•  Administrative Boundaries

The legend of the new maps includes International boundaries, region boundaries (there are 13 administrative regions in Namibia ), limits of constituencies, townlands and controlled area (having limited accessibility, like the diamond areas in the south). The cadastral limits of farms are included, but not the cadastral parcels (“erven”) in urban areas. The limits of national parks and reserves are also indicated on the topographic map.

Some boundaries have a hierarchical organisation: constituencies are always fully included in one and only one region, region boundaries strictly correspond to the limit of the Country, etc.

Accordingly, it is not necessary to represent 2 or 3 superposed limits, and only the highest level is represented.

Unfortunately, more than one third of all international borders in Africa are in various degrees of dispute and Namibia is no exception to this. When an official document describing the border was available, it was used for mapping. In many cases however, the position of borders should be considered only as an indication, and are not authoritative.

Region and constituency names are indicated in some places along the limits. If a line is shared between a region limit and a constituency limit, both names will be indicated, using different font sizes. If an administrative limit match the edge of a map sheet, the limit is indicated along the frame of the map, with corresponding names. If only names are placed along the frame, this means that the region / constituency does not stop at the edge of the map.

Limits of parks and reserve are differently organised and do not necessarily correspond to administrative limits. Accordingly, when a limit of a park / reserve corresponds to an administrative limit, both are indicated (the limit of the park is them slightly moved to avoid overlapping lines).

Many administrative limits correspond to other elements of the landscape such as roads and rivers. In such situation, the road or river is displayed at is actual position of the map, and the administrative limit is slightly moved on one side of this feature, to allow a better reading of both elements. This indirectly means that the position of these limits on the map are not always accurate, and shouldn't in any case be used as and official reference (an offset of 2mm on a 1:250'000 map corresponds to 500m on the ground !).

In some area, the density of private farm boundaries is very high. To simplify the map, some farm boundaries matching roads and rivers are simply not displayed.
