STAC Extensions and 0.6.2 Release

First up is the 0.6.2 release. Similar to the 0.6.1 release, it is mostly some small ‘fixes’: updated examples, spec language that wasn’t quite right, and updating the implementation page to link to more catalogs. Plus, we improved our JSON Schemas — for stricter checking of version numbers and compatibility with the last JSON Schema specs. But, we did decide that ‘minor’ releases like this one could include additional STAC extensions, as those right now are more of a community where ideas evolve. Thus, in this release, we are adding in 4 new extensions, which are all in ‘proposal’ status of our Extension Maturity classification. This means that they are solid ideas seeking more input from real-world implementations. As extensions get more implementations and testing, it will move up the maturity classification to become stable extensions that everyone can rely upon.

SpatioTemporal Asset Catalog (STAC) Community Advances and 0.6.1 Release

Though we’ve been quiet on public forums, the momentum on SpatioTemporal Asset Catalogs (STAC) continues to grow. I’m quite pleased by the latest advances, as it is almost all real-world implementation work that is driving improvements to the specification by grappling with large and diverse catalogs. The community has also been expanding to more types of data, which is quite exciting to see.

Cloud Optimized GeoTIFF Advances

The last month has seen a number of great Cloud Optimized GeoTIFF advances, with lots of enthusiasm at the FOSS4G-NA conference. There’s new software supporting COG’s, a new logo, a new mailing list set up for collaboration, and some great ideas of how to make COG’s more useful by surfacing best practices and making the spec a wee bit more formal.

Cloud Optimized GeoTIFF Birds of a Feather at FOSS4G-NA

FOSS4G North America was a great time, and there was a lot of enthusiasm for Cloud Optimized GeoTIFF’s. I shared a number of the cool new examples in my keynote, and then Eugene from Azavea gave a really great overview of the format, along with a number of best practices learned as he implemented it in GeoTrellis and RasterFoundry. It was standing room only for Eugene, in an already quite large room, so was quite cool to see so many people interested in COG.

COG Map and tiles.rdnt.io

The Cloud Optimized GeoTIFF (COG) revolution marches on! I wanted to share a couple cool projects that we’ve been working on to help demonstrate the power of COG’s. The first is called COG Map, and it’s my first real coding project in over a decade, so I’m pretty proud of it. My Technical Fellowship at Radiant.Earth supports me to push forward standards and infrastructure for Cloud Optimized GeoTIFF’s and SpatioTemporal Asset Catalogs.
