Antarctica without ICE

One of the earth’s most alien landmasses, the Antarctic’s rocky surface, concealed by a vertical ice crust of up to more than 3km (average thickness 1,6km), was unveiled, at least digitally, at an unprecedented detail in spring 2013. Scientists have created a significantly improved map of the continent’s bedrock in the frame of the bedmap2 project led by the British Antarctic Survey. While the previous version ‘bedmap’, produced in 2001, gave a general overview of the Antarctic’s topography, the high spatial resolution of bedmap2 shows a landscape of mountain ranges, hills and vast plateaus dissected by canyons and gorges. Thus, it conveys the cartography of the bedrock terrain much closer to reality than ever portrayed.

(LSA) Land suitability assessment for a Wind Farm location (2011)

What is a  Land Suitability Assesment?: Also known as layer-based GIS, this is the most frequent form of geographic-data space representation. Particularly, LSA (Land Suitability Assessments) is a very complex analysis in which the overlapping of thematic maps result helpful. The analysis is based on the combination of different thematic layers such as topographic, geologic or drainage as well as in their interpretation independently from one to another. Wind Farm location selection: Land suitability analysis. wind farm UK Criteria to locate a wind farm in Europe differ a little bit from one country to another. In the case of the British Isles, the British Wind Energy Association (BWEA) estimates that the extension average of a wind farm with 20 turbines is "1" square kilometer (BWEA). The principal objective was to locate a suitable area to construct a 90 MW Wind Farm. The analysis was divided into two levels: A national level to obtain p
