Nice to see the USGIF levereraging the Web2.0 and social media to connect with people as the organization has rolled out a few new social networking resources this week to coincide with the annual GeoInt event. Most noteworthy is a new blog – Got Geoint. There’s also a facebook group and a Twitter page (@gotgeoint)

Today’s Geo news round-up from GISuser Today is now online and can be found HERE. From this edition… Oh those pesky “page cannot be found” errors.. don’t they drive you nuts? I know they make me crazy, particularly when I get them from State GIS Data clearinghouses and data repositories. The most popular features of GISuser.com are all the free data articles and pointers, however, as time goes by many links become out of date – just search around on some of these links in this TOP read article and you’ll see what I mean! So, as a solution I’ve decided to start updating our GISuser Free Data spotlights, starting today with the State of Alabama. See the spotlight below to locate the best places on the web to grab free, downloadable GIS data products including DRGs, DOQs, aerial photos, PLS data and more – and remember, please don’t buy these data from the online depots that sell/resell free data – chances are you’ll be getting old products, sans metadata etc… oh, and please be sure to provide me tips or pointers if you feel I’ve missed something.
A reminder, I really dig sharing data resources with readers, mainly because these portals tend to come and go and locating the data you need can be a challenge. Most recently I’ve featured a tip about the MRLC. The Multi-Resolution Land Characteristics (MRLC) Consortium is a group of federal agencies who first joined together in 1993 (MRLC 1992) to purchase Landsat 5 imagery for the conterminous U.S. and to develop a land cover dataset called the National Land Cover Dataset (NLCD 1992). In 1999, a second-generation MRLC consortium was formed to purchase three dates of Landsat 7 imagery for the entire United States (MRLC 2001) and to coordinate the production of a comprehensive land cover database for the nation called the National Land Cover Database (NLCD 2001). These data are now available via FTP download. See more on here
News out of GeoInt this week as Flight Landata has introduced their Dual-Swath BuckEye EO system. The new Dual-Swath configuration of BuckEye provides a 78-megapixel imaging capability with centimeter-level spatial resolution. Larger collection areas per flight line mean the aircraft is in the air for shorter periods during acquisition or it can cover a greater area in a given time. See more on this cool technology here
