New Term: Neil Brown Ocean Sensors Inc. (NBOSI) ยท Issue #8 ยท nvs-vocabs/L35 Hi vocab team, I'd like to request Neil Brown Ocean Sensors Inc. (NBOSI) be added to the L35 vocab. They make CTDs, inlcuding a couple on our sailbouys https://www.nbosi.com/ From their linkedin ov...

Submitting new terms to the BODC vocabulary server feels like the one kid asking for more homework. Does anyone actually use these? I feel like controlled vocabularies are a nebulously good idea, but find it hard to articulate a real life use case.

ogr2ogr : Converting KML to GeoJson I have a requirement to convert .KML file to GeoJSON or JSON. Can you please recommend open source command line tools on GNU/Linux(2.6.32-358.14.1.el6.x86_64)? I have installed gdal, when I run..

probably not gonna run on valtown, but I use the omnipotent gdal for all my geoprocessing needs. In this case `ogr2ogr -f GeoJSON out.json in.kml`

I like geojson. Plays much better with leaflet etc.

What you think Argo float users want:

- โœ… Greater depth rating
- โœ… More BGC sensors
- โœ… Higher sampling rate

What Argo float users want:

- โœ… A smaller hurtbox

A complete stranger just dropped into an Issue on a package I created. He offered a far superior and more elegant solution to a user's problem than I had given. Open source is the best!

Despite the wikipedia horror stories, none of my edits have been reverted!

Two more experienced editors have offered me help/mentorship, and a wikipedian with the requisite power actioned my page rename request.

No regrets :)

Inspired by @molly.wiki I finally signed up to wikipedia to correct an out-of-date oceanographic research vessel's page.

It amazes me that one of the greatest repositories of human knowledge is an open collaborative project.

Last Monday I gave myself an hour to spin up a demo meteorological data display/download app with #python and @streamlit.bsky.social. Pretty happy with it! aws-demo.streamlit.app

This Monday I took an hour to realise I was debugging the wrong server ๐Ÿซ
