# ----------------------------------------------------------------
# Revert to original Landsat Naming convention with YYYYDDD format
# ----------------------------------------------------------------

# created by: Jaime Hoffman

# adapted from:
# http://stackoverflow.com/questions/30307164/convert-yyyymmdd-filename-to-yyyyjd

# usage:
# 1) set filePath to directory containing landsat TIF files
# 2) set sceneID to match the beginning of the original Landsat file names*
# 3) set dateFormat to the format of your choice
# 4) set currentName to match the beginning of the current file names

# *this will be the platform identifier followed by the WRS path and row.
# The identifiers for landsat 5, 7, and 8 are LT5, LE7, and LC8
