Global ALOS mTPI (Multi-Scale Topographic Position Index) (CSP/ERGo/1_0/Global/ALOS_mTPI)
Version 1.0
The mTPI distinguishes ridge from valley forms. It is calculated using
elevation data for each location subtracted by the mean elevation within a
neighborhood. mTPI uses moving windows of radius (km): 115.8, 89.9, 35.5,
13.1, 5.6, 2.8, and 1.2. It is based on the 30m “AVE” band of JAXA’s ALOS
DEM (available in EE as JAXA/ALOS/AW3D30_V1_1).
