TLS for Use in Geology

Digital Outcrop Modelling in Brazil
Terrestrial Laser Scanning (TLS) enables 3D coordinates to be obtained of points which can be georeferenced with respect to a national geodetic system using GNSS (Global Navigation Satellite System). Textures and colours of objects captured are obtained by the digital camera mounted on or integrated in the scanner. In Brazil, TLS is applied on a regular basis in engineering, cartography and architecture but its application in Digital Outcrop Modelling (DOM) still requires further scrutiny. The author captured and processed an outcrop in Brazil using TLS and GNSS. The digital modelling of outcrops using TLS and the interpretation and visualisation of... (read more)

Aussie Geology at your Fingertips

Mining industry explorers, earthquake and climate-change scientists, and members of the public can now access a 'stack' of information about Australia's geology at the click of a button. Developed by CSIRO and AuScope in collaboration with other research organisations around the country, a new open-access network of geospatial data, and its supporting infrastructure, the Spatial Information Services Stack (SISS), will enable users to explore Australia's geology on a national scale.     AuScope CEO, Dr Bob Haydon, said  that using this network of data anyone can investigate the geological history of the continent and researchers can use it to gain...

Review of the 2nd Virtual Geology Conference

Where Geomatics Meets Geosciences
At the 2nd Virtual Geology Conference (VGC 2016) from 22-23 September 2016, geomatics met the geosciences in the beautiful fjord town of Bergen in western Norway. This follow-up to the VGC 2014 in Lausanne, Switzerland, which at that time was named the ‘Vertical’ Geology Conference, established the beginnings of a biannual VGC conference series. The conference is intended as a multidisciplinary forum for researchers in geosciences, geomatics and related disciplines to share their latest developments and applications in the growing field of close-range data collection techniques. (By Tobias Kurz, VOG Group, Uni Research AS, Norway) VGC 2016 was hosted by... (read more)

OneGeology

Standards developed by the members of OGC play a key role in OneGeology, a global project to produce the first digital geological map of the world. OneGeology is supported by UNESCO and six other international umbrella bodies. It is the flagship project for the UN International Year of Planet Earth 2008. OneGeology is made possible by standards. For example, GeoSciML, a Web-based geoscience encoding standard developed by the International Union of Geological Sciences (IUGS), Interoperability Working Group. GeoSciML is an "application schema" of GMLthe OGC's OpenGIS Geography Markup Language Encoding for representation of geospatial features and geometry. GeoSciML also uses... (read more)

Sentinel Satellites Help to Map Minerals

The traditional way of mapping Earth’s geology and mineral resources is a costly and time-consuming undertaking. While satellites cannot entirely replace the expert in the field, they can certainly help – as a recent effort in Africa shows. Geological maps identify different types of rock, faults, groundwater and deposits. They are not only essential for building infrastructure and assessing risk, but also important for locating and mining natural resources. The European Space Agency (ESA) has recently supported a pan-African initiative to collect, interpret and disseminate satellite information on geology and mineral resources such as metallic ores. This ESA-funded effort has... (read more)
