Global geological map of Venus
The surface area of Venus ( 460 10 km) is 90% of that of the Earth. Using Magellan radar image and altimetry data, supplemented by Venera-15/16 radar images, we compiled a global geologic map of Venus at a scale of 1:10 M. We outline the history of geological mapping of the Earth and planets to illustrate the importance of utilizing the dual stratigraphic classification approach to geological m...
متن کاملOntology-aided annotation, visualization, and generalization of geological time-scale information from online geological map services
Geological maps are increasingly published and shared online, whereas tools and services supporting information retrieval and knowledge discovery are underdeveloped. In this study, we developed an ontology of geological time scale by using a RDF (Resource Description Framework) model to represent the ordinal hierarchical structure of the geological time scale and to encode collected annotations...
متن کاملRemote sensing applications to geological problems in Egypt : case study , slope instability
The Sharm El-Sheikh/Ras-Nasrani area is one of the most attractive tourist resorts in Egypt particularly and in the world in general. The area has been rapidly growing during the last few years. Many construction projects including villages, hotels, beaches, and roads have recently been undertaken. The following study demonstrates the use of high-resolution satellite images, QuickBird imagery, ...
متن کاملThe Meatiq dome (Eastern Desert, Egypt) a Precambrian metamorphic core complex: petrological and geological evidence
The Meatiq basement, which is exposed beneath late Proterozoic nappes of supracrustal rocks in the Central Eastern Desert of Egypt, was affected by three metamorphic events. The ophiolite cover nappes show only the last metamorphic overprint. The M1 metamorphic event (T≥750 °C) is restricted to migmatized amphibolite xenoliths within the Um Ba∞anib orthogneiss in the structurally lowest parts o...
متن کاملMap Description and Management by Spatial Metadata: Requirements for Digital Map Legend for Planetary Geological and Geomorphological Mapping
Instruments carried along on missions to, e.g., Mars, the Moon, Venus, and various Outer-Solar System objects, produce a rich variety of image data recorded in different wavelengths and some of them allow to derive additional datasets (e.g., digital terrain models). These data form the basis for geologically exploring the evolution of planetary bodies by analyzing and geoscientifically interpre...
