@GregCocks this is useful especially if her newsletter is on hiatus for the summer I believe.

Hey GIS mapping friends. I was a StoryMaps user for years for blogs, but the platform went away and I can't migrate to ArcGIS because I use a Chromebook (it's all I need).

BTW, everything I ever wrote has been deleted.

What do you think of Felt? It seems built for online-only users like me. I can embed the map into most blog platforms.

tagging conundrum for LoRaWAN remote utility meter reading base stations (Part 2)

Add-on to an existing street light pole.
This is a bit harder as it is both a street light, AND a base station:

highway=street_lamp
lamp_mount=straight_mast
lamp_type=LED
utility=water
communication:lorawan=yes ?
utility=water
operator=Northumbrian Water Limited
operator:wikidata=Q7059853

Any suggestions please?

I've saved off climate.gov/data/ but it's ~70GB and I don't have any way to personally host files that big.

@lostmonkey nice! I hope to map public art in my area too. This is a great resource.

Visiting Aarhus and up for an art walk?

Here is a uMap showing the murals from the 17 Walls project – plus many other mural locations in the city (that are mapped in OpenStreetMap). A great way to explore Denmark’s second-largest city through public art.

Got a #qgis question for you, #gischat.

I'm working with some buffers, and I'm looking for areas of overlap, and how many overlap in a given area.

Current process is:

Buffer → Split by Lines → Drop Duplicate Geometries → Spatial Join from the splits to the original buffers, counting.

The result works, and I can identify areas with the most overlaps. But for anything more than a handful of input features, the process slows to a crawl during "split by lines".

Any ideas?

Starting a blog post trilogy on 'GeoTIFFs to GPUs'! If you've struggled with using GDAL effectively in GPU workflows (read: machine learning pipelines), and/or have messed around with converting to other file formats because you thought 'GeoTIFF is slow', know that it doesn't have to be this way!

I'm working towards GPU-based decoding of Cloud-optimized GeoTIFFs into CUDA/GPU memory via Rust/FFI. Eventual goal is to do zero-copy to CuPy arrays on the Python side via DLPack. It'll be a few months of work, but let's start from part one:

ICYMI: In September 2024, The Carpentries submitted a proposal for 1.5 million USD to the U.S. National Science Foundation (NSF) Pathways to Enable Open-Source Ecosystems (POSE) Program, and were extremely pleased to learn that the proposal was recommended for funding.

However, we have had to rescind our proposal because it was flagged for DEI content, namely, for “the retention of underrepresented students, which has a limitation or preference in outreach, recruitment, participation that is not aligned to NSF priorities.”

Since we are no longer in the running for this funding, we are actively seeking donors and a cohort of funders who align with our mission and core values and want to support our work.

Find out in this blog post announcement how you can help us by making a recurring donation, or reaching out to potential donors on our behalf, or connecting us with potential donors and program officers, or collaborating with us to apply for grants, and many other ways you can support our mission: carpentries.org/blog/2025/06/a
