FIGURE 2. The TerraClim platform presents high resolution temperature maps, the unique adaptive colours tab when enabled, adjusts the colour ramp (and legend) to the area being viewed within the extent of the viewing window. This provides a more detailed spatial description of temperature changes at field level for a specific day and/or hour.

to this data, but there are few attempts to integrate technologies, as well as to roll it out into the wine industry. The study outcomes integrated with TerraClim have and continue to provide new data sources for future research in the field of high resolution spatial and temporal resolution climate and remote sensing data specific to the wine industry. What sets TerraClim apart in the growing

relationship of environmental factors and terrain elements (figure 4). The integration of 2 m terrain derivatives with high density of hourly data points through automated real-time workflows will provide the project with new research outcomes for method improvements. TerraClim continues to develop efficient techniques for producing accurate, high resolution climate surfaces (including

rainfall, humidity and wind) covering the entire Western Cape province, and to expand the functionality of the TerraClim webapp (www.terraclim.co.za), including an interactive reporting system, query functionality and crop suitability analysis. KEY TAKE-HOME MESSAGE In the context of cultivar adaptation to a changing environment, new economic challenges in wine grape production, as well

as expanding viticultural areas in South Africa, a need exists to integrate agro- climatology with geographic information systems (GIS), as well as remote-sensing technologies currently available (figure 1). To this end, data capturing, processing and system development to implement data visualisation to consultants and industry role players are crucial aspects. Currently there are many sources of data, as well as models being developed to add value
