A shell function to quickly grab the data for a given Landsat 8 tile ID from Google's servers
# This is a shell function to quickly grab the data for a given Landsat 8 tile ID from Google's servers
# For example:
# l8get LC81690352014169LGN00
# The echo at the end is to remind myself of the syntax for extracting bands 8, 4, 3, and 2. (Pansharp, Red, Green, Blue)
# On OSX this would go into your ~/.bash_profile file.
# Requires gsutil from https://developers.google.com/storage/docs/gsutil_install
# Most useful in conjunction with USGS' Earth Explorer: http://earthexplorer.usgs.gov/

Python script to efficiently concatenate S3 files
'''
This script performs efficient concatenation of files stored in S3. Given a
folder, output location, and optional suffix, all files with the given suffix
will be concatenated into one file stored in the output location.
Concatenation is performed within S3 when possible, falling back to local
operations when necessary.
Run `python combineS3Files.py -h` for more info.
