I meant I was following the tutorial of the PyGMT package that works with data for Mars. I experimented with the colors. I should go to higher resolution data soon for this as the map is kind of pixelated.

El día de hoy el #30DayMapChallenge es para probar alguna técnica o herramienta que no hemos usado. Ya antes había intentado hacer un globo terráqueo con un patrón que saqué de internet. Hoy me animé a usar Excel de una forma que no había explorado: para crear patrones.

#30DayMapChallenge - day 17 - new tool - RiverDem in Python (default settings) - A bit experimental and still work in progress. I used the entire DEM file obtained from Copernicus Global Digital Elevation Models and the Python PIL package to finish the image.

And I did a complete "dump" of all the features in OSM. Need to figure out what is what now and refine this map a bit 😀

I always wanted to make something that looked like a poster. I know this is done by many people these type of maps (but not specifically for Oostende - my birthplace) so this was an opportunity to try this out in QGIS.
