since GDAL 3.7 we can use vrt:// protocol with raster file/urls to apply many operations available to gdal_translate
so "vrt:///vsicurl/https://hella/big/raster.tif?outsize=10%,10%&expand=rgb" would on-the-fly produce VRT that decimates and expands a palette image to full RGB (watch out for special & etc use quotes)

works the same in cli or qgis or any R or Python package that uses GDAL

see doc for available args (note that vrt:// since 3.1 supported "bands=i,j,k")

I updated the interactive visualization of the density of occurrences on @gbif for different taxonomic groups with the latest data from May 1.

Now with over 2.9B occurrences!

@mariohamann Here: github.com/glaroc/arbres-mtl-r . It's still very much a work and progress and nothing is documented or commented yet.

I challenged myself to redesign the map of public trees of Montreal using a completely open source and serverless approach. Here it is, thanks to

This is still a work-in-progress but all feedback is welcome.

Would anyone know how to create a sub catalog to an existing catalog through the STAC API ? collections and items can be added through POST requests, but what about catalogs? #stacspec #opensourcegeospatial #cloudoptimizedgeospatial

@eliocamp Assuming people know what are both kinds of lists when they are searching for the meaning of lists.

Using the word "list" to define lists.

Since this is a basic R function, words like coerce might also be avoided. Somebody searching for this definition might not be a experimented user.

@eliocamp @rstats . The definition for list() is "Functions to construct, coerce and check for both kinds of R lists." Needless to say this is not a very useful definition and means nothing to most people.

It turns out Geopackage is a much more capable format for the cloud than I originally thought. With a proper spatial index, or by creating a non-spatial index with ogrinfo -sql, it's quite easy to /vsicurl to a large cloud-hosted gpkg and only get what you need from it!

Through random requests, you can extract elements using a spatial window, the fid of a feature or an SQL query on indexed non-spatial columns. This is more flexible than other #cloudnativegeospatial formats I have tried.

CTRL-D gets you out gracefully of bash, Python, Julia, R, PostgreSQL, MySQL, and most other terminal-based software.

Vim and Nano are still stuck in the kitchen talking to Dave about his transformer collection.

Is that what we call reverse taxonomic geocoding ?
