Let's go for the #30DayMapChallenge 2022!
I'll push all my entries in this thread. I'll do my best to do the full 30 days! But it's pretty intense, so maybe some skips or republishing of past projects… We'll see!
Here is the list of themes by @tjukanov

#30DayMapChallenge - 1 - Points
Viewpoints in metropolitan France
Source: OpenStreetMap
Tool: QGIS
Show threadBenjaminNov 1, 2022

Starting small and abstract. I work everyday on a big spatial analysis platform with intricate datasets, I guess I craved some simplicity :)

Anyway, Grenoble seems to be the French capital of viewpoints. Well played Alsace too!

Love the exquisite palettes built into QGIS!

I spent my last summer holidays there. The highlight was a long hike to the plateau, first climbing this very steep cliff.
Stunning view from the top!

Other worthy candidates for this kind of geometrical map: Palmanova (IT), Grammichele (IT), Neuf-Brisach (FR) and probably a lof of crazy US city plans.

Difficult theme today… No way I could make something about the war as good and respectful as the maps from some newspaper cartographers.
I realized I wasn't even familiar with what the country looks like physically. So, a topo map, even if it looks like an easy way out.
Show threadBenjaminNov 5, 2022
I don't feel very confortable with the coloring either. As the scale is showing I had to "cheat" to balance the colors, but that is ok.
It just made me think I would never do a blue-white-red map of France, and not just because it would look ugly :D

The most complicated part was probably getting a crisp and flat enough photo of the map.
I bought it in a bookshop in Hay-on-Wye, among other marvels of the same era. If I had a pub, it would be a carto pub and they would be on the walls.

I know it's a rather bad map (hard to read, not enough color contrast, not the most efficient way to present the information), but with the theme I couldn't resist making something with honeycombs.

My favorite one: that one in Portree, on the Isle of Skye, where I ate a delicious fish and chips under the snow while looking at an otter swimming in the harbour. Just had to fight strong with the seagulls and hooded crows :D

Aaaand this map marks the middle of the month, and I've made it until now \o/
We'll see for the second half, as there are more themes where I have no idea at all yet.

Engraved map of the Aran Islands.

I think I entered the 30DayMapChallenge mainly for this reason: after 5 years of intaglio practice, stop procrastinating and finally try to make a map.

#30DayMapChallenge - 19 - Globe.
Chalkboard globe with hand-drawn oceans and landmasses.

Some years ago I bought cheap deco globes and covered them with blackboard paint. I offered most and kept one and this is still one of my favorite objects.
I erased and redrew it for the challenge.

Alternative ways of printing my engraved map of Aran Islands from day 17.
First with brayer and black ink only, like relief printing. Then inked in the normal intaglio way + brayer with translucent blue ink.

#30DayMapChallenge Congratulations to every one who created maps during this month! So many great cartographers discovered!

Here is my own month summed up. My "Recent projects" view in QGIS looks nice too :)
