SpatialistsPython #uv: uv by #Astral (also behind Ruff) is a new-ish #Python project management tool that you may have already heard praise about. uv simplifies environment and dependency management for Python (truly, finally) and is blazingly fast, thus potentially streamlining also geospatial workflows reliant on libraries such as #GeoPandas, #rasterio and the like.

Python uv – spatialists.ch – geospatial news
#uv is a relatively new #Python project management tool that has been gaining attention for its ease-of-use and speed. It has quickly become a popular choice for easy installation and environment and dependency management in Python projects.
Anita Graser 🇪🇺🇺🇦🇬🇪👀 Is anyone of you aware of a python solution for creating a bivariate map from a raster?
Olivier D'Hondt 🛰️🌍🌱I had a quite interesting experience with #rasterio. Opening a dataset with a context only once outside of a loop resulted in slower execution than opening it at every iteration. I need to investigate that.

stevefaeembraBeen working on bringing back an old Python project, to get OBJ files from GeoTIFFs using #RasterIo.
Mostly for my own amusement, and to get back to doing some Python after a break.

The odd dark spike to the south was the crane being used to build the Virgin Hotel in Cowgate, the DSM is from a couple of years back.
One cool feature of rasterio, inherited from gdal, is that if you write a raster to a dataset of a different size, it will automatically resample your image to the size of the destination.

Sean GilliesFor the adventurous there is a #rasterio 1.4 pre-release on PyPI now. https://pypi.org/project/rasterio/1.4a1/ https://github.com/rasterio/rasterio/blob/rel-1.4a1/CHANGES.txt#L4 #python #gis
Keith JenkinsI've been struggling with adding a colormap to a landcover raster. There is https://gdal.org/programs/gdalattachpct.html but apparently it isn't included in the GDAL that comes with QGIS or osgeo4win.
I finally tried using #rasterio, and and am happy to report that it works like a charm! https://rasterio.readthedocs.io/en/stable/topics/color.html#writing-colormaps
