 das-g | (and, at least until now, of nothing else in nixpkgs) | 19:15:05 |
| das-g | ili2c is a part of the Interlis ecosystem. While Interlis is a general data modelling language (and collection of data formats both for the model metadata and for the such-modelled data itself), it's focus is on modelling and transferring spatial data, which is also reflected by its slogan/tagline "The GeoLanguage". | 21:28:22 |
 nh2 | I'm at the GeoWeek 2024 currently (my startup benaco.com is exhibiting with a booth), and I just talked with Howard Butler, devleoper of PDAL :) Greetings to the Nix geospatial community | 22:07:01 |
 Ivan Mincik (imincik) | In reply to @nh2:matrix.orgNice to hear from you. Good luck with your exhibition! Greetings to hobu as well. | 22:12:20 |

 l0b0 | Got a tip from a colleague which might lead to a fix of the missing LERC compression in GDAL. Basically, -DGDAL_USE_INTERNAL_LIBS=OFF means we have to specify all the corresponding variables to include the libraries in other variables. | 01:18:03 |
| l0b0 | In the meantime I'd really appreciate a review of a prep PR which enables devs to run each of the GDAL tests separately. | 01:19:03 |

| Ivan Mincik (imincik) | I spent some time on fixing #238882 , but it looked to me as some kind of bug or problem on GDAL side. I was not able to find any problem in our packaging. l0b0 , have you seen it working (is for example Debian package or GDAL docker image working as expected ?) | 15:27:53 |
| l0b0 | In reply to @imincik:matrix.orgI've only ever seen it work with the internal library, such as in this documentation. I guess most people (including distro maintainers) don't care too much about vendoring these libraries, but this video talks about why NixOS maintainers in particular should care. | 19:24:53 |
| Ivan Mincik (imincik) | What about opening issue in GDAL ? | 19:26:23 |
| Ivan Mincik (imincik) | So many issues in those few instructions in elevation README :) | 19:31:00 |
| Ivan Mincik (imincik) | Good reminder why I use Nix | 19:34:49 |
| Ivan Mincik (imincik) | Please review this trivial patch version update - https://github.com/NixOS/nixpkgs/pull/286713 . Thanks. | 21:04:05 |
| l0b0 | In reply to @imincik:matrix.orgThe first thing someone is going to ask is how to reproduce, and I think I'll need some help with that. There are a bajillion options, and I'm not very familiar with cmake, and even less familiar with GDAL. | 23:46:11 |

There are a bajillion options, and I'm not very familiar with cmake, and even less familiar with GDAL. I'd be surprised if they'd be OK with running nix-build to test it, but I could start with that. | 23:46:58 |
| l0b0 | Looks like there's already a relevant issue. | 23:48:01 |
| l0b0 | * Looks like there's already a relevant issue. I'll try building libtiff with lerc to see if that fixes it… | 23:50:47 |

| l0b0 | Is anyone familiar enough with libtiff to create some tests? I feel like if LERC support should be added to libtiff then it should be tested in the libtiff package, not in GDAL. | 00:05:25 |
| Ivan Mincik (imincik) | In reply to @vengmark2:matrix.orgIs it working with https://github.com/NixOS/nixpkgs/pull/290556 | 09:17:53 |

| l0b0 | Yep, that's how I verified the libtiff change. There's no libtiff test to verify that LERC support has been enabled yet. | 09:18:44 |
| l0b0 | You should be able to verify with | 09:24:05 |

| l0b0 | * You should be able to verify with (It takes forever to build, though.) | 09:25:13 |
| Ivan Mincik (imincik) | What about trying | 09:25:42 |
| Ivan Mincik (imincik) | tiffinfo contains Compression Scheme: None field | 09:26:26 |
| l0b0 | I did verify using that, but I don't know of any good TIFFs I could use for the test. Ideally I'd use libtiff to create a 1x1 LERC TIFF and then read its info, but libtiff doesn't seem to come with CLI tools to create TIFFs. | 09:26:50 |
