[Feed #3] Data scientists, IKEA heat map, GDEM Aster, MapQuest Elevation Service, Spatial models of Peace, GeoKettle, and other things

Harold Fisk's map of Mississippi River flooding over time, made in 1944
Here's a collection of articles I found on the net arranged by topics from the more general to the more technical.  
Articles in French are listed afterwards.


- Big Brother is watching you

- What your favorite map projection says about you


- The Economist on the explosion of Data

- Barack Obama's looking for Data scientists with preferred skill in R language

- Job trends for different keywords: "big data", "statistician", "data scientist", "R statistician", and R "data scientist". Maybe R is worth learning if you're looking for a job.

- About building a data science team


- When mapping meets art

- More traditionnal maps of volcanoes' geology, but very pretty

- IKEA heat map

- A realistic Manhattan map model
I think this creation can be connected to this project that makes people whose heritage is threatened participate around 3D model

- Okay, my blog is mostly spatial but one must admit representing data on a map is not always the best solution

- About animated geospatial data

- Unusual cartograms. I prefer these ones because geometries are not altered. I think I'll write an article on achieving a similar result in R.

- An interesting statistical representation. I think I'll give it a try with R using spdep package. I'll publish the solution in a future post

- Metadata is almost always literal. Could we use a new term MetaMap, which would be metadata of a map synthetized as a map (Ouch, I have an headache...)

- Crime rates as topographic maps: why not?

- Jack Kerouac Litteracy as wonderful information graphics

- A website to understand maths by Apple designer Bret Victor. After all, designing information or whatever is all about making things simpler and accessible, isn't it?


- Tutorials and guidelines on how to participate to Open Street Map with this website

- Open Public Transportation Maps:

- R and OpenStreetMap

- I'll soon publish a post comparing the newly available Digital Elevation Model GDEM ASTER and the Digital Terrain Model from the French National Geographic Institute using R


- Several techniques on making maps using free tools

- Making maps with R

- Another one on the same subject


- A webservice search engine, for example with keyword "geographic"

- Using MapQuest Elevation Service inside a  script:

- Always about MapQuest: no preset limit on Free Map API Transactions:

- Always about web API services, here is a tutorial on how to map research hot spots using Google Maps API with R


- Using LIDAR in archaeology.

- A nice resource if you wish to dig into spatial stats

- Spatial stats and models could help predict social violence and harmony. A study made for Switzerland.


- workshops on developing OGC compliant web apps

- GRASS in the cloud

- Some PostGIS 2.0 cheat sheets. The main new functionalities of PostGIS are native raster support and topology functions.

- On my blog, you'll find some resources about the spatial ETL Talend - Spatial Data Integrator. Here are some keynotes of another tool: Pentaho Based ETL GeoKettle from Spatialytics


- Très bon article sur les bonnes pratiques et astuces pour l'administration et l'exploitation d'une base de données PostgreSQL / PostGis

- Je cherchais depuis longtemps un article  efficace, progressif et pédagogique sur les expressions régulières. Je l'ai trouvé. 

- Toujours un article de Martin Laloux, la procédure pour télécharger les dalles du modèle numérique d'élévation GDEM ASTER

- Un document technique du Centre d'études sur les Réseaux, les Transports, l'Urbanisme et les constructions publiques sur la constitution et l'exploitation de données agrégées à la maille
"Raster or Vector, that is the question" 

- Un guide de 260 pages sur les solutions opensource (300 solutions référencées) édité par la société Smile. N'hésitez pas à jeter un coup d'oeil à leurs livres blancs, notamment celui sur l'ergonomie de sites internets et le décisionnel opensource

- Un article intéressant sur l'infonuagique (Cloud Computing en anglais)

- Saviez-vous que des Web Processing Services sur la BDCartage étaient disponibles? Plus d'infos ici:

- J'avais rédigé auparavant un document concernant une méthode d'analyse de l'évolution de la tâche urbaine.
Si ce sujet vous intéresse, ce document sur le modèle SpaCelle vous intéressera sans doute.
