NLS Orthophotos는 핀란드 전역을 포함하는 항공 사진 데이터 세트입니다.
이 데이터는 Mavi(농촌청)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 보통 1~3년 전 데이터입니다. NLS 정사영상은 3년마다 업데이트됩니다 (북부 라플란드의 경우 12년).
이 이미지에서 밴드는 근적외선, 빨간색, 녹색입니다.
(데이터 세트 ID에서 VV는 'vääräväri', 즉 거짓 색상을 의미함)
