#30DayMapChallenge: Day30: The Final Map

Here is the second map I forgot to post. I realised I hadn't done a bivariate map yet so here is one showing the average broadband speed and percentage of people who work mainly from home, in LSOAs in Yorkshire and Humberside.

#30DayMapChallenge: Day29: Overture Data

Just realised that despite making them in time, I forgot to post my last two days of the challenge here. Whoops. Anyway, here is a map of the location of castles in the UK. Better late than never.

#30DayMapChallenge Day 28: The Blue Planet

Known shipwreck locations across the world. I have been looking for an excuse to shoehorn this dataset into one of the daily theme and finally found a way.

David Leather @davidleather.bsky.social · Nov 27

Yes, same goes for me unfortunately! Playing tennis there has given me a good excuse to visit more often though.

#30DayMapChallenge Day 27: Micromapping

I will reiterate again that I love map in a circle so here is another one. A map of Low Bradfield village in Sheffield where I have had many a family walk and more recently attempted to take up tennis.

#30DayMapChallenge Day26: Map Projections

Wasn't particularly inspired by todays theme but after trying different projections at random, I somehow ended up with whatever this is, maybe some sort of world cube template? Thankfully I will never be able to recreate it.

#30DayMapChallenge Day 24: Circular Shapes

Had a go at creating a Dorling Cartogram in @tableau based on world pop densities. Turned out OK other than the USA and Canada floating out to sea. Technique was learned from this @professorkao.bsky.social tutorial: typefully.com/professorkao...

Ha! The main this I learned from making this map is that ChatGPT doesn’t know everything….at least not yet anyway.

#30DayMapChallenge Day23: Memory

I tried to draw the centre of the village where I grew from memory then compared it to the real thing. Not a bad effort considering I have only been back once in the last 20 years or so.

#30DayMapChallenge: Day 22: Two Colours

A simple map of Sheffield city with a nice pink/grey combo, again using OSM. Not much else to say about it other than that.

#30DayMapChallenge Day20: #OpenStreetMap

OSM meets WSM - I love a map in a circle so will take any excuse to produce one. This time I chose Weston-super-Mare as I grew up near the town. The colour palette is inspired by old vintage seaside posters.

I know there must be lots missed from the list, I wish I had time to research them all!

David Leather @davidleather.bsky.social · Nov 20

Reposting this as I forgot to include the map first time round!

#30DayMapChallenge Day19: Typography

I asked ChatGPT to produce a list of fonts named after places and then I mapped the results. Resisting the temptation label each place in its own font is one of the hardest things I have ever had to do, so they are all in Berlin Sans instead.

#30DayMapChallenge Day 18: 3D

Catching up after a few days off mapping with my annual attempt to get my head around Blender. This time I persisted with it until the bitter end with this map of Yorkshire and Humberside using this rather helpful tutorial:

#30DayMapChallenge Day 17: Collaborative Map

I don't get the change to do many collaborative GIS projects, sadly, but I did recently work with colleagues Amy Grace and Steve Parkes to visualise South Yorkshire's consumption distribution for an journal article:

#30DayMapChallenge Day15: My Data

Expanding on my effort from Day 5 this shows a trip we took to California, but expanded to show the whole journey. Largely inspired by a lack of time and imagination but it fits the brief.

#30DayMapChallenge Day 14: A World Map

This is an update of something I did a while ago - A map of power plants across the world by primary fuel type. This time using Tableau Public.

#30DayMapChallenge Day13: A New Tool

Playing catch up after a couple of day off mapping. I have been meaning to get round to using R for ages so this was a good excuse. I made this basic pop density map of California by religiously following this helpful tutorial: eriqande.github.io/rep-res-eeb-...

#30DayMapChallenge Day11: Arctic

About 10 years ago my Grandad was posthumously given The Arctic Star for serving as a navy signalman in the Arctic Convoys in WW2 on the HMS Mackay.

I couldn't find the route of his convoy (PQ18) but this is an approximation, based on info from naval-history.net.

#30DayMapChallenge Day 10: Pen & Paper.

A highly detailed map of my average commute to the office. The biggest challenge was finding a working pen.
