GeoConnexion UK (Sept/Oct 2006) has an article on Scotland’s geospatial portal – The Geospatial Project Registry Home Page. While it has been around since 2005, it seems to have had some updates recently (the site says that version 2.0.1 went live in August).
The site offers a great way to find out about projects that are happening in Scotland by searching by keyword, title, area covered, and time among others. My only real critique of the site from my brief interaction was that you get a series of records, presenting detailed projects one at a time. I would have preferred to get a list of projects and then I can choose which projects to click through to see the details.
Either way if you are working in Scotland and you want to see what else is going on in the area be sure to check out the site The Geospatial Project Registry Home Page also available and gisprojects.net.
