1. Overview

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.

  • 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).

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.
