A segmentation approach to delineate zones for differential nitrogen intervention. Multi-source and -temporal data integration is expected to support the delineation of within-field management zones that may better conform to unique combinations of crop yield variations. This work a... ... Repository: BDPA Publication year: 2013
Global tropical forest cover change assessment with medium spatial satellite imagery using a systematic sample grid - data, methods and first results. At the Joint Research Centre (JRC) of the European Commission, a methodology has been developed to monitor the pan-tropical forest cover with remote sensing data for the years 1990-2000-2005 in Latin... ...
