geo.admin.ch: bringing Swiss geodata potential to life

A priorized project of eGovernment Switzerland Usage and exchange of geodata is fostered by geo.admin.ch in a significant way. The Federal geoportal is operated by the Federal Office of Topography, swisstopo, on behalf of the coordinating body for Federal geographical information with the aim to implement the Geoinformation Act. The purpose of this Act is to ensure that geodata relating to the territory of the Swiss Confederation is made available to the Federal, Cantonal and municipal authorities, to industry and commerce, to academic and scientific institutions and to society at large, for the broadest possible use, in a sustainable, up-to-date,…

short announcement: TopoToolbox 2: Geomorphometry made easy in MATLAB

< p align=”justify”>Digital elevation models (DEMs) exist today for the entire globe with consistent quality. Improvements in sensors and data processing give a clue that in the future elevation data will be available in even better spatial resolution and accuracy. Discovering the richness of information inherent in DEMs should thus be supported by good software. Here, I want to give a brief account of TopoToolbox 2, the second version of a MATLAB toolbox for exploring and analyzing DEMs. Dirk Scherler from Caltech and I have been working on many changes to the previous version to make TopoToolbox faster, more memory…
