Stitching tiles with Python
Original credit to Ossum from Instructables for publishing the code which got me 99% of the way there.
Massive props to Ian Douglas who did all the work to make this an even awesomer thing.
##tile-stitch.py
Reads extents from a single CSV file and downloads tiles within the extents and then stitches them together into a large file
##geojson_to_extents_csv.py
Reads the 'bbox' property from a GeoJSON file and outputs the coordinate pairs to a massive CSV
