powershell script to copy gps-metadata between image files
# script to copy GPS metadata between files based on names.
# implemented for photos from Lumia 1020 phone which stores images in two sizes,
# one of them (low resolution image) has GPS but the other (high resolution image) does not!
# requires ExifTool: http://www.sno.phy.queensu.ca/~phil/exiftool
# author: Harmish Khambhaita, v0.1, 13/04/2016
# specify directory to process photos
$rootFolder = "C:\Users\your_name\Pictures\lumia_1020"
