An incredible impressive project (see the methods section), its outcome released in public domain.
I recently bookmarked GPStagr. Here are two geotag-related extensions for Firefox:
Photomap displays user contributed photos on a map.
GMiF is an third party add-on of Flickr. It will embed a Google Maps in Flickr photo page and display where the photo was taken on the maps, if the photo is geotagged.
ESRI will soon be coming out with a new version of ArcGIS (9.2). There will be free training sessions in many U.S. cities in the next two months. For information see: http://www.esri.com/events/introducing-arcgis92/index.html.
For those of you who cannot attend these sessions, there is a free virtual campus course you can take from ESRI. No registration code is needed. See http://training.esri.com. Select the Course Catalog tab, then do a search for â€œArcGIS 9.2â€³. You will see the self-study course â€œWhatâ€™s New in ArcGIS Desktop at 9.2â€³. Follow the link for this course, then click â€œTRY IT NOWâ€ under Course Purchase. You will need to log into your free ESRI Global Account to view this seminar.
