A major geological GIS project: the 1:5 Million International Geological Map of Europe and Adjacent Areas (IGME 5000) is being managed and implemented by the Federal Institute for Geosciences and Natural Resources (BGR). The aims of the project are to develop for the whole of Europe a GIS underpinned by a geological database, a printed map depicting up-to-date and consistent geological informat...

The purpose of this study is to assess the vulnerability urban blocks earthquakes for Tehran as a city built on geological faults using an artificial neural network—multi-layer perceptron (ANN-MLP). Therefore, we first classified earthquake evaluation criteria into three categories: exposure, sensitivity, and adaptability capacity attributed total 16 spatial criteria, which were inputted networ...

The Alborz mountain range in northern Iran is part of the active and seismic Alpide belt, where assessing hazards crucial due to region’s history large instrumental earthquakes destructive background. Moment rate estimation, which quantifies tectonic activity, offers a novel approach understanding energy potential regions. In this study, regional perspective employed investigate maximum horizon...

logic map of Northeast Gale crater. Solid and patterned shapes represent unique geologic units identified through morphological classifications using HiRISE and CTX. Blue and green outlines indicate identification of mafic and hydrated mineral phases found through the use of CRISM. STRATIGRAPHY OF THE GALE CRATER RIM AND FLOOR UNITS. J. Buz 1 and B. L. Ehlmann 1,2 , 1 Geological & Planetary Sci...

particulate and gaseous emissions of pollutants from industries and auto-exhausts are responsible for rising discomfort, aggravates respiratory and cardiovascular. in this study, a system for air quality information in tehran city has been developed, using an online web-based geographic information system. this web-based gis application allows users to recognize areas with a potential increase ...

Regional scale geological maps are still not available for many remote parts of the Earth. All geological maps contain two fundamental pieces of information: a) lithological data: a list of the various rock types present, and b) structural data: geometrical information that describes the spatial relationships of the various rock units. For the purposes of regional scale geological mapping the s...
