LAT File Formats

Single look complex SAR data (<orbit>.slc)

Two formats for SLC data are supported.

In the first format the SLC data are in complex floating point representation, each complex sample consists of two 4 byte floating point numbers, real and imaginary part. There is no file header, or zero padding of the data. Each record corresponds to a single range line. The number of samples/line and the number of lines is specified in the SLC data parameter file SLC_par or if available in the MSP processing parameter file.

The second format is the format provided by ESA Processing Facilities (PAFs). Real and imaginary part of the SLC data are in 2 byte integer format. File header, or zero padding of the data as described in the CEOS leaderfile. Each record corresponds to a single range line. The number of samples/line and the number of lines is specified in the SLC data parameter file SLC_par or if available in the MSP processing parameter file.

Complex data (*.int, *.flt, *.sm, *.slope)

Complex valued data (for example the interferogram) saved as pairs of 4-byte floating point numbers (real part followed by imaginary part). Image width and height correspond to the number of range and azimuth pixels, respectively. No header or zero-padding is used. Image width and height are given in the ISP processing/offset parameter file.

Real data (*.pwr1, *.pwr2, *.cc, *.unw, *.hgt, *.rpwr1, *.rhgt, ...)

Real valued data saved as 4-byte floating point numbers. Image width and height correspond to the number of range and azimuth pixels, respectively. No header or zero-padding is used. Image width and height are given in the ISP processing/offset parameter file.
