#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.
Map of the island group of Santorini shown in an oblique isometric view such that the sea level is a very light tan color with the islands in an aqua color ranging from nearly transparent at sea level to very dark cyan at the highest point. The map is titled with a large text “SANTORINI” with the Greek “ΣΑΝΤΟΡΊΝΗ” above it in a smaller font size and the coordinates 36° 24′ 13″ N ▪ 25° 23′ 45″ E below in an even smaller font size.

#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

Choropleth map of the 201 barangays (wards) of the city of Pasay in the Philippines showing the population change between the 2000 and 2024 censuses. The more positive the population change, the more dark blue the barangay gets while the more negative, the more dark red.

#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

#avgeek
Light-grayscale map titled “Airports with direct flights from Singapore’s Changi Airport”. The map is circular using an azimuthal projection centered on Singapore, labeled with a red dot with the IATA code of SIN, and with distances marked in a roughly logarithmic scale in intervals of 1000 nautical miles. Lines connect Singapore with 162 other airports labeled with their IATA codes. Most lines and airports are dark gray but some like Jakarta (CGK), Denpasar (DPS), and Narita (NRT) are redder and with a larger font size indicating importance.

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.
Photo of a mock NHCP historical marker with the following text: Samahan ng mga Bansa sa Timog-Silangang Asya (ASEAN) Bunga ng mga aral mula sa mga naunang samahan tulad ng Southeast Asia Treaty Organization (1954), Association of Southeast Asia (1961), at Maphilindo (1963), nagkita ang mga ministro ng ugnayang panlabas ng Pilipinas, Indonesya, Malaysia, Singapore, at Thailand noong 8 Agosto 1967 at nilagdaan ang Deklarasyong Bangkok na nagtatag sa Samahan ng mga Bansa sa Timog-Silangang Asya (ASEAN). Ginanap ang unang pagtitipon ng mga pinuno ng mga kasaping bansa sa Bali, Indonesya, Pebrero 1976. Lumawak ang samahan nang sumali ang Brunei (1984), Vietnam (1995), Laos at Myanmar (1997), Cambodia (1999), at Timor-Leste (2025).

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

Apropos of nothing, here is @xkcd.com 1357.
A six-panel comic strip showing a stick figure named Cueball. 1. Cueball: Public Service Announcement: The Right to Free Speech means the government can’t arrest you for what you say. 2. Cueball: It doesn’t mean that anyone else has to listen to your bullshit, or host you while you share it. 3. Cueball: The 1st Amendment doesn’t shield you from criticism or consequences. 4. Cueball: If you’re yelled at, boycotted, have your show canceled, or get banned from an Internet community, your free speech rights aren’t being violated. 5. Cueball: It’s just that the people listening think you're an asshole, 6. [A picture of a partially open door is displayed.] Cueball: And they’re showing you the door.

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
Frame from the 2025 documentary Stolen: Heist of the Century showing a desaturated basemap of central Antwerp, Belgium, centered around the diamond district with a red pin at the center labeled “Diamond Center” and with an accompanying photo of the building’s faade. A subtitle caption says, “under the cell tower of Diamond Center.”
