I used a combination of OSM data and data from data.grandlyon.fr for digital terrain model and a digital surface model to create the analyses. It was super interesting, because with just a little investment of time, and publicly available resources, I was able to create really neat looking reports on all kinds of solar availability metrics like sky view factor, sun hours, and sun-path animations.</p> https://ianvangiesen.com/blog/my-new-post/ Thu, 20 Aug 2026 00:00:00 +0000 https://ianvangiesen.com/blog/my-new-post/ <p>The post is written here!</p> https://ianvangiesen.com/blog/just-wheeling-around/ Thu, 02 Jul 2026 00:00:00 +0000 https://ianvangiesen.com/blog/just-wheeling-around/ <p>Before I finally bought a bike that fits my size, I made the mistake (read: multiple mistakes) while trying to fix a bike that I was luckily loaned at the beginning of my stay in France. I suppose the upside of my failed repairs, is that I won&rsquo;t make the same mistakes again! First issue, was that I bought a single wall wheel instead of a double wall wheel. This elicited a groan from the bike repair I visited to replace the old rim-tape.</p> https://ianvangiesen.com/blog/first-post/ Sat, 07 Feb 2026 00:00:00 +0000 https://ianvangiesen.com/blog/first-post/ <p>hello world, first post!</p> https://ianvangiesen.com/blog/ian-ali-spaceship/ Thu, 29 Aug 2024 00:00:00 +0000 https://ianvangiesen.com/blog/ian-ali-spaceship/ <p>Ian and Ali are in the spaceship.</p>
