It is essential to have accurate maps in any farming enterprise, particularly if you are planning to do precision farming.
Other times when you will be grateful to have maps are when you are:
- planning aerial crop-spraying
- determining the potential of land
- applying pesticides
- ordering seed and fertiliser
- wishing to insure your crops hiring or renting land
- when planning time periods for grazing
- having overhead installations done e.g. power cables
- estimating crop yields
- determining crop suitability
- searching for breeding stock
Geographical Information Systems (GIS), a system of synthesising information, uses maps and ortho rectified photography as inputs to generate data (ordinary photographs can lead to inaccuracies and GIS is about measurement). Other systems of mapping include the use of satellites and Topo-cadastral mapping.
Your nearest agribusiness (e.g. VKB or OVK) will be involved in mapping and Geographical Information System, helping you to access farm and regional maps. Find contact details on the “Agribusiness” page.

GIS: data processing (data capturing and projections); applications (crop modelling, spatial modelling / interpolation, multi-layer modelling); spatial database development (Informix, MS Access) and data integration
Satellite & Airborne Remote Sensing: low-level imaging (digital multispectral video camera, precision farming information); digital image processing (geo-referencing, image classification); image interpretation (vegetation mapping & monitoring – population dynamics, degradation mapping, rangeland ecology, savanna ecosystems, crop inventories, drought monitoring, land cover, soil mapping and conservation planning); sample frame statistics (area / point); disasters (flood mapping; drought monitoring; fire mapping).

Tel: 012 841 1911
A modern Drawing Office produces a wide variety of geoscientific maps using both conventional and electronic cartographic technologies. The production procedures are increasingly automated, linked to the ARC/INFO-based GIS, which facilitates rapid map production and updating. The CGS actively participates in a variety of SADC projects aimed at promoting the economic development of the African sub-continent.

Africa Land-Use Training http://alut.co.za
Africa Land-Use Training offers a four day course on basic farm planning. Learners who successfully complete this course should be able to:
- assess and collect data on natural resources on a farm;
- do basic map reading;
- draw a farm map showing land capability units;
- do a basic infrastructure development plan for a farm.
Some of the Agricultural Colleges do short course training in map reading along with practical exercises involved with the different lectures. Find their details in the “Agricultural education and training” chapter.
