[deep sigh] After being let down again, I call upon the powers of the network: Does anybody have an inflatable planetarium they would be willing to bring (or lend) to @emfcamp.bsky.social?

This article is in the paper copy of the FT today, which is nice :) Quite chuffed that my little data analysis project has ended up in a national newspaper. And I think it's an important topic too. #uk #health #pharmacy #data #datanalysis

Did you know that the number of pharmacies in England open after 9pm has decreased by 95% in just three years? I did some data analysis on this, inspired by needing an out of hours pharmacy over Christmas, and it has been featured in the Financial Times today: as.ft.com/r/4333cab1-6...

Very proud of my former student (now colleague!), Gabi, who just gave her first conference presentation at #foss4guk in Leeds. #geospatial #gis #osgeo #postgis

The new 'gdal raster neighbours' function is pretty cool - it does convolution across a raster, with configurable kernels and other options. Not yet released, but available in dev builds. See gdal.org/en/latest/pr... for details.

Looking forward to #foss4guk this week in Leeds. I'll be attending with a colleague, running a workshop on producing live vector tiles from PostGIS and my colleague will be giving a talk. Now just to hope that the trains work better than last year: I got stuck in Bristol TM because the lift broke!

Debated about buying some heavy water today...for my #emfcamp talk/demo but a) it's very expensive and b) it'd probably get me put on a list. I'm consoling myself by buying high wattage halogen lamps instead.

@pwramsey.bsky.social and I are hosting PostGIS Day again this year! The call for papers and registration is open now. Join us! www.snowflake.com/postgis-day-...

PostGIS Day | November 20

Learn how others are making use of PostGIS, pick up some tips and tricks, and share stories about bringing this excellent tool into your organizations.

Does anyone know any good books about the UK telephone network? Ideally I'd be interested in a history of the network, exchange development, memories of working on the network, big events (eg. phONEday etc) - but I can't seem to find anything like this

Orbio Earth just open-sourced their full methane detection pipeline—models, tools, synthetic-plume engine & validation notebooks—for Sentinel-2, Landsat 8/9, and EMIT. #Methane #ClimateTech #OpenSource - orbio-earth.github.io/Project-Euca...

So, TIL that a MultiPolygon is invalid if any of its polygon parts touch at more than a single point. Eg. a MultiPolygon where two 'polygon parts' share an edge is invalid. I can see why this is the case - those two polygon parts should be merged, but it's a bit annoying. #gis

I won't be able to make this as my wife is in the US at the time and so I'm needed at home - but I've had a great time at PyCon UK in the past, and I'm already looking forward to watching the videos of some of these talks.

Pleased to announce that I'll be giving a workshop at #foss4guk entitled 'Live Vector Tiles from PostGIS with pg_tileserv: A Hands-on Workshop' - I'll take you through the full process of using pg_tileserv to serve vector tiles to web maps (using MapLibre, Leaflet etc) and QGIS. Come along!

The Placing Technology blog (placing.technology) is utterly fascinating - someone blogging parts of their PhD research about the history of GIS and geospatial technologies in general.

The bubble mixture recipe for big bubbles on this blog is awesome - easy to make and works far better than others I've tried in the past! juliawise.net/misc-parenti... Thanks @juliawise.bsky.social

Just reviewed the list of talks/workshops for #foss4g2025 in Auckland - there are loads of really cool submissions. Such a shame I won't be able to be there, but I'll look forward to the videos. You can review them too at 2025.foss4g.org/attend/call-... Very simple to review, just 4 options!

We are finally ready to announce that EMF 2026 will happen on July 16-19, 2026, at Eastnor Castle Deer Park, Herefordshire. Expect more updates soon as we start spinning up the organisation again.

Surprised to find out today that my talk on UK railway signalling at #emfcamp from a few years ago has now had over 3,500 views! It's at www.youtube.com/watch?v=cryU... if you'd like to watch it.

🚨 Alert. Alert. The closing date for presentation submissions for #FOSS4GUK is rapidly approaching. Submit your talks here: uk.osgeo.org/foss4guk2025... It can be opinions, about projects, new ideas, breaking down technical concepts. Whatever topic you want, just involve open geospatial!

Found a cool feature of ogr2ogr: you can use SQL like 'SELECT * EXCEPT (col1, col2) FROM table' with the -sql parameter to exclude a few fields from the conversion process. Handy when you've got lots of fields and don't want to list them all out in the SELECT. See gdal.org/en/stable/us... #gis #gdal

Thinking of proposing a workshop at FOSS4G UK 2025 on on-the-fly tile generation for webmaps. Could cover MVT generation using PostGIS and pg_tileserv, raster tile generation using Titiler etc, or both? Any preferences? Or particular things I should cover? #foss4g #foss4guk #osgeo #gis

Just bought my ticket for @uk.osgeo.org's FOSS4G UK conference in October. Excited to attend on behalf of Rebalance Earth, and with some colleagues. Now just to write my workshop proposal... #gis #foss4g
