The GeoPDF blog has a lengthy explanation behind the recent decision to submit the format to OGC. Be sure to visit their page for the full details. Here is a snippet from their summary : "I've been asked here and elsewhere, "what is the link between the submission of GeoPDF to OGC and Adobe's geospatial extensions in Acrobat and Reader 9.0?" There is a link, to be sure, but the primary reason that TerraGo has submitted its legacy georegistration technique to OGC is our customers demanded it. There are terabytes (petabytes?) of GeoPDF files out there that use the technique and they wanted to be confident that their investment was secure. That's quite reasonable by any measure. It would be one thing to just post a specification for the technique, a la ESRI's shape file spec [PDF], but wouldn't carry the imprimatur of a standards organization that our customers demand."

In a surprising bit of news today, the GeoPDF blog is reporting that TerraGo has submitted the GeoPDF Spec. to the OGC. Here is a snippet of the announcement from the GeoPDF blog :“Today’s announcement further demonstrates our commitment to meeting the needs of our customers who require software solutions that leverage open standards,” said Patrick Graves, chief software architect at TerraGo Technologies. “By opening the GeoPDF specification through the OGC, the large number of maps and images that have been published in GeoPDF format by our customers can now be accessed by the entire geospatial community.”
OGC Geospatial Search Summit
[+]
The High Earth Orbit offers a nice short summary of his participation to the OGC Geospatial Search Summit. See also this previous story on geo-enabling OpenSearch.org. From the HEO entry: "A couple of interesting agreements came out of the meeting. Foremost was the understanding for guidance of using simple, common formats as they already exist when appropriate. This means using OpenSearch as a base URI templating mechanism and follow GeoRSS-Simple specification for geographic data. Of course, a format can expand upon this and offer more complex formats that conform to more complex specs. But by at least providing a common baseline means that almost any service can easily interconnect with another service."
OGC Approves GeoPDF 2.2
[+]
From the GeoPDF blog : "GeoPDF 2.2 OGC 08-139r1 was approved as OGC Best Practice. Personally, I think that the use of GeoPDF was unfortunate, for various reasons, but I'm happy to see the georegistration technique published. If you'd like to roll-your-own geospatial PDF, I'd recommend using Adobe's proposed geospatial extensions to ISO 32000. Our software supports this georegistration technique, and we're already moving in that direction."
This is actually big news. The ISO standard won't officially get passed for a few more years, so this will be what people use for quite a while.
