We are progressing well with the TerraClim project, and major milestone in the efficiency and accuracy of interpolations.
The regional interpolation analysis divided the Western Cape study area into smaller regions using the local terrain and climatic characteristics of that particular region. The regionalisation of temperature interpolation showed improved accuracy of spatial interpolations by up to 0.8ºC and resulted in a 30% to 50% reduction in the processing time to serve locally tailored temperature layers for approximately 97.9% of vineyards in the Western Cape. Regionalisation enables modularity; thus, the new study area can easily be expanded in the future to aid decision making to farm and field level.
