Mercury’s Debussy Quadrangle (H14) lies between 0–90° E and 22.5–65° S. Here we use MESSENGER data to produce the first geological map of this quadrangle at a scale 1:3,000,000, based on linework completed 1:300,000. We distinguish crater units plains units. For compatibility with historic recent maps other Mercury quadrangles, global (Main Map), have made two versions map, craters classified a...

this work aims to extract the mineralogical constituents of the lahroud hyperion scene situated in the nw of iran. like the other push-broom sensors, hyperion images suffer from spectral distortions, namely the smile effect. the corresponding spectral curvature is defined as an across-track wavelength shift from the nominal central wavelength, and alters the pixel spectra. the common “column me...

Mud volcanoes can be large and long lived geological structures that morphologically resemble magmatic volcanoes. Because of their capricious behaviour and their spectacular morphology and landscapes, mud volcanoes have attracted attention since antiquity. More recently, mud volcanoes have become the focus of extensive studies for natural science research, including geologists and biologists. M...

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...

Liguria is a small region in Northwestern Italy which characterized by significant and valuable geoheritage. The 1:250,000 map presented this paper displays the 120 geosites of Liguria, officially approved regional national authorities, framed context geological landscapes region. were obtained categorizing thematizing geological, lithological geomorphological data macro-units with similar char...

The regional engineering geological conditions and geological hazard evaluation is the important part of realizing the railway geological selection, However, the accuracy of the evaluation largely depends on the reliability of basic information and reasonable mathematical model. Remote sensing provides reliable geological information and accurately reflects the geological conditions along the r...

considering the seepage and choosing an efficient sealing method is very important in dam projects. this issue has a close relationship with engineering geological properties of the dam site. chapar-abad dam is an inhomogeneous earth-fill dam of 44.5 meters height, crest length about 427 meters and a reservoir capacity of 127 million cubic meters. the dam project is under construction and is lo...

A wide range of methodologies and software applications have been developed to generate 3-Dimensional (3D) geological model data. One of the main open issues is the exchange of these heterogeneous data from different sources, which influences the sharing and integration of 3D geodata. It is also a necessity to take into consideration the semantics of 3D geological data to enable its full exchan...
