Readme2 File

	At this level of the CDROM, the user will find this readme2.txt 
file and a directory named "viewsoa."  This view named "viewsoa" is the 
view for Library soamafr and the Reference Library.  The view is for use with 
VPFVIEW software version 2.1.  The directory has three standard files: 
env, themes and default.sym.  Refer to VPFVIEW online help for 
additional information on these standard view files.  The "viewsoa" 
view has been tailored to contain themes and associated symbols for 
those VMap Level 0 (VMap0) features that actually occur within this 
specific VMap0 library.  VPFVIEW allows users the option to adjust the 
colors and symbols of a view if desired.

	The actual VMap0 data can be accessed directly from the CDROM.  
If the user has the free disk space, the VMap0 data (356.2 megabytes) and 
reference library (6.5 megabytes) can be copied to a hard drive.  This 
will improve the speed at which VPFVIEW displays and queries the data.


Installing Views to VPFVIEW Version 2.1

	The following instructions are for installing "viewsoa" to the 
user's hard drive for use with VPFVIEW Version 2.1.  The view must be 
copied to your system's hard drive because any changes you make cannot 
be saved to the CDROM.  Copy the entire contents of the subdirectory 
named "viewsoa" to your work directory on your system and change the name 
to end with a % (percent sign). Examples of copy commands:

	UNIX		cp -r /cdrom/view/viewsoa  /data/vmap0/viewsoa%
	DOS		xcopy/e d:\view\viewsoa  c:\vmap0\viewsoa%
	Win/NT		Using File Manager or Explorer drag "viewsoa" 
			to c:\vmap0 and rename to end with a %

	UNIX Note: Where /cdrom is your CDROM's mount point. The user 
can substitute other pathnames for "/data/vmap0." The directory and 
files will be copied with the READ ONLY attribute set.  You can choose 
to change the attribute and make it READ/WRITE or follow the steps below, 
and the VPFVIEW application will copy the view directory to another 
directory that will have read/write permission.

	DOS/Win/NT Note: Where d: is your CDROM drive and c: is your 
hard disk drive.  The user could substitute other pathnames for "\vmap0." 
The directory and files will be copied with the READ ONLY attribute set.  
You need to turn off the READ ONLY attribute, to make it READ/WRITE.

To install "viewsoa%" to VPFVIEW 2.1:
	1)  Start the VPFVIEW 2.1
	2)  Using the mouse, pull down the File menu
	3)  Move the mouse to the View option and open its submenu
	4)  Move to the "Install..." option and click on it.

	The program will display a warning dialog stating "Please note 
that the install process completely overwrites the files of an existing 
view."  This is important if you are installing a view created by an 
earlier version of VPFVIEW.  It is best to make a copy of the older view 
and install the copy to version 2.1.

	The program then will display the standard open file dialog.  Using 
the mouse, you may navigate through your file system to locate the view to 
install by its ENV file.  Views are denoted by a percent (%) symbol as 
the last character in the view directory name.

	After the view is selected for installation, the software parses 
its ENV file to determine the names of the database(s) contained in the 
view.  At that point, the view configuration dialog is displayed.  It 
contains a list of the names of the databases in your view.  An 
asterisk precedes the names of those databases which have not yet been 
located on your platform.  You update the path to those databases by 
double-clicking on a database name or selecting a name and pressing the 
"Modify Database Path" button below the list.  When you update a 
database path, the software displays the standard open file dialog from 
which you must locate the DHT (Database Header Table) or LAT (Library 
Attribute Table) for that particular database.  Please be warned that 
if you select a different database, the view will be corrupted, and 
VPFVIEW will refuse to load it.  When you update a database path, the 
asterisk before its name will be removed.

	When you are finished updating the paths to all databases in your 
view, press the install button.  The software will display a standard 
open file dialog prompting you to locate a symbology set to use for the 
view.  Typically, the symbology set is located in a directory named 
"symbols" which resides in the same directory as the executable 
software.  To select the symbology set, you must choose one of the 
following symbology files from that directory: AREAS.SYM, LINES.SYM, 
MARKERS.SYM or TEXT.SYM.  After you have selected a symbology set, the 
software will update the view format with your new information.  
VPFVIEW will prompt you to load the view.

	When it is finished loading, ensure the Zoom/Pan is set in the 
Library Reference window and start selecting the Themes/Features you 
wish to view from the Feature Selection Window.
