Doris 8 – One dataset, one template

1. One interferogram, one template

Doris uses 8 input.* files (input.m_initial, input_resample, etc.) that “run -g” command generates to setup parameters. It’s time consuming to modify them one by one for different interferometric pairs. However, we can merge those 8 into 1 and make a common input file (i.e. Env.dorisin) for the whole dataset.

Read these input.* file and Doris’s manual and you would find that the InSAR processing of Doris is made up of a series of PROCESSs. One PROCESS for one function, with input parameter listed below on the input.* file. If we put all these PROCESSs’ announcements and parameters together in one file, i.e. ASAR.dorisin for Envisat ASAR data, we could run the whole process chain with one single command:

doris Env.dorisin

 

2. One dataset, one template

For data with different date within one dataset, just change the path of master and slave data; for different datasets with the same sensor, change the parameter of DEM; and for different satellite data, create a new template file, like TSX.dorisin for TerraSAR-X data.

Furthermore, for one dataset, i.e. multi-temporal data, if we create soft links for the SLC with the same name for master and slave respectively, a common template file could be created and used for the whole dataset. Put these soft link creation scripts and Doris calling script together into one file, i.e. run_Env.sh, and we can run this file to get everything working!

./run_Env.sh
