As ortofotos da NLS são um conjunto de dados de fotos aéreas que cobrem toda a Finlândia.
Esses dados são fornecidos pela SMK(Agência de Energia, anteriormente abreviada como SMK). Uma ortofoto é uma combinação de várias fotos aéreas individuais. O conjunto de dados de fotos aéreas em formato ortofoto está disponível como o conjunto de dados mais recente, que consiste nas fotos aéreas mais recentes disponíveis. Os dados mais recentes geralmente têm de um a três anos. As ortofotos do NLS são atualizadas a cada 3 anos (na Lapônia do Norte, a cada 12 anos).
Nessas imagens, as bandas são infravermelho próximo, vermelho e verde.
No ID do conjunto de dados, VV significa "vääräväri", cor falsa.
Mencione o nome do licenciante (o Serviço Nacional de Levantamento de Terras da Finlândia), o nome dos conjuntos de dados e o momento em que o Serviço Nacional de Levantamento de Terras entregou os conjuntos de dados (por exemplo: contém dados do Serviço Nacional de Levantamento de Terras do Banco de Dados Topográficos da Finlândia 06/2014).
