A few words about GIS-Lab from their website:
GIS-Lab - informal non-commercial community of GIS/RS specialists, we grow ourselves and help grow others.
GIS-Lab exists since April 2002 as an independent online resource specializing in geographic information systems (GIS) and remote sensing (RS). At present, the site is primarily oriented towards Russian-speaking GIS community, however, we do our best to translate as many materials as possible into English.
The GIS-Lab is the very first blog in Russian language syndicated with the Planet OSGeo, what makes the planet yet more international geo-caffee.
