#30DayMapChallenge Day 29: Raster
#LiDAR DSMs often leave nodata voids at water bodies, breaking shadow modeling. For Rotterdam, I used the 0.5 m AHN4 DSM and filled gaps with my #QGIS script from the Resources Hub 👉 hub.qgis.org/scripts/4 (install via QGIS Hub plugin).

Another go at it from a couple of years back. A little too much "just slap hill shade on it" but I still like it.

In my ever ongoing project to create a nice-looking map of the two hills near where I live, this is where we're at today. Needs more work, but I think it's kind of cute, especially given the very limited pre/post processing. (Inspiration from this lovely map: […]

It's becoming increasingly clear to me that Reflect Orbital's fucking stupid giant mirror satellite, with absolutely NOTHING useful to offer, which will cause countless safety issues, ecological disasters, and destroy the night sky, is going to launch.

I keep finding vapes chucked on the ground as I cycle around. I pick them up because they're toxic if left to degrade.

Strava, struggling hard to show as misleading graphs as possible. This 4:36 min/km run was much, much slower than the last 4:36 min/km run (the trend is somewhere in between, about 4:36 min/km). #running

If you can read Swedish, this mail has all the telltale signs of a phishing email, but no, it's a legit email regarding a package I actually ordered.

Yesterday was the first time I arranged an #orienteering training without using Purple Pen or OCAD, instead all courses set in the browser using my own O-Scout software. Still far from feature complete, but actually sort of useful now.

Yet another attempt to use ChatGPT. Every time I end up fighting it over stupid things it more or less makes up. Really curious what the people claiming to be productive do with it.
(What really happened was that I tripped on Python's GIL, which took me a bit too long to figure out.)
