Notes on data, analysis and

Original shapefile was derived from the 1:100 000 cadastral compilation map sheets series as supplied by the Ministry of

 

compilation:

Survey and Mapping. The following Map Projection was used in the capture (by digitising) of the farms:

 

 

 

 

 

Projection System : Modified Gauss Conformal

 

 

Unit of length : German legal meter. (1 GM = 1.0000135965 m)

 

 

Zone width : 2 degrees (Central meridians covering Namibia are: E13, E15, E17, E19, E21, E23, E25)

 

 

Scale factor on central meridian is 1.

 

 

Ellipsoid: Bessel 1841

 

 

 

 

 

The farms were classified into the Geographical Database using the key structure as prescribed by the Ministry of Survey

 

 

and Mapping. The positional accuracy is between 50m and 250m.

 

 

The original dataset of QGIS now belongs to DSM. Several versions are in existence which are identical in terms of

 

 

shapes/boundaries but which have additional or revised attribute fields (e.g. Ministry of Agriculture, Water and Rural

 

 

Development (Marina Coetzee) have a version (and copyright) with ownership up to date to 1998 from the Deeds

 

 

Office).
