Given that #OvertureMaps has now released their first alpha version of their data, I'm now waiting for someone to create an online tool to either display them on a slippy map or additionally compare them with #OpenStreetMap data. 🤞

(I actually am interested in building such a tool for my country but alas I don't have the luxury of time or resources.)

Feeling bemused.

Despite hiding my birthday on Facebook just so that I can avoid the deluge of online greetings (I'm kinda anti-social that way 😝), the two sets of friends that I met up here in Singapore still remembered! 🥰

Can I ask a favor from my followers? Please do the following steps and reply back with the results:

  1. Go to this Image page on Commons: https://commons.wikimedia.org/wiki/File:San_Isidro_Town_Plaza_(Nueva_Ecija)_21.jpg

  2. On the line immediately below the image, click on either the “180 × 240 pixels” or “360 × 480 pixels” link, then observe the resulting image

  3. Next, click on either the “1,536 × 2,048 pixels” or “3,888 × 5,184 pixels” link, then observe the resulting image

  4. Do the images in step 2 and 3 look the same (just different sizes)?

#30DayMapChallenge 🗺️ Day 5️⃣: Analog map

OK, this was way more fun than I expected! 😝

I decided to try and recreate the shapes of 12 countries using the 4 pieces of the classic T puzzle: https://en.wikipedia.org/wiki/T_puzzle

See if you can identify which countries are which! This is a thread of 3 toots each with 4 countries.

Spoiler: Don't read other people's replies!

(Sadly, I had to omit the alt text for these photos for obvious reasons.)

Edit: Added 4 more countries! 🎉

Ok. I’ll try to do something that I’ve never done before here on the Fediverse... do a semi-live reaction thread of watching the Season 2 finale of .

So similar to S1E7’s and S2E7’s cold opens showing events from 20 years ago, we also get finale cold opens from 3000 years ago.

I can’t get enough of Alexander Karim as Lews Therin and we see him with 7 other companions sealing Ishamael at the Eye. Also, Sammael is namedropped!

Day 0 of is done!

The massive 6-foot-tall cardboard sculpture of the Wikipedia 'W' logo is pretty nifty. And the plenary hall is massive! 😮 I will be presenting here on Thursday and I'm already intimidated. 😱

Today marks the 10th anniversary of the landfall of 🌀, also known as , in the 🇵🇭. This devastating event had a lasting impact in my country and is still the deadliest typhoon in the 21st century having killed over 6300 people.

For the Philippines community in particular, the typhoon radically transformed what it means to volunteer our time, effort, and resources to map and provide freely accessible geographic data.

It’s a good thing Netflix recently added Dune: Part One to their library (at least in my region) so that I could rewatch it before seeing Part Two in the cinema! 🤩

If you see the following video (it’s restricted to certain regions presumably where HBO Max isn’t available), then you will get to eventually see the whole show on YouTube and not just the main story like before. 🤩

Did you know that there is a 1:1 scale replica of the world-famous Scramble intersection that can be rented by TV and film productions located 80 km northwest of Tokyo in the city of ? The real intersection is so busy that nobody can close it down for controlled filming.

This set was notably used in the hit Japanese TV series Alice in Borderland.

I’ve been watching a few travel vlog videos on YouTube and because of my #OpenStreetMap compulsive behavior, I’ve been using these videos as street-level imagery sources to update POIs on the map. 😅

Based on this figure from this new academic paper, it would seem that #Manila, #Philippines is the most populous well-mapped (> 80% "complete") city in the world in #OpenStreetMap in terms of buildings. And we did it without relying on imports!

🗺️ Day 7️⃣:

Decided to do something “simple” for today. Here is a map of all ferry routes ⛴️ in the 🇵🇭 that have been mapped in . Data has been extracted via (data licensed under ODbL 1.0) and rendered via .

Since the Philippines is an archipelago, ferries and boats are important means of transportation especially since the thousands of small islands are too small to host airstrips.

I wonder if there should should also be a next year in November? Basically try to map something new or improve an existing object based on a daily theme in .

So for example, Day 8 could be “Roads”, and you could map a new road or add a surface=* tag or name:etymology=* tag to an existing road.

It would be something fun to do and could help folks achieve the 42 days needed to qualify for free membership to the OSM Foundation (if they want to join).

Data modeling is hard!

The first photo, uploaded to , is of a painting depicting a Philippines Historical Committee marker (shown in the second photo) that commemorates a public square that is named after a doctor.

The doctor, the plaza, and the marker all have items:

Olivia Salamanca: https://www.wikidata.org/wiki/Q37948604

Plaza Olivia Salamanca: https://www.wikidata.org/wiki/Q37949216

Plaza Olivia Salamanca historical marker: https://www.wikidata.org/wiki/Q37948341

🧵 1/2

Small red-granite-clad obelisk bearing a historical marker with the following inscription: Plaza Olivia Salamanca In memory of Olivia Salamanca, M.D., pioneer woman physician of the Philippines. Born in San Roque, Cavite on 1 July 1889; appointed government scholar in 1905; studied in Drexel Institute, Philadelphia. Died on 11 July 1913. A devoted and competent practitioner, she was a credit to the medical profession and an inspiration to her fellow women.

#30DayMapChallenge 🗺️ Day 4️⃣: A bad map

Here’s a map of all 4400 #Catholic churches ✝️⛪ in the #Philippines 🇵🇭 that are currently mapped in #OpenStreetMap (licensed ODbL 1.0).

Data extracted via #OverpassTurbo and plotted using geojson.io to add some styling.

(The map is so bad that I got the “This page is slowing down Firefox. To speed up your browser, stop this page.” message. This is why you use marker clustering, or a GIS tool more suited to the job such as #QGIS or something like @felt.)

🗺️ Day 8️⃣: 🌍

I decided to try something new and create my very first map! The two variables I’ve mapped for 52 African countries are the 2023 scores by and the 2022 by the UN Development Programme.

Unfortunately São Tomé and Príncipe didn’t have a WPFI score while there’s no HDI for Somalia. Of course Western Sahara had no data too.

For today’s theme, here are the locations with photos of all known and extant (aka commemorative plaques) found in Europe that were created by the National Historical Commission of the (). It turns out that these are all related to our national hero José Rizal since he traveled extensively in Europe.

While doing some editing in #OpenStreetMap, I stumbled onto this dramatic transformation at Domoroy Point in Barangay Matayum, Cataingan, Masbate, #Philippines 🇵🇭. In a bid to boost tourism, the local government created the huge man-made Matayum Lagoon.

You can see the transformation by switching to different aerial imagery layers. Mapbox at the top shows the area before the lagoon was created, the middle from Bing with the initial excavation, and the bottom from Esri with the finished lagoon.

Today is the 125th anniversary of the start of the Philippine–American War, which is the ‘ biggest conflict in the period between the Spanish–American War and World War I. The Americans‘ victory by 1902 cemented the U.S.‘ reputation as an imperial power with colonies across the Pacific from Manila to San Juan, Puerto Rico.

What I find really sad is that most Americans don’t even know about this war, which is glossed over in American history school books.
