The purpose of the Data Preservation WG is to provide a venue and mechanism for seeking technical and institutional solutions to the challenge of preserving digital geospatial data.
Delny is a Python package which can be used to make a Delaunay triangulation from a set of n-dimensional points. It is effectively a Python interface to libqhull, the C library of the Qhull program, but (currently) restricted to Delaunay triangulation. It was first developed to use in a mesh generator developed as dissertation at the University of Southampton with Hans Fangohr as supervisor. This very specific application area was the reason for the limited functionality of the libqhull wrapper, which in turn is likely the reason that there is useable code available.
This article provides an overview of Linux-based tools for Geographic Information Systems (GIS), including a quick take on the ESRI's ArcReader. Future articles will explore this and other individual tools in greater depth.
The international quarterly e-journal on sciences and technologies affined to history of cartography and maps.
Principal aim of the journal is: To couple issues on history of cartography and maps with a variety of possibilities offered by the new digital information and communication technologies. To bring together, in harmonic convergence, historians of cartography and maps, cartography scholars and experts in new digital cartographic technologies in order to create a common space of research targeting at the broadening of cartographic and map history access and expertise.
This journal is a pluralist peer reviewed international journal which does not obey any particular ideological, theoretical or methodological approach in dealing with humanistic, artistic, scientific and technological issues related to map history and cartographic heritage in the large.
I joined the EVASION team in september 2006 in order to work on real time rendering of natural landscapes as a whole. I'm interested in the animation and realistic rendering of terrain, atmosphere, ocean, vegetation, rivers, clouds, etc. I'm looking for real-time and scalable algorithms allowing users to navigate freely anywhere in very large landscapes (up to whole planets), from ground to space, without visible transitions.
ESRI's GIS (geographic information systems) mapping software helps you understand and visualize data to make decisions based on the best information and analysis.
Der FOSSGIS e.V. ist ein eingetragener und gemeinnütziger Verein. Unser Ziel ist die Förderung und Verbreitung freier Geographischer Informationssysteme (GIS) im Sinne Freier Software und Freier Geodaten.
government-funded and approved agencies such as the Ordnance Survey and UK Hydrographic Office and Highways Agency collect data using our funds should make that data available for free
