Day 10 of the #30DayMapChallenge - Air - Map of the world's airports and airways.
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 8 of the #30DayMapChallenge Urban - Roads of the world. Couldn't think of anything more urban than roads.

Capitalism vs communism eh 😉
Day 7 of the #30DayMapChallenge - Accessibility - "Visualize travel time, barriers....." - Here is a map showing nighttime lights in the Korean Peninsula. The border between North and South is visible from space.

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 five of the #30DayMapChallenge - Earth. Soil moisture. Data comes from the TerraClimate project. I love this colourmap.

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.
Do I just like making pretty pictures? Yes

Aridity of Oceania. Aridity is usually expressed as a generalized function of precipitation, temperature and reference evapo-transpiration. Higher values represent more humid conditions and lower values represent higher aridity.

Few people realise the scale of the Himalayas because static maps are a bad way to convey topography. Fortunately, we can use interactive maps to explore topography. Here is an example using Pyvista.

Here is an old favourite. Shipping lanes. This time drawn using the Spilhaus projection, which centers the map on Antartica and presents the worlds oceans as one continuous body. Athelstan F. Spilhaus, a South African-American geophysicist and oceanographer in 1942

I have combined two datasets for fun. Here are the world's shipping lanes (red) and the worlds flight paths (white) on the same map.

Expermineting with different datasets. Plotting a topography map, with contour lines on top creates a really cool hillshading effect. Couple that with rivers and you are getting close to a OS map, all in Python
