#SatGPT is an app that lets you talk to satellite imagery.

We've got some more work to do before it's polished, but I'm pretty psyched about the results so far.

Powered by @Element84 @STACspec @LangChainAI @Panel_org @HoloViz_org, huge thanks to @ivanziogeo & @MarcSkovMadsen.
We'll be working hard the next few days to add spectral indices (back) to the app along with some other nice-to-haves. @dmlmont

If I wake up to some r/ts from the STAC gang I have a special video to add here.

In all seriousness huge thanks to E84 and others like @OurRadiantEarth @opengeospatial @developmentseed @GeoSkeptic for bringing EO to the people.

Thanks for the interest, y'all. Here is a bit of an intro/ peek behind the curtains of #STAC capabilities.

I'll add one or two more things to this thread before going heads down again for the week. 😉🤖

Of course, everyone just wants all the bands/ all the indices.
That's what makes #spyndex a natural choice for #SatGPT. Here's a quick test of the original indices in @ivanziogeo's awesome demo for viewing S2 data, more coming...
Also powered by @STACspec @Panel_org @LangChainAI!
@ivanziogeo @STACspec @Panel_org @LangChainAI I still have a few to-do's before this is usable for others, but I'm close!
In the meantime, check out @dmlmont's great app for browsing/ researching indices and... ahem... let me know your favorites.

Or if you have some local NetCDF's kicking around, you can try Ivan's original viewer here:
