2009년부터 캐나다 농업식품부 (AAFC)의 과학기술부 (STB) 지구 관측팀은 연간 작물 유형 디지털 지도를 생성하는 과정을 시작했습니다. 2009년과 2010년에 Prairie Provinces에 초점을 맞춰 광학 (Landsat-5, AWiFS, DMC) 및 레이더 (Radarsat-2) 기반 위성 이미지를 사용하여 의사결정 트리 (DT) 기반 방법론을 적용했습니다. 2011년 재배 시즌부터 이 활동은 전국 작물 인벤토리를 지원하기 위해 다른 주로 확대되었습니다.
현재까지 이 접근 방식을 사용하면 최종 공간 해상도 30m (2009년과 2010년에는 56m)에서 전체 목표 정확도 85% 이상을 충족하는 작물 인벤토리를 일관되게 제공할 수 있습니다.
