NLS Orthophotos는 핀란드 전역을 포함하는 항공 사진 데이터 세트입니다.
이 데이터는 SMK(에너지청, 이전 약어 SMK)에서 제공합니다. 오르토포토는 여러 개별 항공 사진의 조합입니다. 직교 사진 형식의 항공 사진 데이터 세트는 사용 가능한 최신 항공 사진으로 구성된 최신 데이터 세트로 제공됩니다. 가장 최근 데이터는 일반적으로 1~3년 전 데이터입니다. NLS 정사영상은 3년마다 업데이트됩니다 (북부 라플란드에서는 12년).
(데이터 세트 ID에서 V는 'väri'의 약자로, 'false color'와 달리 'color'를 의미합니다.)
