APLICAÇÕES DOS MODELOS DE ELEVAÇÃO SRTM EM GEOMORFOLOGIA / SRTM DEMs APPLICATIONS IN GEOMORPHOLOGY

Revista Geográfica Acadêmica, 2008
The Shuttle Radar Topography Mission (SRTM) was realized to map the morphology of the Earth’scontinental areas between 60ºN and 54ºS, using radar interferometry. Application of Digital ElevationModels (DEMs) in geomorphology allow calculation of topography-related variables with speed andprecision.

Ensuring globally the TanDEM-X height accuracy: Analysis of the reference data sets ICESat, SRTM and KGPS-tracks [PDF]

, 2009
The TanDEM-X mission will derive a global digital elevation model (DEM) with satellite SAR interferometry. Height references play an important role to ensure the required height accuracy of 10m absolute and 2m relative for 90% of the data.

Synthesis and characterization of a disubstituted piperazine derivative with T-type channel blocking action and analgesic properties

Molecular Pain, 2016
Background T-type calcium channels are important contributors to signaling in the primary afferent pain pathway and are thus important targets for the development of analgesics. It has been previously reported that certain piperazine-based compounds such

Traffic monitoring using SRTM along-track interferometry [PDF]

IGARSS 2003. 2003 IEEE International Geoscience and Remote Sensing Symposium. Proceedings (IEEE Cat. No.03CH37477), 2004
In February 2000, the shuttle radar topography mission SRTM was flown as the first single-pass SAR interferometer in space. The goal was to obtain a global digital elevation model. Therefore, a secondary receive-only antenna on the top of a 60 m long deployable mast supplemented the primary transmit and receive antenna mounted in the shuttle cargo bay.
