TL;DR: In this article, an automated cropland mapping algorithm (ACMA) was used to capture extensive knowledge on the croplands of Africa available through ground-based training samples, very high (sub-meter to five-meter) resolution imagery (VHRI), and local knowledge captured during field visits and/or sourced from country reports and literature.
Journal ArticleDOI
Spectral matching techniques (SMTs) and automated cropland classification algorithms (ACCAs) for mapping croplands of Australia using MODIS 250-m time-series (2000–2015) data

TL;DR: The extent and vigor of the Australian croplands versus cropland fallows were accurately captured by the ACCA algorithm for the years 2000–2015, thus highlighting the value of the study in food security analysis.
