Last year saw the emergence of the first Massive Open Online Courses (MOOCs) focused on geospatial topics. Developed at Penn State, Maps and the Geospatial Revolution enrolled over 48,000 students from 150+ countries. In addition to offering a new (free) way to access skills and...
historical challenges and how the relationship between data quality and data governance can overcome them page 1
well said! see also the ISO standards for data quality as well as the one concerning geospatial data ISO19157
Nonetheless I liked the distinction between what we can called also intrinsec quality (described here as derived from the data provider) and the extrinsec quality depnding on the usage of this data. This is called usability in the ISO19157 which can be also described by the provider but not only!
OWNI a dessiné un quinquennat d'explosion des dépenses de l’Élysée, à partir du dernier livre de René Dosière L'argent de l’État : augmentation faramineuse des dépenses de communication et de déplacements, salaires qui ne connaissent pas la crise,...
Second one in the Guardian is by a PhD student Sarah Byrne titled Interdisciplinary research: why it's seen as a risky route. It discusses, fairly accurately, that while funding agencies and academic leaders give lip service to ...
Swarm Behavior - A single ant or bee isn't smart, but their colonies are. The study of swarm intelligence is providing insights that can help humans manage complex systems, from truck routing to military robots.
First beautiful picture ... and if we re-scoop this it may become buzz ... then we will have acted like a swarm does! but I guess what is really interesting is when something goes buzz and modify itself at the same time and then another buzz mixes with it creating a quite new ... that's quite complex as one cna only identify the origin at the beginning of the mix of things / ideas etc.!
This is the BPMN representation of the SIEL model (Loireau et al. (2006)) some interesting error propagation studies betwen categories (e.g. soil), quantitative attribute (e.g. biomass), positions (e.g. vegetaion map) etc ...are currently investigated. These would make such scientific geoworklfow models very useful for decision making.
Can meta-propagation with multivariate uptake using copula distribution be more than a theoretical solution?
I think that would do a very interesting PhD. email me if you are interested!
Concernig geosTapial datA anaLysIS and siMulAtioN (TASLISMAN project) the k-spatial entropy is quite an interesting measure to describe spatial patterns and their evolutions. Testing the significance may involves MonteCarlo re-sampling for the NULL hypothesis, but plotting multiple variable evolutions with their envelopes may necessitate a magnifier to be able to see something ... here is a very simple solution which could be applied to any similar issues!
No matter what happens, there will always be a demand for data visualisation tools. Data on its own can be pretty boring and brightening it up with images and other visual tools, it can make normally inaccessible information much easier to digest...

Geography graduate student Derek Watkins has some fun with population densities in an interactive version of William Bunge's The Continents and Islands of Mankind. The above shows areas in the world where there are at least 15 people per square mile. In the interactive, a slider lets you shift that number up to 500 where only a few spots in the world remain.
