An interesting resource: EO Browser

[Daniel F]

I was looking to get archival photography for some basins in the Sierra, and stumbled upon EO Browser. The features I need are available for without cost. It tends to have more powerful options than, say, CalTopo’s archive feature, but it is less convenient to annotate with one’s notes. You can upload a GPX or GeoJSON, though, and though it won’t save it, it’ll draw it for you.

Here’s an example, near Potluck Pass in 2017, the last extremely high Sierra snow year, using the NDSI layer, which can work to some degree through cloudcover as it combines short-wave infrared data:

I hadn’t seen it mentioned in the forums anywhere based on a quick search, but it seems like something that could be quite useful.

EO Browser is well worth visiting. If you Google it though, some of the links go to a page that invites you to sign up for a business account. Most backpackers will be happy with the free viewer. Has 10 meters per pixel imagery, refreshed every four days or so.
