Eye-Fi introduced a set of SD cards that will geotag photos (without a GPS). It's offered at different price levels depending on what you want to do with the resulting photos: least expensive ($79) - upload to computer via home Wi-Fi, next expensive ($99) - upload directly to computer or favorite websites like Flickr wirelessly, most expensive ($129) geotag photos and upload wirelessly via WayPoint. How does the geotagging it work? When you shot a picture, the card stores information about local Wi-Fi sites. Then, when the photos are uploaded, they get geocoded by comparing that information with Skyhook's maps. (press release on Explore, the one with geotagging, press release on family, Wired interview with Eye-Fy CEO)
Impact: 4 This could be one option for field staff to capture and quickly, if not immediately, send back geocoded imagery. While not GPS accurate, it works indoors and with any SD using camera.

EveryScape, the folks who offer their own version of street level photos a la StreetView have announced two kinds annotation capabilities. The first, for businesses, called World Tags allows for uploaded content about the company. Businesses will need to contact the company to set these up. The second, Scape Memos, is for everyone - post whatever text you like on the images - and you receive a URL that links to the image and the message. (press release (pending), Xconomy article) The company has also announced new partnering options for those who what to capture street images and professional photographers to capture indoor details.
Impact: 3 Could this be used for tagging needed city improvements, such as broken sidewalks? Are citizens more likely to tag such things on pictures vs maps or aerial imagery? Could/would field techs leave notes for one another? Could Scape Memos become part of work orders for the trades that are on the move?

Rhiza’s Labs Community Insight is not noted on the company website (save that it's being introduced at Where) [update: it is now, pr here, too] but here's what Rafe Needleman at WebWare understood it to be: "a Web-based platform for mapping data sets. It lets users compare data sets on a map, annotate existing maps, and also lets the users who upload data see what other maps use their data." Not sure what that means, though the app, per the company is "a platform for sharing complex map data, creating data analysis online, and networking with experts. It is designed to be accessible and usable by policy wonks, concerned citizens, and academic researchers alike. The product is being used in conservation science on databasin.org to connect policy advocates with science data, where issues of trust, provenance, and accuracy abound." Still a bit fuzzy.
Impact: ? Hard to judge at this time.

Placebase, the folks behind PushPin, the mapping API akin to Google's but without the restrictions and more contral, is said (per Needleman above) to be offering a free API and humanly decipherable URLs for maps.
Impact: 2 As much as I like the platform, there are already too many free mapping APIs out there (did anyone notice Mapquest's?) and as we learned at Location Intelligence, everyone (professionals and consumers) want something familiar - Google Maps and increasingly, Virtual Earth. I do hope I'm wrong, though.

Concharto is Google Maps mashup that allows users to add notations - the twist - each one has a time code. So, for searches you get three boxes: where, when and what.
Impact: 2 Cool idea. I suspect what will happen is that those apps that need time codes will add them. Sites that track weather, disease, even news manage time already.
