Geology is about describing the various types of sediment that makes up our earth. The information is gathered using coring and drilling techniques from geotechnical surveying and often combined with geophysical surveying and seismic techniques to obtain a complete image of not only the type of material but also its distribution.
Geological surveys perform an important role in construction and engineering and land and water management but also in farming and conservation and mining & energy to determine the correct type of bottom.
A series of strong earthquakes recently hit populated areas in the south of the Caribbean island of Puerto Rico, causing major damage to properties and infrastructure. Geoxphere and WaldoAir were mobi...
In 1998 the Government of India Department of Science & Technology (DST) launched a National GPS Programme for Earthquake Hazard Assessment. The recent major earthquakes in the South East Asian region...
Diverse environmental effects, climatic changes and human alterations of the ecosystems are deeply changing Earth’s surface processes and creating environmental challenges that researchers are strug...
Space technology has been widely used for disaster management in China. As the decision-making support agency for Chinese disaster management, the National Disaster Reduction Center of China (NDRCC) h...
In Western Canada, substantial lengths of the transportation corridors are located within steep mountainous terrain and deeply incised river valleys. This is also the case for the Canadian National (C...
Satellite radar interferometry (InSAR) is a technique that can measure millimetre-scale movement of the ground from space. It does this by comparing the return echoes, and thus the signal-path length,...
Excessive groundwater extraction is probably the main factor causing land subsidence in urban areas of Indonesia. Decreases in groundwater level may reach 15 metres a year. Monitoring of land subsiden...
Advances in the use of GIS and 3D modelling software have meant that there is now a greater opportunity to develop geo-environmental information systems for urban development, argues Dr Katherine Roys...
Surveyors, mappers, geodesists and other scientists, as well as climbers and mountaineers from around the world, have long held a curiosity to know the official elevation of Denali, the continent's h...
When people think about landslides, they usually imagine large mud streams which cause considerable loss of life. Whereas such large-scale disasters are rare, smaller landslides are a much more freque...
Geospatial mapping specialists and technology from GeoSLAM have been involved in a project to map the Lombrives cave in southern France. The Human Adaption Institute conducted a pioneering isolation e...
Excessive groundwater extraction in the Bandung Basin has led to rapid sinking of the water table and is hypothesised as the main cause of land subsidence. Periodical GPS surveys were conducted from F...
A two-week field trip to Iceland – that was all they were told beforehand. After one year of studying at Delft University of Technology, MSc students headed towards this geodetically very interestin...
Geodesists and surveyors in Iceland face considerable challenges due to the deformation effects of earthquakes, volcanic eruptions and glaciers on the geodetic networks. This article provides insight ...
In the geospatial technology sector there is a transitive relationship between the big players such as Leica Geosystems, Trimble and Topcon, who can persistently pursue innovation, and small to medium...
