I prompted a flurry of PostGIS hate (and some love) on Twitter last week, documented via Storify. I’ve been using PostGIS for around 2 years now both at Stamen and before that at The Washington Post. Let me say upfront that PostGIS is amazing and is definitely in the top 5 best FOSS4G (free and open source software for geo) out there. It is a super powerful spatial data store that is free to download, install, and use (even in commercial projects!). It’s can also be mind numbingly difficult to install and use. It doesn’t matter how awesome something is unless it’s usable. Kelso’s Corner
Le site Histoire-Géographie de l'académie de Rouen Même s’il est parfois nécessaire de réaliser soi-même la jointure avec les données statistiques, les couches vectorielles disponibles sur internet et téléchargeables gratuitement sont relativement nombreuses.

Nous en présentons ici une sélection utile pour l’enseignement de nos disciplines, aussi bien en Géographie qu’en Histoire.

Data - GIS at University of Chicago Some of these data sites are more specific by subject or by region than others. However, it is suggested to first try the links under the “National and International Data” heading before going to more specific sites. The National and International sites are more generic in some instances and may have the data that you are trying to locate. When searching these sites, the keywords of “GIS” and the “subject” in question are usually good starting points if you are having difficulty.

With hurrican Irene on its way. I thought some of you may be interested in these historical hurricane shapefiles. These cover the period from 1851 up to 2004. I'm working also to include more recent hurricanes in the near future. The paths of tropical cyclones and major hurricanes from 1851 to 2004. The term "tropical cyclone" is a generic term for a low-pressure storm system that usually forms in the tropics. Download free Hurricane GIS Shapefile Map Layers
