#30DayMapChallenge Day 18: Out Of This World
I used several Python libraries, including skyfield, to recreate the current constellation of stars above me in the night sky.

Sentinel-2a rgb satellite image of area around Lochinver in NW Scotland. New tool was using new #gdal application for initial process then #GIMP for colour correction, saturation and sharpness. New discovery that GIMP can save GeoTIFF images. Images show before and after. I think I need to work harder at colour correction - it's too green and still rather dark.
Data downloaded from Copernicus Browser - https://browser.dataspace.copernicus.eu/.
#30dayMapChallenge Day 17: A new tool.
RGB satellite image of area around Lochinver, NW Scotland after colour adjustments in Gimp. Colour correction, saturation and sharpness. Clearer than unprocessed image but I need to practice more.
RGB satellite image of area around Lochinver, NW Scotland. Before processing in Gimp. Very dark and unclear.

#30DayMapChallenge 🗺️ : jours 9 (à la main) et 17 (nouvel outil).
L'Archipel d'Ieu ! 🏝️
Le territoire où dominent les noms de lieux... en "-ieu" ! Entre Forez, Lyonnais, Bugey et Nord-Isère, un motif récurrent, d'origine gallo-romaine, équivalent du "-ac" du Sud-Ouest.

🗺️ Day 13 — #30DayMapChallenge | 10 Minute Map
Today’s theme was all about speed: create a full map in just 10 minutes. ⏱️
I put together a quick Melbourne land-use map, showing how residential areas, parks, industrial zones, and transport corridors shape the city. Even in a fast workflow, the spatial patterns come through so clearly.

It's Day 10 of the #30DayMapChallenge and for the "air" prompt, I decided to look at air quality data before and after Bonfire Night in the UK 🎇

For the "accessibility" prompt on day 7 of the #30DayMapChallenge, I decided to investigate how accessible the default #ggplot2 colours are to people with different types of colour vision deficiency (and for different numbers of colours used). 🎨
TLDR: please choose a different, accessible palette

Day 6 - 'Dimensions' #30DayMapChallenge
A comparison of the dimensions of the Great Pyramid with Edinburgh
It's easier to visualise the size of something when you can compare it to something you see every day :)
