Last week Earth Resource Mapping announced it had made its source code for read/write of its ECW and the ISO standard JPEG 2000 available under GPL-style licensing. Essentially, the code is available for use in any GPL-style application (that is, one not for sale, among other things). ThatТs a pretty big step for a small company wrangling for space in the image compression marketplace with LizardTech, Luratech and others. ERM was an early watcher and supporter of JPEG 2000 and has provided developer friendly licensing of its products for some years. The open source GIS community will be happy to see this level of support. I hope to see ERM at the Open Source GIS conference this spring in Minneapolis.

Siemens has introduced its own SMS schema to Уleave notesФ attached to locations. The notes (text, images) actually live on a server, and when a device УopenФ to receiving them, crosses in the defined area, the message it delivered. ThereТs been discussion of, and demonstration of this concept for at least the last few years. This one includes an Уon/offФ switch to help prevent SPAM and unrequested advertising. The technology is two years from rollout according an article in PC World.

This idea hasn’t excited me, though perhaps I don’t fully see the value just yet. That said, just recently, I found an interesting application for it. I was running with some friends across Boston and we all agreed we didn’t really know where the “bad” parts of town were. Might be nice to have those “noted” by someone who knows the area to help us stay out of trouble. If we cross a geofence, a warning might appear. Or better yet, such notes migh help us stay on a planned route.

Update (2/14): A second article notes a trial by a German newspaper. The testers found that they could not leave messages and that the system was slow at times. The testers could however, locate each other.
