PostGIS Day 2025 Talk Now Live - Working with Geospatial Embeddings | Geobase Watch our talk from PostGIS Day 2025 on how we built geospatial embeddings directly into Geobase.app by extending PostGIS with PGVector, enabling semantic search and similarity queries over maps, rast...

geobase.app/blog/postgis... my talk from PostGIS day is now online - I talked about vector embeddings and geospatial data in PostgreSQL. So many of my favorite tech in one talk!

This is a completely made up point cloud but its for a real place!

We have been testing generative models to create 3d meshes ... this is based on Skyfall-GS I'll write a longer post on this on our @geobase.bsky.social blog soon, though still a long way to go for applications but impressive.

congrats on the book Bart. Is the English translation expected at all?

Adding deckgl support to geoai.js github.com/decision-lab...
thanks to Felix Palmer for the suggestion to help get this going - minimal demo: codepen.io/sabm/full/VY...

Recently had some fun micromapping Pillar Falls in Idaho's Snake River Canyon. Featuring dramatic basalt pillars, this falls runs over exposed bedrock much of the year (intermittent=yes in OpenStreetMap terms). This makes for a popular local hangout spot and an interesting place to map

I just released geoai.js an open source toolkit for doing GeoAI in the web using webGPU

Just a few steps with the new Geobase blueprint, and I've got detailed shipping data up and running. Even surprised myself with the speed! awesome narration by @tim_waters
code at github.com/decision-lab... #gischat #javascript #reactjs #geodev

new feature!

this was fun to make - took me 1 hour to go from idea to working prototype - thanks to geobase's APIs and ecosystem!

I've been playing around with #ecmwf #weatherforecast model called AIFS. Deployed a demo inference app it was super smooth and works reasonably fast on a small GPU well done to @ecmwf.int form making the model available! 🇪🇺

Geobase now supports satellite and drone data! YouTube video by geobase

youtu.be/-EzU1hOuXa4
Geobase now supports satellite data via STAC protocol or Cloud Optimised GeoTiffs. now you can build app in the domain of agri-tech, smart cities, urban planning and much more without leaving your favorite javascript dev stack, next.js, vue.js or even vanillajs #gischat

Today we are really excited to announce support for multi-band Raster Tiles and Cloud Optimised Geotiffs (COGs) in Geobase! (only in private beta ATM hit us up if you want early access)

Geobase Blueprint: Shareable Maps (Next.js) YouTube video by geobase

🎁 If anyone's thinking of starting their journey to becoming a GIS/Geo dev & like to learn by doing, then this holiday season, try to build a real-time sharable maps app

Video of final app www.youtube.com/watch?v=vcWF...

Start building! 💻 #gischat #js

I finally gave in to my 5-year-old niece… she’s now racing on a Rainbow Road! 🌈🗺️✨ Built her this racing game using real #OpenStreetMap data with geobase.app 🚀 #GISchat #MapMagic

When you spend 20 minutes explaining vector tiles to your 5-year-old niece and she hits you with: 'But can it be a rainbow tho?' 🌈📍 #gischat #geo #cartography

yea, you could have gotten away with saying my 19 year old niece who's starting her giscience degree at RMIT :D

who's doing the voice over Matt?

So we are adding 3D geo vizualisation blueprints now ... signup to the waiting list and start building 3D geoviz like a boss with 👉 geobase.app

FACT: Geospatial developers earn more monies than regular devs [1]

FACT: geobase.app makes becoming a geospatial developer, dead easy... go from data to vector tiles in one second in geobase [2]

👉 geobase.app in action!

[1] made up that fact 🤷
[2] true fact 😊

#gischat #javascript #fullstack

We just ran a super resolution generative model on top of imagery by ESA over Riyadh. One can use it to get change detection over old images and new images and see things that you can’t see the lower resolution. It’s a very cool, though must be used with caution, as one can't guarantee accuracy

The image from the original paper: "VEHICLE VELOCITY FROM WORLDVIEW-2 SATELLITE IMAGERY" by Andreas Kääb described this phenomenon in 2011!

Airliner flying over sea in the WV-2 image over Rio de Janeiro. Left panel: NIR2/NIR1/NIR1 R/G/B composite with the pan band superimposed. The NIR2-pan-NIR1 shift indicates a speed of ~80 m/s (290 km/h) over the ~0.35 s time lag. Right panel: NIR2/Red- Edge/Red-Edge R/G/B composite with the cyan head and red tail indicating the airliner movement over the 3 × 0.008 s (~0.025 s) time lag, presumably combined with a slight y-axis misalignment between the bands.

not many people know this but it's possible to figure out how fast an object is moving from a satellite image... multiband hi-resolutions satellites today capture different wave lengths with slight time diffs between the capture.

Today we went from raw AIS datasets of ships to their origin destination graph... get on the waiting list we are days from a public launch and build sophisticated full stack geospatial apps in mins! geobase.app #gischat ❤️ #js #nextjs #movement #transportplanning
