이 데이터 세트는 그린란드 빙하에 대해 15m 거리의 완전한 육지 및 해양 분류 마스크를 제공합니다. 빙하의 표지는 USGS에서 배포한 Landsat 7 Enhanced Thematic Mapper Plus (ETM+)의 보정된 범크로매틱 (밴드 8) 이미지 조합을 사용하여 매핑되었습니다.
NASA Making Earth System Data records for Use in Research Environments (MEaSUREs) 프로그램의 일부인 이 데이터 세트는 선택된 빙하 출구 지역의 월평균 속도 지도로 구성되어 있습니다. 지도는 Landsat이 얻은 광학 이미지 쌍 사이의 시각적 특징을 추적하여...
