Robin Wilson    A quick post today to talk about a couple of PostGIS functions I learnt recently. I had a CSV file that contained well known binary WKB representations of geometries, stored as hexadecimal strings. I imported the CSV into a PostGIS database, and wanted to convert these to be proper PostGIS...

Robin Wilson    It’s been a while since I posted here I kind of lost momentum over the summer which is a busy time with a school aged child and never really picked it up again. Anyway, I wanted to write a quick post to tell people that I won two awards at the British Cartographic Society awards

Robin Wilson    Summary: I’ve created a demo web app where you can search an aerial photo of Southampton, UK using text queries such as roundabout , tennis court or ship .

It has a somewhat niche use case, but it seems like a few people have found it useful. In brief, it allows you to use the folium package for creating interactive maps from Python, but without an...

Robin Wilson    I realised recently that I’d never actually blogged about my pyAURN package so it’s about time that I did. When doing some freelance work on air quality a while back, I wanted an easy way to access UK air quality from the Automatic Urban and Rural Network AURN . Unfortunately, there isn’t a nice...

Robin Wilson    I was recently trying to set up RasterVision on my Apple Silicon Mac specifically a M MacBook Pro, but I’m pretty sure this applies to any Apple Silicon Mac . It all went fine until it came time to install the triangle package, when I got an error. The error output is fairly long, but the

Robin Wilson    For a while I’d wished there was an easy way to get notified when my favourite open source packages release a new version. I’d often see something on social media, but that tended to only be for the larger packages and I wanted to keep up with the smaller ones too. When I actually bothered
