GEOL 701h Radar Imaging Lab Guide

(or link to http://earth.esa.int/services/pg/pgerssarraw.xml ), and read about the ERS-1/2 Synthetic Aperture Radar (SAR) Annotated Raw Data Product. Take a tour of all of links on this page so you know what is there.

II. Catalog Tools for identifying available ERS Satellite Radar data:

Start at: ESA earth Observation User Service page.

at: http://earth.esa.int/services/

Select Catalogs (or link to http://earth.esa.int/services/catalogues.html)

1. Locate and select Descw: (or link to http://earth.esa.int/descw/)

Descw - an off-line catalogue and image browser (apparently available for windows only) download from http://earth.esa.int/descw/ Install this program on your own windows computer system.

Assignment (due Sept 19th 03): Make a excel table of the available ERS 1 and 2 SAR scenes over Reno with headings for Mission (ERS 1 or 2) Track, Frame, Orbit, perpendicular and parallel baseline offsets and Doppler offsets. Select only one or two of the best covering track and frame locations for Reno. Because this program does not have an intuitive set of menus and actions I will offer training on its use. We will add information from other sources to this “master table” as we proceed.

2. Locate and select EOLI (or link to http://odisseo.esrin.esa.it/)

Select the no-Java version. I generally select the No-Java version because it seems to run with less problems. Use this related on-line catalog program to search for Reno area ERS 1 and 2 SAR scene pairs that are suitable for forming an Interferogram. Here we want to identify particular scene pairs that meet our particular specifications for InSAR processing and analysis rather than identify all of the SAR individual scenes as we did in the off-line catalogue. These searches need to be focused not only by location (Track and Frame) but by a specific date interval for each scene in the pair) and baseline requirements - if this is not done too many combinations will be returned to be useful. Again, I will provide training to get you going on this.

III. The WinSAR ERS 1 and 2 SAR Scene Archive.

http://www.winsar.scec.org/ Actual data access requires a password.

http://topex.ucsd.edu/winsar/ This older site offer a good overview of WinSAR but the data indexes are not current.

I have converted the WinSAR scene index (current as of 26 Aug 2003) to an excel spread sheet available here.

IV. ROI_PAC InSAR Processing Software Documentation

This software is installed on the ABLE SUN Blade1000 computer.

Important ROI_PAC references:

Students will be expected to become familiar with the types of information and resources available in each of the following documents and links.

1) Chris Okubo’s ROI_PAC user guide pdf (this is a 4.3 mb reduced resolution version)

This guide will serve as one of our key processing procedure references; however, we will revise some of the procedures (e.g. DEM set up).

2) Buckley’s Thesis Ch3 ROI_PAC Documentation pdf.

This is the only available documentation on the signal processing procedures employed within ROI_PAC. Sections of this document will be assigned as necessary reading later in the course.

3) UC Berkley’s (David Schmidt’s) ROI_PAC resources web page:

http://www.seismo.berkeley.edu/~dschmidt/ROI_PAC/

This is one of the top information resources on ROI_PAC processing.

4) David Schmidt’s ROI_PAC Appendix A: Resource Guide (16 pages) pdf

Be sure to printout and read this document.

5) ROI_PAC Support at Open Channel Foundation

http://www.openchannelfoundation.org/project/view_support.php?group_id=282

This is one of the top information resources on ROI_PAC.

6) ROI_PAC on-system Software Documentation <<<<<

Original documentation for set-up procedures and processing routines may be found in hyperlinked format on the

ABLE5 Sun by opening a web browser on the local file:

file:/dk01/users/insar/ROI_PAC_DIST/ROI_PAC/DOC/HTML/index.html

Specific ROI_PAC Procedures and Instructions for 701h Fall03

1) Instructions for First Time Processing on the ABLE5 Sun Blade 1000

Guide followed in class demonstration on Sept 9, 03

Modified by glo from D. Schmidt’s instructions. <<<<<

V. Sun Blade1000 User Documentation

Students will need only a minimal initial understanding of Unix to begin learning about the Sun ROI_PAC system. Please wait until you have been introduced to the necessary system basics and precautions before beginning to work with files outside your home directory. Over the semester you will accumulate more advanced Unix knowledge, including editing of existing perl and shell program scripts. The details to system commands you may need to understand are provide in the first reference below.

For system commands the single most useful reference is the Solaris Advanced Users Guide provide here as a pdf This is document is also available on-line at Sun’s documentation web site at. http://docs.sun.com/db/doc/806-7612 This document provides answers to questions such as: ‘how do I change my password?’ but it is not useful to as a beginners guide to UNIX or Solaris.

Introductory Sun Desktop ‘windows style’ how to documentation is available in on-screen help files once you’ve logged-on to the ABLE5 Sun.

UNIX references:

If you are new to UNIX/SUN systems, I recommend staring with the following UNIX references and tutorials

Introduction to UNIX - a 4 page pdf file - from Alaska Satellite Facility's (www.asf.alaska.edu)

A UNIX Tutorial for Beginners can be found at:

http://www.ee.surrey.ac.uk/Teaching/Unix/

A good web-based Unix help page is: http://www.gw.com/UNIXhelp/index.html

Another is at: http://kb.indiana.edu/data/afsk.html#info

A Unix Command Line Summary is available as a local file here: Surviving the Unix Command Line (Note the links for the full details on each command are broken.)

Perl language references:

Introduction to Perl Programming http://www.vis.ethz.ch/manuals/Perl/intro.html

Perl 5.8.0 Documentation (a useful reference ) http://www.perldoc.com/perl5.8.0/pod/perlintro.html

VI. MS Windows to SUN communication programs

MI-X: an X-Windows terminal emulation program to be run on a windows computer.

A $25 program with 15 day free trial.

WS_FTP95_LE: an FTP program for copying files between a Windows and Sun computers. Free to non-commercial users.

VII. DEM data Resources

Main web site for Shuttle Radar Topographic Mission products: http://www.jpl.nasa.gov/srtm/cbanddataproducts.html

USGS seamless data server for NED and SRTM DEM data: http://seamless.usgs.gov/

This seems to currently be the best source of DEM data for ROI_PAC.

FTP link for Space Shuttle Radar Topographic mission SRTM DEM data: http://edcwww.cr.usgs.gov/pub/data/srtm/

these are generally provide here in one degree tiles.

Fialko’s notes on ROI_PAC DEM usage: http://igpphelp.ucsd.edu/~fialko/roi_pac.html

Oppliger’s notes for converting SRTM DEMs to ROI_PAC format using ENVI (doc) <<<<<

USGS NED DEMs: Note the above instructions for SRTM DEMs should work equally well with NED DEMs taken from the same USGS seamless data server (however, I have only partially test this). Because NED DEMs, do not generally have data holes, the step to fill holes is skipped. Byte swapping is the only necessary data-conditioning step. NED DEM data are in the NAD83 horizontal datum and NAVD88 vertical datum. These are generally within one meter of both the WGS84 horizontal coordinates and the WGS84 Geoid vertical reference surface used in the SRTM data, so their conversion to the SRTM datums can be safely ignored for ROI_PAC processing.

Chris Okubo’s ROI_PAC user guide pdf (this is a 4.3 mb reduced resolution version)

Contains a procedure for using GMT software to make ROI_PAC DEMs. pages 12-17.

VIII. Course Lab Schedule

ROI_PAC Processing Progress Schedule (doc). (Added Sept 15) <<<<<<

This schedule defines how the class will proceed with training and final project processing using ROI_PAC.

Important Reminder about using the SUN workstation

When cleaning up after your test ROI_PAC runs ...

Shred your trash files immediately after you send them to the trash!

Then check your trash again before you disconnect.

The system may lockup if our 2GB home directory is filled with trash.

All files in the Trash may be shredded. Files over about 500 MB should be directly removed with the: “rm yourfilename” command. Procedure: open a terminal or console on the desktop, verify your current directory with the pwd command, then and typing rm yourfilename. This avoids the trash can altogether.

If you are having an operational problem with the ABLE5 Sun that may also be affecting other, users please let me know ASAP by calling my office at 784-7056 (I tend to be around 9a-7 pm). if you don’t get a hold of me by phone, email both me and Don L Sawatzky (dons@mines.unr.edu).
