The Reasons Behind the Hexagon Hype — This blog post was originally posted on Anagraph’s website where I currently work. Introduction You have probably seen some cools maps fly by that made used of hexagons instead of other grid systems to represent continuous and discrete data. …

Exposing a far too frequent and erroneous geospatial algorithm My Initial Presentation I presented what I coined the Legend of The Buffer last GIS Day at my alma mater, Sherbrooke University. You can find my presentation on youtube. I removed all algorithmic complexities with a straight-to-the-point article outlining my main ideas. The main…

Not the Shortest Path — Ep. 2 🌎 📡 💾 What is 'Not the Shortest Path'? Welcome to the 3rd episode of Not the Shortest Path. Releasing a new episode every two weeks seems sustainable with my workload. …

Not the Shortest Path — Ep. 1 🌎 📡 💾 What is ‘Not the Shortest Path’? Welcome to the 2nd episode of Not the Shortest Path where we explore the trials and tribulations behind our geospatial applications. We, developers, consistently simplify the stories of how we got to an expected result. There is a tone of…

The Context Behind Legacy Code — Introduction There are entire communities, podcasts, and books dedicated to the practice of mending existing code. There is actually so much content and different opinions that it can be confusing. When I started looking into the best practices behind working with legacy code, all the content I found was either too…

Vertically integrated solutions will overrule generalist solutions in Geospatial — Geospatial is a different kind of beast. The landscape of enthusiasts, companies, and academics is incredibly rich, diverse, and confusing. Hell, just defining the term Geospatial still spurs debate amongst the community (see Matt Forest’s post: Geospatial needs to be defined). Here’s how I usually go about defining geospatial. The…

Exploring the design of a focused geospatial library I have been developing an introduction to geospatial data structures and algorithms. The main roadblock I was facing was building a minimalist library to assist with the introduction. I wanted the introduction to be hyper-focused on learning the principles of geospatial computation…

Applications of the Adapter Design Pattern in Geospatial — Why are design patterns used? The use of design patterns is to apply the design of common solutions to similar problems. They are not precise implementations of code but a template for the context of a given problem. Avoiding repetition is not enough to explain why design patterns exist. The design patterns have the intent…

A Detour in Computational Complexity — Introduction I recently faced a small but interesting problem during a relatively high-pressure situation. Without going into the details, it was in my best interest to efficiently solve the problem. I came out of the situation realizing that the most effective solution was staring me right in the face. However, I…
