Evolution of the lowest amazon basin modeled from the integration of geological and SRTM topographic data
Morphologic features obtained from Shuttle Radar Topographic Mission (SRTM) data, integrated with geologic information, are emphasized in this paper in order to provide the basis for understanding the development of the lowest Amazon drainage basin
Soil parent material delineation using MODIS and SRTM data
The aim of the study was to develop a robust, remote sensing (MODIS and SRTM) based procedure to delineate soil parent material (PM) classes for small scale soil mapping applications. This quantitative procedure aimed to maintain the original
and thermal channels were used to compile the RS dataset which was later complemented with SRTM data and terrain derivatives as well. - (AM)
A comparison of SRTM and high-resolution digital elevation models and their use in catchment geomorphology and hydrology : Australian examples
The AA. examine the Shuttle Radar Topography Mission (STRM) data for 3 catchments in Australia over a range of climates, geology and resultant geomorphology. The SRTM data are compared with high resolution digital elevation models. The AA. use basic
hydrology and geomorphology, as in all cases SRTM-derived catchment area is incorrect and smaller digital elevation grid sizes are required for accurate catchment-wide assessment.

Réduction du chatoiement et apport des données ASAR ENVISAT et MNE SRTM à la cartographie hydrostructurale du bassin côtier de l'Agnéby (Sud-Est de la Côte d'Ivoire)
images ASAR/ENVISAT et du modèle numérique d'élévation (MNE) de la campagne SRTM s'est révélé très pertinent pour la cartographie hydrostructurale du bassin de l'Agnéby. La synthèse des structures géologiques interprétées a permis de disposer d'une base
Satellite imageries from Landsat ETM+ and ERS (European Remote Sensing) Radar sensors, together with elevation data collected by the Shuttle Radar Topography Mission (SRTM) in addition to recent and older bibliography, have led to the hypothesis
Post-1930 directions to land-use changes in the Polish-Slovakian border region of the Małe Pieniny Mts. are presented, on the basis of research concerning archival topographic maps, contemporary panchromatic satellite data and an SRTM digital
remote sensing, field survey and historical sources were correlated and correction factors established; the SRTM was found to be partly unsuitable for further assessments. Further analysis of remote sensing data was used to investigate the Sudd's inland
