GFSAD 250m Cropland Products of Australia Automated Cropland Classification Algorithm (ACCA)

U.S. Geological SurveyU.S. Department of Interior

Based on Ideal spectral signatures, developed

Automated Cropland Classification Algorithm (ACCA) for

each of 3 cropland masks of Australia.

Validated ACCA-2014 results with SMT-2014 results

Applied ACCA year to year (2000-2014) to study

cropland change dynamics over 15 years
