• Very Spatial has assembled a very long linklist to GIS software.
• YubaNet.com has a well-written article on crater chains that follows up on the discovery of craters using Google Earth a month or two ago.
• NASA World Wind is up to 1.3.5, geo extensions for SPARQL, a query language for RDF. He’s also written up an XSLT stylesheet that converts these results into KML.

  This would be an excellent tool for newsreaders to adapt to generating proximity alerts from GeoRSS feeds.

• Kathryn Cramer writes that RISE-PAK, the rapid-response effort after the Pakistan Quake to which Global Connections contributed satellite data via Google Earth, has won the Stockholm Challenge 2006 award.
• Converjed notes another entry in the race for the enhanced displays we’ll be using a few years from now: Iowa State’s C6.
