I am pleased to announce the release of PDAL 2.9.0

https://github.com/PDAL/PDAL/releases/tag/2.9.0

Key goodies include GDAL VSI support by Norman Barker, FileSpec support by Thomas Swamy, filters.supervoxel by Bram Ton, SPZ read/write by Isaac Bell, `ogr` option for filtering to a number of stages by Isaac Bell, and greatly enhanced readers.tindex support by Isaac Bell (see https://pdal.io/en/latest/tutorial/tindex/ for usage).

Conda packages will be catching up. Thanks again to every contributor!

Investment just paid off 🙂

Another round of user friendliness for "gdal" CLI. Now "gdal raster/vector reproject input_dataset --dst-crs=EPSG:<TAB><TAB>" will only list CRS that intersect the extent of the dataset: https://github.com/OSGeo/gdal/pull/12573

AI garbage tries to go into libtiff: https://gitlab.com/libtiff/libtiff/-/merge_requests/734

It took some time to reach that point, but now the GDAL Sanitizer (Address / Undefined behavior / Leak) CI target runs cleanly and can now spot any such issues as soon as they are introduced and before they are merged: https://github.com/OSGeo/gdal/pull/12562

@gdal We've had up to 265 attendees following the webinar about the GDAL CLI Modernization. You'll find the slide deck at https://download.osgeo.org/gdal/presentations/GDAL%20CLI%20Modernization.pdf , including a best-of of the Q/A session, and the video recording at https://www.youtube.com/watch?v=ZKdrYm3TiBU

@jjimenezshaw Follow-up contest. Craft the smallest GeoPackage file (raster, vector or both... or none) that passes the OGC GeoPackage 1.2 Conformance Test suite (and can be opened by GDAL). My curent record: 3584 bytes . As there are different solutions that reach that size, bonus point for the smallest .gpkg.zip file (at deflate level 9 compression). My record: 708 bytes

@jjimenezshaw Ah ah, ok here's my finding. No, it's not a TIFF, but an 3 line PGM file (actually just the header):
P5
2147483647 2147483647

In 2 hours from now, that is at 14:00 UTC, the @gdal team will hold a "GDAL CLI Deep Dive" webinar. Join us at Join us at https://numfocus-org.zoom.us/webinar/register/WN_oW6mA6DNSKe8FUTm1-tkRQ#/registration

Quite excited by the new artihmetic #GDAL band on-the-fly capabilities of https://github.com/OSGeo/gdal/pull/12507

```python
with gdal.Open("rgb.tif") as ds:
R = ds.GetRasterBand(1)
G = ds.GetRasterBand(2)
B = ds.GetRasterBand(3)
gray = (0.299 * R + 0.587 * G + 0.114 * B).as_type(gdal.GDT_Byte)
gdal.GetDriverByName("GTiff").CreateCopy("gray.tif", gray)
```

The new GDAL 3.11 CLI has context-aware bash completion and spelling suggestions – options, formats, sub-commands, and more! No more fumbling for inconsistent names or orderings.

Join us at the GDAL CLI Deep Dive webinar on June 3rd at 1400 UTC to learn more. https://numfocus-org.zoom.us/webinar/register/WN_oW6mA6DNSKe8FUTm1-tkRQ#/registration

Fun #GDAL contest. Craft the smallest file (in terms of byte size) that is recognized (opened by GDAL, using any official driver of your choice) with 2147483647 x 2147483647 raster size. My current record is 27 bytes. Any improvement over that?

411 people signed up so far. Come join us next week to learn about the new CLI. https://mastodon.social/@gdal/114495783671804297

@JensWiesehahn Possibly, with extra work. Would require a --radius argument and tuning how we format inputs to our expression parser(s)

@tim_salabim The PROJ team (actually @jjimenezshaw ) maintains a similar service at spatialreference.org :

"The Open Geospatial Consortium (OGC) invites you to participate in the AI-DGGS Pilot — a cutting-edge initiative at the intersection of Artificial Intelligence (AI) and Discrete Global Grid Systems (DGGS)." Is that legit email or some spam ? Because mixing two tricky subjects, taken separately, doesn't seem like a good idea

I agree with @hobu that commercial cloud providers should help us maintain the code that provides easy way to use the resource they provide to their customers. If you are a customer of those commercial cloud providers and make an heavy user of @gdal on them, please reach to their sale representatives and help us make a case for their continued sponsorhip.

🌍 Circular arcs in QGIS are crucial for precise geographic data! Currently, support is limited, but you can help change that. With our crowdfunding campaign, we aim to enhance their management in GEOS for reliable processing, precise intersections, and new possibilities. We’re halfway there, and we need your help to go all the way! 🚀

@autra still waiting for a feedback from MITRE

The GDAL package in conda-forge has now support for JPEGXL and JPEGXL-in-TIFF
