이러한 Landsat 4 TM 컴포지트는 스케일링되고 보정된 센서 상단 복사휘도를 나타내는 DN 값을 사용하여 L1T 직교 보정 장면에서 만들어집니다. 2017년 5월 1일 이후 USGS에서 더 이상 Pre-Collection Landsat을 생산하지 않으므로 이 컬렉션은 완료되었습니다. 컬렉션 1 기반 데이터 세트로 전환하세요. 이 문서를 참고하세요.

It includes 7 spectral bands, and a quality assessment band (BQA), with a 30-meter resolution. Data was created from all the scenes in each annual period using the most recent pixel as the composite value. The USGS discontinued this Pre-Collection, and recommends switching to a Collection 1 dataset. The dataset is in the public domain and the source must be cited as the USGS.\n"]]
