Show HN: Forest Watch
https://koenvangilst.nl/labs/forest-watch
Keep track of forests in your area by viewing changes in tree cover over time.I’ve build this as a demo of what you can do with the ArcGIS library and the geo data that is offered by Global Forest Watch and Esri. Don’t forget to click the history button.
Works best on desktop!
The demo is build with React and open source: https://github.com/vnglst/koenvangilst.nl/tree/main/app/(bla...

The crux of the issue is each importer requires verifiable satellite evidence. I could see suppliers using this site to generate their compliance statements!

And a great use case for mass-market satellite imagery.
There's no arguing that f.ex. n-2 years ago there was tree cover in imagery of an area, that's now gone.
It seems that the gain/loss layers do render, but it can currently take a very long time. The user doesn't see whether data is still fetching or if there are no changes/data for the displayed region. Perhaps you could reflect this in the UI somehow?
I will make sure to check it out later, once it's no longer being hugged.
I also wanted to ask for a 'go to my location' button, only to find out that it is there in the bottom right corner. Perhaps it would be useful to make it more prominent?
I was helping with a project for the Audubon Society some years back and we were pulling these images via ESA sweeps, which were all available via AWS (puller pays, which was quite inexpensive). However, it required some complex geometry and post-processing. Did you have to do something similar?
There’s also some logic involved in making sure the user only sees the layers with new data in it. That’s running on the client and it’s quite heavy.

And even if it is local, the eco footprint is huge (also a big deal for water constrained areas).
