This is version 3.3.11

xbrowse is an image browsing tool that works over the Internet. xbrowse uses
progressive transmission to facilitate browsing large images over the limited
bandwitdh supplied by the Internet. For more information see the xbrowse man
page. In order to compile xbrowse, you will need The X Window System (X11R5,
R6 or R6.1) and UNIX. To run xbrowse, you will need a workstation that is `on
the Internet'.

For the impatient: type `xmkmf; make Makefiles; make depend; make; make
install'. To test xbrowse, type `xbrowse'. Do not worry about error from
makedepend saying that some include files coud not be found.

Compiling xbrowse:

Any user can compile xbrowse and do so in just about any directory. However,
the user who installs xbrowse should ideally have write permission for the
directories where X11 binaries, application library files, and application
resource files are stored on the target system. If the person building
xbrowse does *not* have these permissions, then they can edit either Imakefile
or Makefile.dist and install xbrowse and its associated files in directories
where they do have write permission. To modify the Imakefile so that xbrowse
and its associated files are installed in a special set of directories,
change the definitions of BINDIR, LIBDIR, and MANDIR in the Imakefile. In the
Imakefile, these definitions are currently commented-out (since xmkmf
supplies default values for them). By uncommenting the definintions and
supplying your own values you will override the system defaults.

NB: When running `xmkmf' or `make depend' you will get some warnings about
files not found, ... ignore these since those warnings. Also, during
compilation of the FileComp widget, you will see one or two warnings; ignor

If you use site specific directories for your X11 application library, then you
should edit so that xbrowse will look in the correct directory for
the palette files (normally, X11 stores application specific library files in
`/usr/lib/X11/<app name>/'). Scan the begining of for
`palette_path' and make sure it is defined correctly. If xbrowse cannot read
its palette file, then it will print an error message to that effect and use
the default system palette. Generally the system palettes are unusable with

xbrowse-3.3.9 has been compiled on the following machines:

Machine                OS             X version        Compiler(s)
DECstation 5000/240    Ultrix 4.3     X11R5            gcc
DEC Alpha	       OSF/1.3, 3.0   X11R5	       cc, gcc
Sparc                  SunOS 4.1.3    X11R5,R6         gcc, gcc-2.7.2
SGI		       IRIX	      X11R5	       cc

To compile, type `xmkmf' followed by `make Makefiles', `make depend' and
`make'. Once you are satisfied with the build, type `make install'. If you
don't have imake, then follow the directions in Makefile.dist to tailor it to
your system, then type `make' and `make install'.

If you compile this code on any machine/OS combination not listed above,
please send me email ( describing what you did and/or
any lingering problems you have.

Using xbrowse:

xbrowse contains fallback resources (incorporated into the xbrowse source
code at compile time via George Ferguson's ad2c program) so it is not
necessary to install the XBrowse application defaults resource file for
xbrowse to work. However, if you do install the application defaults (this
happens automatically when you type `make install' - assuming you have the
privs to write to you app-defaults directory) you will still get the typical
sort of X11 client behavior re: resources.

The tar file contains the source code for xbrowse, various files used by the
program (the X11 resource file, ...) and other files such as this one. In the
diectory `palettes' there are several files which can be used as palettes for
xbrowse. We use the file named `color'. In this palette, white represents
very cold areas (0-4 C) and red represents hot areas (30 C).

xbrowse can be used to browse our ~20,000 image archive of AVHRR data. To
access this archive, run xbrowse without either the `-list' or the `-path'
options. xbrowse will prompt you for the start and end dates of the images
you wish to look at (e.g., if you entered 01/25/85 and 02/25/85 as the start
and end dates, then xbrowse would begin sequentially displaying all the
images in the archive that fall between those dates).

The archive starts on 1 April 1979 and continues to the present.  Each image
in the archive covers the area from latitude 60.575N longitude 96.222W to
latitude 9.399N longitude 33.768W.  The images use a linear projection and
the resolution of the data is 5km/pixel.

In addition, Jim Bisagni maintains an archive of data for the Gulf of Main
which can be accessed via xbrowse. To look at that archive use the `-server'
command line option and give `' as the machine name.
