Re: [gdal-dev] How to build STAC of local raster files?

For creating STAC Items you can look at https://github.com/developmentseed/rio-stac (disclaimer I’m the author), you can also have a look at https://github.com/stac-utils/pystac for creating items and catalog Here is a quick how to about how to create items and collection and ingesting them to

Re: [gdal-dev] Enabling default compression for COG ?

+1 I think it’s reasonable to have a default compression. In rio-cogeo I’ve set the default to `DEFLATE` but that’s was a personal preference. Vincent > On Sep 30, 2021, at 3:46 PM, Even Rouault wrote: > > Hi, > > should we enable a default compression scheme for the COG driver ? I've heard

[gdal-dev] Supported Overview resampling for COG

Bonjour/Hi, While I was working on https://github.com/mapbox/rasterio/issues/2153 (add missing RMS resampling method for overviews in rasterio) I wanted to double check which resampling methods were actually supported. In gdaladdo, the doc says

Re: [gdal-dev] Prevent GDAL reads for .aux or any other s3 objects that do not exist

Hi Darren You can do this by setting `GDAL_DISABLE_READDIR_ON_OPEN=EMPTY_DIR` or by narrowing the allowed extension with "CPL_VSIL_CURL_ALLOWED_EXTENSIONS=.tif" Kyle is working on some docs that explains those env in TiTiler: - https://github.com/developmentseed/titiler/blob/0a5288de30845865256

Re: [gdal-dev] COG - RGBI

I guess you mean RGB and I for Infra-red ? Anyway the answer will be NO. JPEG only allow 3 bands + a bit mask (same for Webp). For raster with more than 3 bands there is no real option to get compression (with loss) as high as with JPEG or WEBP . > Le 8 mai 2020 à 15:08, Travis Kirstine a éc

Dear GDAL devs, Maybe this is a totally dumb question and there might be already a doc somewhere (which I couldn’t find), but what are the min (and or max?) PROJ version for let say gdal2.4 / gdal3.0 / gdal3.1 ? Regards, Vincent ___ gdal-dev mailing

Re: [gdal-dev] Faster gdalinfo from COG

Hi Jukka, The time you are seeing is related to your configuration and not specifically to the file itself. If you set `GDAL_DISABLE_READDIR_ON_OPEN=EMPTY_DIR` in your env, you’ll see that gdalinfo will be much faster. ``` $ time GDAL_DISABLE_READDIR_ON_OPEN=EMPTY_DIR gdalinfo /vsicurl/http:

Thanks Even, Just a quick note. By reading the docs it seems the overviews will be created by default except if OVERVIEWS=FORCE_USE_EXISTING is set and if the input file doesn’t have overviews. The specs make overviews optional thus the OVERVIEWS option usage seems a bit odd. TBH, I’m 100% wi

[gdal-dev] VRT and COG

Goal: I’d like to see if there could be a way to use VRT of COG to create a mbtile like system to read tiles. If I remember well when a VRT points to COG you still need to create external overviews for the whole VRT because it won’t fetch de overviews from the COG itself when trying decimated
