Existing crop yield models typically estimate paddock-scale yields across small areas, or regional-scale yields nationally. This dichotomy restricts our ability to scale between paddock, region and country yields. We developed a nation-wide, paddock-scale crop yield model based on satellite imagery, called CCrop. For its simplicity, C-Crop is effective at estimating canola and wheat yields, with about 70% accuracy. Ongoing model refinements will improve accuracy, encompass more crop types and perform mid-season forecasting. Coupled with crop type maps, C-Crop now provides the ability to conduct nation-wide, fine-scale monitoring of Australian grain production.
