#Projections for #30DayMapChallenege

An animation of 24 hours (from midnight at UTC+00:00) on Earth today, in four different projections: Left to right, top to bottom: #Orthographic, #Stereographic, Interrupted Goode Homolosine and #Spilhaus.

Plotted with #cartopy 's Nightshade function (repeated calls to get the different twilight zones) and #matplotlib at 15 minute time steps and then stacked together in #gimp

Background image is cartopy's `stock_img()`.

re-used some code I threw together recently to make a thing for changing my desktop background: https://tlohde.com/blog/2025/10/because-i-cant-afford-a-geochron/

day 24: #only_circular_shapes

Encircled Iceland Incircles.

The biggest circle that fits inside of Iceland (an "incircle") (in UTM), and the next biggest that doesn't overlap the first, and the next biggest and so on...

https://en.wikipedia.org/wiki/Incircle_and_excircles

method implemented similar to that of Garcia-Castellanos & Lombardo 2008 https://doi.org/10.1080/14702540801897809

colors are that of the Icelandic flag

#30DayMapChallenge

Anyone knows how to plot lake shorelines with #cartopy It is easy to get the (ocean) coastlines, but I don't get it to plot the shorelines of lakes.

James Sturman from NIWA presenting on the Development and Implementation of Historical and Current Climate Mapping for Vanuatu.

Important to have good quality weather data distributed spatially and temporally, and lots of open source software (e.g. @geopandas, @gdal, #xarray, #cartopy) to do the processing and final map creation!

@EL_Uatu @ruthpozuelo if you know the lat/lon of each of you crime "cell", and the projection information to go from x/y to lat/lon you can use #pyresample (from the #pytroll ecosystem).

That's what I use for plotting satelitte and weather data. But #cartopy or #basemap can probably do the transform for you if the ony thing you want is plotting.

#ICYMI

Last night, @ruthpozuelo and I found out that #Basemap (the legacy map plotting module of #python) was not dead after all, and that a small team of developers are taking care of it.

This can be of interest for those of you that have not fully transitioned to #Cartopy yet (I have).
