Net : Network misclosures

Product Description

This product shows various indicators of the quality of the time series inversion, which allow to obtain phase delay time series from a stack of interferograms.

The geotiff file has 5 bands:

• band 1 shows the rms misclosure of the interferogram network for each pixel (in rad)

• band 2 shows the number of interferograms used in the time series inversion for each pixel

• band 3 shows the number of images used in the time series inversion for each pixel

• band 4 is a proxy for the temporal coherence, computed from triplets (between 0 and rlooks_unw): it is a multilooked version of the proxy for the temporal coherence given in TCoh product

• band 5 is a proxy for possible bias, computed from triplets (in rad)

• band 6 is number of unwrapped interferograms greater of 8 months per pixel. It can be considered for a mask wrt the biais

• band 7 can be 0, 1, or 2. 0 means OK. 1 means layover (i.e. area with two different altitudes in the same pixel). 2 means shadow (area with a very low amplitude)

The png file has one band:

• band 1 is the misclosure of the interferogram network for each pixel

Available products

Network misclosures are computed in one resolution:

• runw = 8 (resolution of unwrapped interferogram)

Network misclosures are computed in two geometries:
