshi Dry Forest, 11 -
Seasonally Wet Grassland, 12 - Seasonally Wet
Grassland/Termitaria, 16 - Bush Group, 17 - March or
Swamp, 18 - Papyrus Swamp, 33 - Cultivation. The other
classes were concerned with water, geology, roads and
settlements.
Examples of the graphic outputs showing combination of
various vegetation coverages are presented in figure 3, (a) -
classes 1,2,3,4, (b) - classes 6,7,11,12,16,17, (c) - class 33.
Rivers and other water bodies are shown in figure 3 (d).
4. CONCLUSION
The use of simple photogrammetric methods concerning
field control densification and mapping of vegetation
boundaries and other features in area of the Kasanka
National Park and surrounding Kafinda Game
Management Area in Zambia allowed to create a GIS data
base at low cost and within short time. Both, the cost and
the time were at least a half of those needed for
conventional methods of aerial triangulation and mapping.

Such simple photogrammetric methods can be
recommended for mapping other national parks of large
areas in Africa.
The project has delivered the initial information, in a form
of the GIS data base, on habitat in the project area. The
subsequent research related to wildlife management in this
Park will be greatly enhanced with the availability of these
data. The new types of information and the changes in
time to the Park habitats caused by fire, weather, firewood
collection, grass cutting, movement of wild animals,
poaching, fishing and other, can be examined and
introduced to the basic GIS data base. This allows the
control of overall wildlife resources and their changes.
