How do you find your geo-data? ESRI DevMeetup, 07 June 2011 Mark Wimer Thanks to Nick Furness for roping us all into this – and supplying beer!
What’s improved in search? Search engines, of course Images/thumbnails help visually Authority, dates more likely to be used in titles Much more data, for different uses & users: contrast ArcGIS online with GLCF @UMD
