5.32 THE SIZES OF FREEHOLD FARMS - FARMS MAP |

Description: |
Map of all freehold farms in Namibia |
Chapter: |
5 Land and History |
File name: |
farms |
File type: |

Geographical area: |
Namibia |
Keywords: |

|
freehold |
|
commercial |
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). |
