<p>Geological mapping and cartography on Earth encompasses principally the description of the landforms, i.e. geomorphology, the lithology and the age (stratigraphy) of the rocks found at or beneath the Earth’s surface. By interpretation of this information genetic information (process, event and environment) can be derived from the rock units encountered and often is included in geological maps, in particular in larger scale maps.</p><p>Mapping agencies and geological survey organisations everywhere have for centuries been developing their own regional or national mapping methods and representation colour sets and symbols to represent the geological information on paper and now in spatial databases and GIS.</p><p>BGR and its predecessors has been undertaking geological mapping at both large and small scales since the 19<sup>th</sup> century and through this has gained considerable mapping experience. This contribution describes the establishment of mapping rules and guidelines for three small-scale European cross-boundary mapping projects implemented through international cooperation: the IGME 5000 (pre-Quaternary) and the IQUAME (Quaternary) projects, and the EMODnet Geology seafloor work-package. The experience gained within the projects in the creation and use of standardised specifications for data models and cartographic aspects such as symbols and colours will be introduced and challenges, advantages and disadvantages  will be discussed.</p><p>All three projects include off-shore geological information; in particular these aspects of the marine mapping and cartography may be partly comparable to planetary mapping, since “even with all the technology that we have today -- satellites, buoys, underwater vehicles and ship tracks -- we have better maps of the surface of Mars and the Moon than we do the bottom of the ocean.” [Gene Feldmann, NASA, 10.08.2009].</p><p>Thus the experience and results in Earth mapping described may contribute and serve as “good practise” for the benefit of the fascinating new field of planetary mapping.</p><p> </p>

Energy Potential

In Australia the future demand for energy is predicted to increase rapidly. Conventional energy resources soaring prices and environmental impact have increased the interest in renewable energy technology. As a result of that the Australian government is promoting renewable energy; such as wind, geothermal, solar and hydropower. These types of energy are believed to be cost-effective and environmentally friendly. Renewable energy availability is controlled by climatic conditions such as solar radiation, wind speed and temperature. This paper aims to assess the potential of renewable energy resources, in particular wind and solar energy in an Australian subtropical region (Central and North Queensland) namely, Gladstone, Emerald, Rockhampton, Yeppoon, Townsville, and Cairns. Analysis is done by using the latest statistical state of Queensland energy information, along with measured data history of wind speed, solar irradiations, air temperature, relative humidity, and atmospheric pressure for those sites. This study has also shown that national assessments of solar and wind energy potential can be improved by improving local climatic data assessments using spatial databases of Central and North Queensland areas.
