#30DayMapChallenge 🗺️ Day 6️⃣: Dimensions

I decided to use time as my dimension and create a simplified animated map showing the Earth’s terminator (the line dividing day and night) around the #Philippines 🇵🇭 at 6 p.m. throughout the year. 🧵 1/3

#30DayMapChallenge 🗺️ Day 5️⃣: Earth

Here’s a minimal isometric relief map of Santorini. I haven’t been to #Greece 🇬🇷 but I definitely want to see Athens, and either Santorini or Mykonos. Maybe I hope that by creating this map I can manifest that trip? 😁

Digital elevation model data is from NASADEM.

#30DayMapChallenge 🗺️ Day 4️⃣: My data

Here is a hexbinned map of the over 1600 #Wikidata items I’ve created that have coordinates. The vast majority of these are items on barangays and historical markers which you may have seen I’ve posted about if you’re following me. 😉

#30DayMapChallenge 🗺️ Day 3️⃣: Polygons

I went with a classic #choropleth map to keep things simple and this one shows the population change of the 201 barangays (kinda like wards) of the city of Pasay in the #Philippines 🇵🇭 between the 2000 and 2024 censuses. 🧵 1/2

#30DayMapChallenge 🗺️ Day 2️⃣: Lines

This map shows all the airports with direct flights from #Singapore’s 🇸🇬 #ChangiAirport (#SIN) rendered on a custom logarithmic azimuthal map. Airports that are served by more airlines, like Jakarta (CGK) and Narita (NRT), are shown more prominently. 🧵 1/3

Third year participating! 🎉

Here’s a map of all the cities and towns in the #Philippines 🇵🇭 that have Spanish names of saints because November 1st is All Saints’ Day. 🧵 1/4

It took me longer than expected but I have finished editing an additional 50 photos meaning I have now completed doing perspective corrections on 450 photos of NHCP historical markers of the #Philippines 🇵🇭! 🎉 I hope to complete 500 by the end of 2025. 1/2

Today, #TimorLeste 🇹🇱 becomes the ASEAN’s 11th member when the 47th summit begins in Kuala Lumpur later. 🎉

To mark this occasion, I created a mock Philippine historical marker for the body owing to the #Philippines being a founding member and the bloc’s importance in modern Philippine history.

One of the current outrageous U.S. news of the moment is the ongoing demolition of the White House East Wing to make way for the construction of Trump’s ostentatious state ballroom.

Anyway, I got curious and was not at all surprised to see that @openstreetmap.bsky.social is already updated. 1/2

I went ahead and created a new image with the correct final character, uploaded it to @wikicommons.bsky.social, and updated almost Wikipedia references to the original wrong image.

The street names in this part of Queens, New York City, seems deliberately confusing. 🤨🗺 #NYC #NewYorkCity

With the impending arrival of Typhoon #OpongPH and the recent protests against corruption in government-funded flood control projects, the recent release of the 2025 World Risk Report, with its topical focus on flooding, is very timely. 1/2

Thank you, #NDRRMC¹ for the delayed earthquake² SMS alarm. I did feel it but it was so subtle that I thought it was just my heart suddenly palpitating.

I finished watching this Netflix documentary about the 2003 Antwerp diamond heist and while the film itself is your typical informative docu, I am again peeved that @openstreetmap.bsky.social was used without any credit whatsoever. 😠

Now added to the OSM Wiki: wiki.openstreetmap.org/wiki/Films

Here's an attempt at making a somewhat artistic photo of a mundane object by making it black and white and upping the contrast and only using the phone's built-in editing tools. #photography #BlackAndWhite

And here’s a screenshot of @heigit.org’s Ohsome Stats tool showing the near real-time graph of the number of edits with the #OSM21 hashtag.
