ArcticDEM은 광학 스테레오 이미지, 고성능 컴퓨팅, 오픈소스 사진 측량 소프트웨어를 사용하여 북극의 고해상도, 고품질 디지털 표면 모델 (DSM)을 자동으로 생성하는 NGA (National Geospatial-Intelligence Agency) 및 NSF (National Science Foundation) 공공 민간 이니셔티브입니다. 여기에는 초목, 트리 캐노피, 건물 등이 포함됩니다.

REMA (Reference Elevation Model of Antarctica)는 남극 대륙의 고해상도 타임 스탬프 디지털 표면 모델 (DSM)으로 2미터 및 8미터 공간 해상도를 사용합니다. 모자이크 처리된 DEM 파일은 공동 등록, 블렌딩 및 패더링된 여러 스트립으로부터 컴파일되어 에지 매칭 아티팩트를 줄입니다.
