Geosense completes Vineyard acquisition program in Western Cape

Cape Town, April 21, 2011 – Getmapping subsidiary Geosense, in partnership with Precision Surveys has just completed a successful aerial and ground based acquisition program in the Western Cape focused primarily on the wine producing regions. The program undertaken during February and March of this year captured over 130,000 hectares of vineyards including farms in CapeTown, Hermanus, Grabouw, Stellenbosch, Franschoek and Piketberg.

The program provides Viticulturists with true colour and colour infrared orthorectified imagery as well as a normalised difference vegetation index (NDVI) map at high resolution (25cm Ground Sampled Distance). These are used as tools to assess the quality of the vines pre-veraison (prior to ripening).
