A Script-Driven Approach to Mapping Satellite-Derived Topography and Gravity Data Over the Zagros Fold-and-Thrust Belt, Iran

Abstract Integrated geophysical mapping benefits from visualizing multi-source datasets including gravity and satellite altimetry data using 2D 3D techniques. Applying scripting cartographic approach by R language GMT supported traditional in QGIS is presented this paper with a case study of Iranian geomorphology special focus on Zagros Fold-and-Thrust Belt, unique landform the country affected complex geodynamic structure. Several modules ’tmap’ ’raster’ packages were shown to illustrate efficiency console-based scripts. Data sources included high-resolution raster grids GEBCO/SRTM, EGM-2008, SRTM DEM vector geologic layers USGS. The objective was visualize thematic maps Iran: topography, geology, satellite-derived anomalies, geoid undulations geomorphology. Various techniques applied plot topographic field gradients categorical variations geological structures relief along Belt. Elburz, Zagros, Kopet Dag Makran slopes, Dasht-e Kavir, Lut Great Salt Desert visualized 3D-and geomorphometric properties (slope, aspect, hillshade, elevations) modelled R. series 11 new made combination GIS for comparative geological-geophysical analysis.
