is it live? Like can a get a pic of a place made at day light in the last 24 hours?

- plant99 6y agoHi, not yet. It searches for all Landsat 8 images on AWS with lowest cloud cover. But even at it's full potential, Landsat 8 gives a temporal resolution of 14 days for a location, iirc.
- kylebarron 6y agoLandsat 8 has a 16 day repeat cycle
- plant99 6y agoYess, thanks for the correction. "The satellite has a 16-day repeat cycle with an equatorial crossing time: 10:00 a.m. +/- 15 minutes." from USGS website.
- enriquto 6y agoFor a little more effort you could "interleave" the Sentinel 2 images as well, which are of a similar resolution and also have a simple access API.
- plant99 6y agoOh yes, there are plans to integrate Sentinel images as well, but the data fetch layer has to be worked on to handle auth/AWS config to fetch data from buckets. So released with Landsat 8 first, and I think sentinel 2 has better resolution, up to 10m, if I am not wrong. So it'd be a lot better if Sentinel 2 integration were in-place.
- enriquto 6y agoThere's also this, if you are interested in downloading timeseries as a whole: https://github.com/cmla/tsd https://github.com/cmla/tsd It supports sentinel 1/2/5p, landsat 8 and a few other satellites if you have the required API access identifiers. The idea is to fetch data not from buckets but from the actual sources, so the underlying philosophy is a bit different.
