For large areas, it is difficult to assess the spatial distribution and inter-annual variation of crop acreages through field surveys. Such information, however, is of great value for governments, land managers, planning authorities, commodity traders and environmental scientists. Time series of coarse resolution imagery offer the advantage of global coverage at low costs, and are therefore sui...

Acreage estimates are crucial for forecasting menthol mint acreage, as crop output figures fluctuate from year to in response fluctuations the market price of oil. Thus, there yearly maximum that farmers can obtain. Since low production arises rates, and high results prices, these acreage estimate studies may be useful lowering uncertainty regarding mints’ output. The widespread adoption remote...

This study presents a crop planting and type proportion (CPTP) method for crop acreage estimation of complex and diverse agricultural landscapes. CPTP has three major components: (1) Crop planting proportion (CPP), estimated with wide-swath satellite remote sensing data to completely cover the monitoring area by segmenting cropped and non-cropped areas through unsupervised classification. (2) C...
