Day 21 of the #30DayMapChallenge - Icons - Use icons to highlight points of interest. Here are lighthouses of the Caribbean and Gulf of America. I used a few tricks to make the points look like they are shining out to sea.

Day 19 of the #30DayMapChallenge - Projections. Here are maps showing tropical storms using a number of different projections. We have the South Polar Stereo, the Robinson, the Lambert Conformal and finally I have included a shipping lanes map using the infamous Spilhaus projection.

Day 18 of the #30DayMapChallenge - Out of this World. Here is a topographical map of Mars. I have added some hill shading and used a colourmap that simulates an ocean, proportionally equal in size to Earths.

Day 17 of the #30DayMapChallenge - New tool. It has been on my radar for a while so I tried out datashader to visualise population density. These maps usually take minutes to render but with datashader it takes seconds.

Day 16 of the #30DayMapChallenge - Cell - Here is a map of Cell tower density in Europe. Clearly this is just a population density map but gotta follow the theme.

Day 13 of the #30DayMapChallenge — 10-minute map.
Once I’ve made a particular type of map once, I can usually recreate it in about 10 minutes. This one’s a bivariate map — the style that probably took me the longest to learn the first time around. Rainfall vs Temperature in South America

Day 12 of the #30DayMapChallenge - Map from 2125 - I think Northern Ireland and the Republic of Ireland could merge into a new country. So here is a topography map.

Day 11 of the #30DayMapChallenge - Minimal - Population density of Egypt. This was always my preferred style but recently I caved to academics who wanted labels and keys 🤮. Glad to get back to basics.

Day 9 of the #30DayMapChallenge - Analog. Create your map using traditional methods. Obviously I am not going to stick to this. Frankly nothing is more traditional that Python so here is another map made with Python. Roads of the Roman Empire.

Day 6 of the #30DayMapChallenge - Dimensions. A thread of a few maps that cross into the three dimensional world. Here is a 3D representation of the topography and bathymetry around Gibralta.

Day four of the #30DayMapChallenge - Data challenge: My Data. I made some historical geojsons of the Roman and Mongol empires. Accuracy is vaguely correct but the Mongol Empire does look a bit like a bear.

Day three of the #30DayMapChallenge - Polygons. This map shows the earths tectonic plates. I have overlayed all of the earthquakes with a magnitude greater than 4.0 over the last 20 years, coloured according to their magnitude (blue (smallest) - red (largest).

Day one of the #30DayMapChallenge - Points. These maps show lighthouses of the British Isles, the Aegean Sea and Italy. I have tried to simulate how they would shine and cast light out to sea.

Soil moisture. Data comes from the TerraClimate project.
Is my choice of colourmap appropriate? No.
Do I care? No.
