  <dc:description>This dataset contains the median glacier surface velocity for the Pamir-Karakoram-Himalaya for the years 1999-2003 (Landsat 7 SLC-ON only). The velocities has been obtained by feature-tracking of Landsat images spaced 1 year apart.

The folder contains the following fields at 120 m resolution in GeoTiff format:

- the velocity magnitude 'vel' (meters per year)

- the x/y velocity components x_vel/y_vel (meters per year)

- the associated errors err, x_err, y_err (meters per year)

- the standard deviation of all the merged velocities 'std' (meters per year)

- the number of image pairs that have been merged in the median

 

I recommend filtering data with error larger than 10 m/yr.
