π€π©πΌβπ« Today we presented FOSS4G Observatory at #GeoEarth Conference, which marked 125 years of geography education at University of Bucharest (Romania) ππ .
Our poster highlighted the platformβs role as a digital infrastructure for open-source geospatial projects π βοΈ and as an interactive learning environment supporting autonomous and discovery-based learning π»ππβοΈ

as always you can find all the past #geoweirdness and #geoeducation threads linked over on the blog:

Enjoy!
5/ #OpenStreetMap is so big now (>5 million edits/day) and the community behind it is truly global πππ
It is now used in so many different places and ways that it can be hard to keep up with all the things that are happening. We wrote a #geoeducation thread about staying up to date on OpenStreetMap
After a week off to enjoy the summer this week's #geoeducation thread again focuses on OpenStreetMap The OpenStreetMap community is massive (and growing) πͺ, global π, and very dynamic πΊπ! The OSM database has millions of edits per day. Lots of things are happening all the time. But ... that can also be a bit overwhelming. How do we stay aware of what's happening? #OpenStreetMap 1/n

2/ Before we go full #geoweirdness , a bit of #geoeducation
Time zone information is tracked by the "tz" database, a fascinating, open-source project worth learning about!
https://en.wikipedia.org/wiki/Tz_database
Most countries have simple time zones, generally based on the sun's position relative to the region's positions on the Earth's surface. However, time zones also involves political and historical factors, and thus they don't always correspond to the longitudinal lines on the globe.
1/ Time for this week's geo thread.
We have some fun #geoweirdness planned for the coming weeks, but this week we're back to #geoeducation
Today's topic is something we often see people get confused about: browser geolocation.
What is it, and how is it different than geocoding?
9/ Wrapping up - browser location is an interesting tool that can be used to improve the user's web application experience.
But ... it requires user permission, and even if that permission is granted it can be inaccurate or misleading.
π©βπ Want to learn more? Here's the official W3C geolocation spec: https://w3c.github.io/geolocation-api/
7/ We have a guide to this whole process of browser geolocation to geocoding with example javascript (where the code screenshots above came from)
https://opencagedata.com/guides/how-to-determine-user-location-via-browser-geolocation
8/ Want to see browser geolocation in action?
Give it a go on this OpenLayers tutorial:
https://openlayers.org/en/latest/examples/geolocation.html
But make sure you haven't disabled geolocation in your browser settings. Some browsers helpfully show this in the nav bar.
Please note also that if browser location relies on IP geolocation it can be misled by VPNs.
10/ Thanks for reading (and sharing) this week's #geoeducation ππ§βπthread.

In this week's thread we take a little break from #geoweirdness to switch to #geoeducation ππ§βπ Today we clarify an oft confused and conflated topic that we get asked about a lot: the difference between geocoding and IP geolocation 1/n
