2020 Kuzey Amerika Kara Örtüsü 30 metrelik veri kümesi, Natural Resources Canada, United States Geological Survey ve Ulusal İstatistik ve Coğrafya Enstitüsü de dahil olmak üzere üç Meksika kuruluşu arasındaki üçlü bir çalışma olan Kuzey Amerika Kara Değişikliği İzleme Sistemi (NALCMS) kapsamında üretildi.
NLCD (Ulusal Arazi Örtüsü Veritabanı), 8 döneme (2001, 2004, 2006, 2008, 2011, 2013, 2016 ve 2019) yayılan, Landsat tabanlı 30 metrelik bir arazi örtüsü veritabanıdır. 2021 için dokuzuncu bir dönem de burada mevcuttur. Görüntüler, kentsel alan için geçirimsizlik veri katmanına dayanır.
ABD Yerbilimsel Araştırma Kurumu (USGS), çeşitli federal kurumlarla ortaklaşa çalışarak şu ana kadar yedi Ulusal Arazi Örtüsü Veritabanı (NLCD) ürünü geliştirdi ve yayınladı: NLCD 1992, 2001, 2006, 2011, 2016, 2019 ve 2021. 2016 sürümünden itibaren, arazi örtüsü ürünleri iki ila üç yıllık aralıklarla oluşturuldu.
