Os dados digitais de elevação da Shuttle Radar Topography Mission (SRTM, consulte Farr et al., 2007) são um esforço de pesquisa internacional que obteve modelos digitais de elevação em uma escala quase global. Esse produto SRTM V3 (SRTM Plus) é fornecido pelo NASA JPL com uma resolução de 1 segundo de arco (aproximadamente 30 m).
Esse conjunto de dados passou por um processo de preenchimento de vazios usando dados de código aberto (ASTER GDEM2, GMTED2010 e NED), ao contrário de outras versões que contêm vazios ou foram preenchidas com fontes comerciais.
Para mais informações sobre as diferentes versões, consulte o
Guia rápido do SRTM.
Salvo indicação em contrário, as imagens e os vídeos nos sites públicos do JPL (sites públicos que terminam com um endereço jpl.nasa.gov) podem ser usados para qualquer finalidade sem permissão prévia. Para mais informações e exceções, acesse o site da política de uso de imagens do JPL (em inglês).
