Time for this week's geothread, a dose of #geoeducation rather than #geoweirdness
Today we thought we'd cover a common geocoding use case: extracting the coordinates from images ๐ธ and geocoding the location the image was taken.

The question will be posted at 18:00 Berlin time / 5pm UK / 12 noon US east coast time. Rules, prizes, past questions are all over on the blog: https://blog.opencagedata.com/post/geotrivia-july-2023 ๐ โ๏ธ The end of the month is almost here, which means ... #fridaygeotrivia - our geo trivia game played here on mastodon on the final Friday of the month.

Full details on the blog: https://blog.opencagedata.com/post/geotrivia-july-2023 As always you can/should practice on past questions to get warmed up for #fridaygeotrivia https://blog.opencagedata.com/tagged/fridaygeotrivia See you Friday! This week in #geoweirdness rather than focusing on a specific county or territory we thought we'd post a bit about confusing places in general. These come up a lot in geocoding. What exactly do we mean? People often have a perception of a place that doesnโt match the true geographic reality. Hereโs a basic example, saying "the United States" ๐บ๐ธ but meaning only the contiguous US 1/n 2/ One of the best โconfusingโ countries is France ๐ซ๐ท. Many peopleโs perception of France is just European or โMetropolitanโ France. https://en.wikipedia.org/wiki/Metropolitan_France But France is much more than that, as covered in our thread back in February: https://en.osm.town/@opencage/109930044904649272 Most of the questions we get about geocoding are related to land, but of course most of the world is covered by water ๐๐๐โต๐ This week in #geoweirdness let's consider the world's oceans 1/n 2/ There are some fun water based locations. For example "Point Nemo" (-48.876667, -123.393333) The point on Earth farthest from land In this week's #geoweirdness thread we leave Europe and turn our attention southward to ... Australia ๐ฆ๐บ So what's geoweird about Australia? 1/n 2/ Well first, Australia ๐ฆ๐บ is very big, twice the size of the EU ๐ช๐บ , but itโs much bigger than you probably think, with many external islands. Just like last week's country Norway ๐ณ๐ด, Australia claims territory in Antarctica. |
2/ When you take a picture by default most digital cameras record all sort of meta info, and store that data in the resulting image file.
Things like type of camera, exposure time, etc.
This is known as "EXIF data". Exif stands for "Exchangeable image file format"

@opencage This could be practical for OSIRTโopen source investigative research techniques (fka OSINT) !!
