A variety of regional geoscience datasets from Nova Scotia have been co-registered and analyzed using a geographic information system (GIS). The datasets include bedrock and surficial geological maps, airborne geophysical survey data, geochemistry of lake-sediment samples, and mineral occurrence data. A number of line features, including structural lineaments, fold axes and formation contacts, ...

Recent research has suggested that changes in temperature and precipitation events due to climate change have had a significant impact on the availability and timing of streamflow. In this study, monthly temperature and precipitation data collected over 29 climate divisions covering the entire Colorado River basin and monthly natural flow data from 29 U.S. Geological Survey (USGS) gauge locatio...

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...

The remotely sensed data provides synoptic viewing and repetitive coverage for thematic mapping of natural resources. In the present study hydrogeomorphological mapping has been carried out in Ottanchattiram Block, Dindugal District, Tamil Nadu for delineating groundwater potential zones. Landsat ETM+ Geocoded FCC data in conjunction with Survey of India toposheet (1:50000 scale) were used for ...

Most 3D geological modelling tools were designed for the needs of the oil industry and are not suited to the variety of situations encountered in other application domains. Moreover, the usual modelling tools are not able to quantify the uncertainty of the geometric models generated. The potential-field method was designed to build 3D geological models from data available in geology and mineral...

After a careful examination and an extensive investigation of the Geopark development, all data of geological heritage, relevant research, tourism information and science education are integrated by the technologies of ArcGIS, MapServer and database software, based on the detailed analysis and design of system architecture, database design, map file handling, user interface design and system de...

An object-oriented and map-based prototype expert system has been developed for integrating geophysical, geological data for base metal exploration. The object-oriented knowledge representation structure and uncertainty propagation mechanisms used work well for this integrated resource exploration problem. Evidential belief function theory is utilized to manage the uncertainties in the system. ...

GeoSciML has been developed to enable the interchange of geoscience information, principally that portrayed on geological maps as well as boreholes. A GeoSciML testbed was developed both to test the implementation of the data model and its application in web services. The OneGeology-Europe project aims to use the GeoSciML data model, and build on the experience of the GeoSciML testbed, in imple...
