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…

RemotePixel.ca[0] has my favorite interface for discovering Landsat 8 images.

Also, 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/

S2: http://sentinel-pds.s3-website.eu-central-1.amazonaws.com/

You 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.

https://landsatonaws.com has a nice interface I think.

API is https://landsatonaws.com/{path}/{row}/{scene}

They should apply deep learning to this :)

If we used deep learning then we probably wouldn't have got into the journal 'Remote Sensing of Environment'

To get into top journals it is really about simple method + novel idea + good story.

The same holds for top Finance journals like 'Journal of Finance', etc.

A 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.

Based on my readings, 'incomprehensible method + novel idea + good story' seems to work pretty well too.

Looks like someone has: Deep Learning-Based Classification of Hyperspectral Data http://ieeexplore.ieee.org/abstract/document/6844831/

This is exactly what I was hinting at: IEEE journals (TGRS, etc.) are filled with deep learning and machine learning on satellite imagery papers.

They are more tech focused journals and have less impact.
