The other satellites have orbits distributed with the data.\n       https://topex.ucsd.edu/gmtsar/downloads/\n\n3) Go to the gmtsar directory and enter:\n\n       autoconf\n\n4) Configure GMTSAR:\t\n   Run the configure script.  To see all options, run\n   \n       ./configure --help\n\t\n   Most users will simply run\n   \n       ./configure --with-orbits-dir=\u003corbitsdir\u003e --prefix=\u003cinstalldir\u003e\n\t\n   For example, you might run\n\t\n       ./configure --with-orbits-dir=/usr/local/orbits\n\n5) To build all executables, type\n\n       make\n       make install\n\n6) test the commands: gmt, esarp, xcorr, conv, gmtsar.csh, etc.\n   If using C-shell you may have to type rehash first. \n   If this does not work then make sure the \u003cinstalldir\u003e is in your system $PATH or $path.\n\n__RUN__\n\n1) GET DATA. There is an example data set at our website:\n       https://topex.ucsd.edu/gmtsar/downloads/\n\nUncompress the file and then unpack with tar.\n\n2) ORGANIZE the DISK. The standard GMTSAR run has the following directories. \n\n  raw    SLC    topo   intf\n\nraw - contains the original data.\n\nSLC - contains the single look complex images derived from the raw data.\n\ntopo - contains a digital elevation model for the area in geographic and ultimately radar coordinates.\n\nintf - contains subdirectories with the possible interferograms (only 1 for this example).\n\n3) MAKE DEM \n\nEnter the following command to make a NETCDF file of heights above the ellipsoid from SRTM.  This used the GMT dem \ngeneration facility.\n\tmake_dem.csh W E S N [mode]\nPlace the file dem.grd in the /topo directory. \n\n4) EXAMPLE RUNS\n\nThere are complete examples for each data type at the following web site:\n      https://topex.ucsd.edu/gmtsar/downloads/\n\nTo process a pair interferogram, try `p2p_processing.csh`, or `p2p_S1_TOPS_Frame.csh` for Sentinel-1 TOPS data and `p2p_ALOS2_SCAN_Frame.csh` for ALOS-2 ScanSAR data. For batch processing, see instructions in the GMTSAR documentation (http://topex.ucsd.edu/gmtsar/tar/GMTSAR_2ND_TEX.pdf) or the Sentinel-1 time-series recipe (http://topex.ucsd.edu/gmtsar/tar/sentinel_time_series_5.pdf).\n","project_url":"https://awesome.ecosyste.ms/api/v1/projects/github.com%2Fgmtsar%2Fgmtsar","html_url":"https://awesome.ecosyste.ms/projects/github.com%2Fgmtsar%2Fgmtsar","lists_url":"https://awesome.ecosyste.ms/api/v1/projects/github.com%2Fgmtsar%2Fgmtsar/lists"}
