## NOTE: Computing the -ts parameter:
|
|
15
|
# 1) Calculate difference between bounding latitude (longitude) pairs,
|
|
16
|
# 2) multiply by 120 (3600 arc seconds per degree / 30 arc second resolution)

|

# NOTE: This script uses the SRTM version 4.1 data distributed by CGIAR (6001 x 6001 tiles)
