If you're looking to get into Landsat imagery yourself, I highly recommend the command line tool landsat-util[1] (although you do need to install it using Python 2). It allows you to search with lat/lon pairs, cloud cover, etc, and comes with tools to automatically do the band combining for you so you can have easy real-color images.
I find the the browser-friendly tools like LandsatLook[2] or Earth Explorer[3] to be more difficult to use, but if you're interested USGS has posted some great tutorials for them on YouTube[4]. There are also some interesting ideas about how to use the data itself beyond just creating pretty pictures.

- daleroberts 9y agoEven cooler is when you take landsat-util and visualise results directly in your terminal, see here: https://github.com/daleroberts/tv https://github.com/daleroberts/tv
- flyaway 9y agoThat's fantastic! A perfect combination of tech and use case.
- daleroberts 9y agoOnly a cheap trick, but a useful one :-)
- llccbb 9y agoRemotePixel.ca[0] has my favorite interface for discovering Landsat 8 images. [0] https://remotepixel.ca/projects/satellitesearch.html https://remotepixel.ca/projects/satellitesearch.html
- JorgeGT 9y agoAlso, both Landsat and Sentinel (which is still free but has higher resolution, 10m/px, without needing pansharpening) data is available on AWS: L8: https://aws.amazon.com/es/public-datasets/landsat/ https://aws.amazon.com/es/public-datasets/landsat/ S2: http://sentinel-pds.s3-website.eu-central-1.amazonaws.com/ http://sentinel-pds.s3-website.eu-central-1.amazonaws.com/
- llccbb 9y agohttps://landsatonaws.com https://landsatonaws.com has a nice interface I think. API is https://landsatonaws.com/{path}/{row}/{scene} https://landsatonaws.com/{path}/{row}/{scene}
- dublinben 9y agoYou can also use Landsat imagery to contribute to OpenStreetMap right from within the JOSM editor. [0] It is just one of many built-in imagery providers with varying levels of detail. [0] http://wiki.openstreetmap.org/wiki/Landsat http://wiki.openstreetmap.org/wiki/Landsat
- Veratyr 9y agoA little off topic but are you aware of anywhere that provides high resolution night-time imagery? So far I've only been able to find a little from Himawari-8.
- daleroberts 9y agoVIIRS DNB Nightly Mosaics can be found here: https://ngdc.noaa.gov/eog/download.html https://ngdc.noaa.gov/eog/download.html The Visible Infrared Imaging Radiometer Suite Day-Night Band (VIIRS DNB) images the entire Earth nightly at a resolution of about 750 meters. Suomi NPP orbits the Earth 14 times per day on a 16-day repeat cycle. The average time at which images are taken is near 01:30 in local solar time, but can vary by over an hour depending on latitude and the particular cycle.
- Veratyr 9y agoThanks! That's the kind of imagery I'm looking for but not the resolution. I should have made it clearer but what I'm looking for is images with resolution like in this article: http://www.bbc.co.uk/news/resources/idt-sh/syria_from_space_english http://www.bbc.co.uk/news/resources/idt-sh/syria_from_space_... They claim to have got these from NASA but the resolution looks a hell of a lot finer than 750m, it looks more like 1m-5m; you can see individual streets in the Raqqa timelapse. They link to http://www.bbc.co.uk/news/resources/idt-sh/syria_from_space_english http://www.bbc.co.uk/news/resources/idt-sh/syria_from_space_... but it just mentions VIIRS again.
