Modelos Digitais de Elevação tem sido utilizados para diversas aplicações, mas a experiência tem demonstrado que o uso efetivo destes modelos deve ser melhorado com a consideração de aspectos como o uso de metadados, a verificação da confiabilidade da informação resultante e a influência das diferentes escalas. Portanto, o objetivo da **Análise de Elevação** é incluir o estudo destes aspectos, desenvolvendo pesquisas e algoritmos, de modo a ser um campo de estudo mais completo que a Modelagem Digital de Elevação. \\ | Modelos Digitais de Elevação tem sido utilizados para diversas aplicações, mas a experiência tem demonstrado que o uso efetivo destes modelos deve ser melhorado com a consideração de aspectos como o uso de metadados, a verificação da confiabilidade da informação resultante e a influência das diferentes escalas.

Topographic data acquired during the Shuttle Radar Topography Mission (SRTM), in February 2000, flew onboard Space Shuttle Endeavour. The SRTM radar contained two types of antenna panels, C-band and X-band. C-band data processed at the Jet Propulsion Laboratory and X-band processed and distributed by DLR.
