(1) azelplot README ------------------------------------------------------- by Ronni Grapenthin, 26 May 2013 azelplot is a fork of Steve Hilla's cf2sky, a program that generates a GMT script with corresponding input files, which will plot these data (in UNAVCO's compact 2 file format) in a skyplot (azimuth-elevation). cf2sky was originally for Windows; azelplot can be considered the Linux port. It should compile under Windows, but I never tested it and I doubt the file formats will cooperate. Under (2) you find the original instructions by Steve Hilla. Those explain where to get and how to install some of the required packages. I added a Makefile to this version, which you should review and edit to meet your needs: > make all will create a binary ``azelplot'' and copy this to /usr/local/bin. > azelplot INPUTFILE Is how to call the program. INPUTFILE is a configuration file that contains the following information in the respective lines (see okfg194.inp): Line-no Expected Information -------------------------------------------------------------------- 1 Title in the output plot 2 Plot start time (YYYY MM DD HH MM SS) 3 Plot end time 4 Orbitfile (incl. path) in SP3a format 5 Cutoff angle, no information will be shown below that angle. 6 Rinex observation file (incl. path) 7 Data file to be plotted (in UNAVCO compact 2 format), if it ends in `.rms' the output unit will be `cm', else `m' ( 8 Highlight start time ) ( 9 Highlight end time ) The last 2 lines are optional. When used the indicated section will be highlighted in red. If INPUTFILE is not given, the program looks for file ``azelplot.inp'' in the current directory. Calling azelplot will create several output files, one is xxxx*.bat, where xxxx is a 4-char station ID. This is a GMT shell script that needs to be executed to generate the plot. The other output file is cleanup*.bat, which can be called after the plot has been generated to delete all the temporary files. The package comes with a ``test'' directory which contains the orbit file, rinex file, phase delay file (.rms), and INPUTFILE (rvbm_094.inp) to plot phase delay on 2009-04-04 along the skytracks of the satellites. (2) Instructions for compiling and using program CF2SKY ------------------------------------------------------- by Steve Hilla, 22 March 2004 The CF2SKY program requires four *.cpp files and five *.h files: consts.h, physcon.h, datetime.h, rinex.h, intrpsp3.h, skyplot.cpp, datetime.cpp, rinex.cpp, and intrpsp3.cpp. The program was originally compiled using Borland C++ Builder Professional Version 5.0 (Build 12.34) Update Pack 1. It was compiled on a PC running Windows NT 4.0 Build 1381: Service Pack 6. If you are using Borland C++ Builder, you should be able to load these files into a directory and get the program to compile; the other files you need are cf2sky.bpr, and cf2sky.bpf. The last two files are specific to Borland C++ Builder. There are four example data files included: cha22170.02o, brdc2170.02n, cha22171.02o, and cha22171.mp1. The first two files can be run through TEQC to create the third and fourth. The CF2SKY program can be used on the *.mp1 file, the cha22171.02o file, and the brdc2170.02n file to create a postscript file called skyplot.ps . Other files: A PC-executable file is included: cf2sky.exe. One should be able to run this program on the example TEQC plot file, cha22171.mp1, to create a postscript file called skyplot.ps using the given cf2sky.inp file. This can only be done if the GMT software is loaded on the PC. The resulting PostScript file, skyplot.ps, can then be viewed or printed if the Ghostview software is installed on the PC. Installing GMT and Ghostview: A Vol.6, No.3 paper "A new plotting program for Windows-based TEQC users", gave the details about where to find GMT and Ghostview and what files to read for instructions on how to install these software suites on your PC. For convenience, the instructions are repeated below (see "Downloading TEQC, GMT, and Ghostview"). After installing the GMT (Generic Mapping Tools) software on the PC make sure that it is working by typing a GMT program name at the DOS command prompt (e.g. type 'gmtset'). This should start the gmtset program that is part of GMT and give you the usage message for program gmtset. If this does not occur then the GMT software is not yet active on your PC and you will not be able to successfully run program cf2sky.exe. After installing the Ghostview software you can verify it is working by running the gsview32.exe program from its icon on your desktop and then trying to view the example skyplot.ps file included on the website. Downloading TEQC, GMT, and Ghostview: The TEQC program can be downloaded from the UNAVCO website: http://www.unavco.ucar.edu/data_support/software/teqc/teqc.html From the main TEQC page, scroll down to the section entitled Microsoft Windows and DOS zip files. Then download the appropriate zip file for your PC's operating system. The Generic Mapping Tools (GMT) software can be found at the University of Hawaii, School of Ocean and Earth Science and Technology website: http://gmt.soest.hawaii.edu Scroll down to the section entitled "GMT master and mirror sites". Click on one of the mirrorsites and download the README.GMT file. All of the files needed for Windows-users are listed as *.zip files; this file explains what each *.zip file contains. To start out simple, the reader may wish to download only the following files: GMT_exe.zip, GMT_share.zip, GMT_suppl_exe.zip,GMT_pdf.zip, and netcdf-3.5.0.win32bin.zip. The CF2SKY program uses GMT to create fairly simple XY-plots. But the GMT software can also be used to generate high-quality maps using several different coastline data sets. The reader may wish to download these different coastline files later on for the purpose of building maps. There are also source code files that the reader may wish to download at a later time. Once the GMT software has been unzipped, examine the README.WIN32 file in the main GMT directory for instructions on how to configure your PC to run GMT. The AFPL Ghostscript software is available from the Computer Science Department at the University of Wisconsin: http://www.cs.wisc.edu/~ghost First click on "Obtaining AFPL Ghostscript 7.04". The acronym AFPL stands for "Alladin Free Public License". Then scroll down to the section entitled "Windows 95, 98, ME, NT, 2000 or XP". Download the files gs704w32.exe and gsv43w32.exe. Execute the first file to install Ghostscript version 7.04. Then run gsv43w32.exe to install GSview. Ghostscript/GSview will require about 17 MB of disk space. The GMT software, using just the five *.zip files mentioned above, will require about 22 MB of disk space. Since both of these software packages are actively maintained, the reader can expect that each of the above mentioned websites will eventually contain future versions of the software.
