DTs : Time Serie

Product Description

The Time-series geotiff file come from a cube product (an envi file). The cube file contains phase delay images at each time step of the time series. It is cumulated with respect to the first date. However, the spatial reference is set to the origin of a linear fit through the time series for each pixel. This representation avoids the APS of the first image to appear in negative on all other dates. However, it is not ideal in case of strongly non linear deformation.

The geotiff file has nb_image bands (nb_image is the number of time steps). Each band is given in rad along the LOS, positive away from satellite.

• Band name gives the date of the time step (YYYY-MM-DD)

The png file has 1 band:

• band 1 is first time step of the cube.

Available products
