Assumptions in Remote Sensing

Back in 2012, I wrote the following editorial for SENSED, the magazine of the Remote Sensing and Photogrammetry Society. I found it recently while looking through back issues, and thought it deserved a wider audience, as it is still very relevant. I’ve made a few updates to the text, but it is mostly as published. […]

Cloud frequency map for Europe & update to cloud frequency web app

I’ve posted before about the cloud frequency map that I created using Google Earth Engine. This post is just a quick update to mention a couple of changes. Firstly, I’ve produced some nice pretty maps of the data from 2017 over Europe and the UK respectively. I posted the Europe one to the DataIsBeautiful subreddit […]

Attending EGU in a wheelchair

This is an old post that I found stuck in my ‘drafts’ folder – somehow I never got round to clicking ‘publish’. I attended EGU in 2016, and haven’t been back since – so things may have changed. However, I suspect that the majority of this post is still correct. Right, so, in case you […]


I really enjoy reading blogs. That seems to be a slightly outdated view, as many people have moved over to using Twitter exclusively, but I like being able to follow everything that a specific person writes, and seeing mostly long-form articles rather than off-the-cuff comments. Back in the day, when blogs were really popular, every […]

Some recent papers of mine

I’ve just realised that I haven’t posted about the last few papers that I’ve authored. Some of these came from before I stopped paid work due to ill-health, and some were based on work that was done before I stopped work, but have only been published since. Anyway, on with the papers: Rapid and near […]

Roadside leafiness from space – Part 2

In the last post in this series, I showed some pretty maps of roadside leafiness, created by extracting NDVI values near roads – like this: This time, I want to move away from pretty images to some numerical analysis – and also move from a local scale to a national scale. My first question was: […]

Roadside leafiness from space – Part 1

If you just want to see some pretty maps of roadside leafiness then scroll down…otherwise, start at the top to find out how I did this. I’ve recently started doing a little bit of satellite imaging work again, and started off with a project that was inspired by a post on James O’Connor’s blog. He […]

Quick way to delete columns from a shapefile

I haven’t posted anything on this blog for a long time – sorry about that. I’ve been quite ill, and had a new baby – so blogging hasn’t been my top priority. Hopefully I’ll manage some slightly more regular posts now. Anyway, on with the post… I recently needed to delete some attribute columns from a […]

Showing code changes when teaching

A key – but challenging – part of learning to program is moving from writing technically-correct code “that works” to writing high-quality code that is sensibly decomposed into functions, generically-applicable and generally “good”. Indeed, you could say that this is exactly what Software Carpentry is about – taking you from someone bodging together a few […]
