VEDA events explorer tool

[dzole0311]

Context

During the October 2024 Svalbard pod hackathon in Lisbon, our team explored the idea of an Events Explorer tool for visualizing STAC-based wildfire data from VEDA. This tool was imagined as a component of VEDA's new "Tools" content type. We came up with initial designs, but due to a lack of time we did not manage to build it.

I managed to partially re-visit the concept recently and explore the core functionality.

• Demo: https://wildfire-stac-events.netlify.app/
• Repo: https://github.com/dzole0311/wildfire-perimeters

The prototype uses wildfire data from OpenVEDA. To keep things simple, the demo currently uses a locally hosted set of GeoJSON features retrieved from the backend (I curled the back-end once and serve a limited set of geojson features hosted locally).

Features included in the app:

1. Event-based fire grouping
2. Ability to query the geojson features by params (e.g. max / min duration days)
3. Time-based event filtering via range slider
4. Toggle between 3D and 2D visualization modes

Acceptance Criteria

• Assess the feasibility of building on top of the prototype and integrating it into the new VEDA "Tools" content type (cc @faustoperez)
• Assess the possibility of switching the prototype to USWDS styles (cc @faustoperez)

This is great work Gjore, definitely interested in moving this forward 🎉

This is awesome, I'm glad you kept on prototyping! I would add we can get some feedback from folks on the instance side, especially those familiar with sub-daily imagery needs on GHG and an embedded viewer they're building there

We have a great collaboration with the NASA EIS Fire team and co-created this operational service that exposes this fire event data. It would be amazing to now also put an appealing UI like this on top.

Could we see a way forward where we

1. Iterate a bit more on the prototype, as @dzole0311 indicated
2. Use it as a very nice demo tool to showcase the concept of tools that integrate well with a VEDA Dashboard
3. Vet its usefulness with the subject matter experts at EIS

Unless we get a clear mandate from VEDA, we do not have a lot of resources to build this out further for EIS. But if folks get excited about this, that could come.

A tool embedded in a VEDA Dashboard is the best way for VEDA to get credit for this work, which has been one of the concerns. 👌

GHG Center now has two of these event viewers:

• Methane plumes (EMIT): https://staging.earth.gov/ghgcenter/custom-interfaces/emit-ch4plume-v1
• Methane plumes (GOES): https://staging.earth.gov/ghgcenter/custom-interfaces/goes-plume-viewer

Point timeseries viewers is a second type:

• https://earth.gov/ghgcenter/custom-interfaces/nist-interface/?agency=nist&region=in
• https://earth.gov/ghgcenter/custom-interfaces/noaa-gggrn-ghg-concentrations/index.html?ghg=co2&frequency=all
