Background Following on from my blog posting from July 2023 ‘Snowpatches and satellites‘, I have been involved in some technical development work using Earth Observation (EO) technologies and satellite imagery. For many years I have monitored and observed long-lasting snowpatches in the Scottish mountains, and as mentioned in the previous blog posting, I have carried… Read more »

Snowpatches and satellites
Overview For many years, the extent of snow cover in the Scottish Highlands has been recorded and documented by groups of ground-based observers from a volunteer community of ‘citizen scientists’. This winter snow cover melts in the spring and summer months, leaving behind remnant snowpatches, some of which have shown themselves to be ‘perennial’, lasting… Read more »
What is the “truth” in COVID-19 data?
1. Truth in Data In a blog posting from April 2020, I discussed the development of a visualisation of data related to the global COVID-19 pandemic. In the comments below the blog posting, I mentioned that there are several issues with the data in terms of accuracy and what the ‘truth’ of the data actually… Read more »
A GIS visualisation of the COVID-19 pandemic
One thing that has become noticeable in the current COVID-19 pandemic is a plethora of web-based visualisations about the impact of the virus. Most of these are line graphs showing exponential or vaguely bell-shaped curves and peaks typical of mathematical models of the spread of diseases. Many of these visualisations show the spatial, or… Read more »
GIS MSc – part two
The three-year part-time remote learning UNIGIS UK MSc course I recently finished had two very different components – the first two years consisted of teaching modules of learning materials and assessed assignments (see my earlier blog posting about this here), and the third year involved the planning, development and writing of a dissertation, which is… Read more »
GIS MSc – part one
I haven’t written anything in my blog for the last three years, and that is partly due to the fact that during that time I have been directing a lot of my energies to a postgraduate course, a Master of Science (MSc) degree in Geographic Information Science or Systems (GIS). I have now finished the… Read more »
A new look for my blog
My blog is now over seven years old and it was time for a revamp, so I’ve updated it to the latest version of WordPress and redesigned the theme, which is based on WP-Bootstrap, developed by 320 Press. The design also integrates with the rest of my website, which uses the Drupal Bootstrap theme, so… Read more »

A Zoologist on Baffin Island, 1953
I have been interested in the Canadian island of Baffin Island since ‘Frozen Fire: a Tale of Courage‘ by James Houston was a set text when I went to school. Baffin Island, which straddles the Arctic Circle in the Canadian Arctic Archipelago is in many ways the archetypal ‘Arctic’ location – it has sea ice,… Read more »
Garbh Choire Mòr
For several years now, there has been a secretive and remote location in the Scottish mountains that I have been trying to get to. This location is Garbh Choire Mòr, a corrie at the western end of the larger An Garbh Choire in the Cairngorm mountains, between Braeriach and Cairn Toul, and it is notable… Read more »
I am a software engineer / database administrator / web developer living in Edinburgh, Scotland. In my spare time I like to travel and take photographs (especially of mountains). See my main website here: Eddie's Photo Archive
