DESCRIPTION
This program is part of GMTSAR.
USAGE: sbas intf.tab scene.tab N S xdim ydim [-atm ni] [-smooth sf] [-wavelength
wl] [-incidence inc] [-range -rng] [-rms] [-dem]
input:
intf.tab
-- list of unwrapped (filtered) interferograms:
format:
unwrap.grd corr.grd ref_id rep_id B_perp
scene.tab
-- list of the SAR scenes in chronological order
format:
scene_id number_of_days
note: the number_of_days is relative to a reference date
N -- number of the interferograms
S -- number of the SAR scenes
xdim and ydim
-- dimension of the interferograms
-smooth sf --
smoothing factors, default=0
-atm ni --
number of iterations for atmospheric correction, default=0(skip atm correction)
-wavelength wl --
wavelength of the radar wave (m) default=0.236
-incidence theta --
incidence angle of the radar wave (degree) default=37
-range rng --
range distance from the radar to the center of the interferogram (m) default=866000
-rms --
output velocity uncertainty grids (mm/yr): rms.grd
-dem --
output DEM error (m): dem_err.grd
-mmap --
use mmap to allocate disk space for less use of memory
-robust --
only work with -atm turnned on, estimate velocity with records that has atm
correction
output:
disp_##.grd
-- cumulative displacement time series (mm) grids
vel.grd
-- linear regressed velocity (mm/yr) grids
example:
