2011'den beri Arazi Yönetimi Bürosu (BLM), Değerlendirme Envanteri ve İzleme (AIM) stratejisi aracılığıyla arazi sağlığını bilgilendirmek için saha bilgileri toplamaktadır. Bugüne kadar BLM arazilerinde 6.000'den fazla karasal AIM alan çalışması toplandı. BLM AIM veri arşivi …
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.
