File Structure
| File Suffix | File Structure | File Format | Data Type |
|---|---|---|---|
| *.slc, *.int, *.amp | cpx | BSQ | complex |
| *.cor, *.unw, *.hgt | rmg | BIL | floating point |
cpx = complex values; alternating real and imaginary pixel values
rmg = alternating lines of amplitude and phase
BSQ = band sequential
BIL = band interleave
Output File Names
Important files created by ROI_PAC are listed below. Not all of the files listed are created during every processing scenario. For example, additional files are created when you include a seismic model in the processing. Capital letters designate where names will vary according to the input parameters in param.txt.
