Last week, I blogged about Open Street Map over on my company’s blog, The Viewshed about Open Street Map and touched briefly on the subject of data quality. I cited the study by Muki Haklay that compares (favorably) the quality of data found in OSM with Ordnance Survey data. More on the subject of OSM [...]

Map rendering using stylesheets: Cartagen
July 13th, 2009 · No Comments · Geographic
Recently released by members of the MIT Media Lab in Cambridge, MA comes this code that uses Geographic Style Sheets (GSS) to drive the map rendering process for web maps in native HTML 5. What this means, according to the developers, is that individuals can style their own maps enabling them to create and communicate [...]

Ushahidi :: Crowdsourcing Crisis Information (FOSS)
December 4th, 2008 · No Comments · Mobile, OpenSource, mapping
I accidentally bumped into this site whose purpose is “crowd-sourcing crisis information”. (Sorry; bad metaphor.) Initial deployments still in alpha, but should be interesting to follow in the coming months, especially in light of the value demonstrated by the Twitter platform during the recent siege in Mumbai.

Here’s another sign (as if we needed one) that geospatial information is rapidly merging with mainstream IT. Linux.com published a nice article on getting started with Geoserver.

Crowd-sourced seismological data? Quake-Catcher Network Home Page
April 24th, 2008 · 1 Comment · Geographic, OpenSource
I tend to think that one of the more important distinguishing features of Web2.0 applications is the collaborative nature of the technology, which has opened up previously arcane vocational amd professional specialties to amateurs. This is what Clay Shirky refers to as “mass amateurization”. The really interesting thing about mass amateurization is that it has [...]

GRASS 6.3.0RC6 now available
March 22nd, 2008 · No Comments · Geographic, OpenSource
The source code for the latest release candidate of GRASS is now available at the OSGEO site. I’ve always thought the analytical capabilities of GRASS were quite robust, but could never quite get used to the old interface written in TCL/TK and so I never had the patience to ascend the learning curve. This new [...]

I’m just coming round to nice general interest interview with Tyler Mitchell in Linux Journal. Tyler is the Executive Director (and chief evangelist) of the Open Geospatial Foundation (OSGeo). For those of you who have been attending FOSS4G for the last few years, you won’t find much (besides a concise summary) that you weren’t already [...]
