                            INTRODUCTION

	The program IMGVIEW is a simple program for viewing image data with 
options for plotting vector and text information on the images.  This program 
allows the user to display any one of a number of images of data for the conterminous 
United States and to plot selected vector and text data on the images.  IMGVIEW is 
designed to be compatible with the data published by Phillips, Duval, and Ambroziak (1993)

                            INSTALLATION

This program designed to run under Microsoft Windows 3.1 or higher and in order to 
successfully install IMGVIEW, you need to be familiar with the Windows operating system 
for personal computers.  In order to use this program, you will need to check for the 
existence of the library named MFC250D.DLL under the C:\WINDOWS\SYSTEM directory.  If 
this library does not exist, you need to do the following:

	1.	return to the MS-DOS prompt,
	2.	change the current directory to C:\WINDOWS\SYSTEM using the DOS command 
                "CD C:\WINDOWS\SYSTEM,
	3.	run the command "A:\MFC250D where "A" is assumed to be the
                drive letter for your floppy disk drive.

	This will place a copy of the 1.8-Mb file MFC250D.DLL in the C:\WINDOWS\SYSTEM 
directory.  I recommend that you then do the following:

	1.	if the directory C:\USGS does not exist, create it using the DOS command 
                "MKDIR C:\USGS",
	2.	change the current directory to C:\USGS using the DOS command "CD C:\USGS",
	3.	run the command "A:\IMGVIEW" where "A" is assumed to be the 
                drive letter for your floppy disk drive.

	This will place copies of the files IMGVIEW.EXE and IMGVIEW.HLP in the 
C:\USGS directory.

	If you are using Windows 3.x, I recommend that you do the following:

	If the program group USGS does not exist, then

	1.	select the File option of the main menu of Program Manager,
	2.	select the New option from the File drop-down menu,
	3.	select Program Group and click on OK,
	4.	select the Description text box and enter "USGS" and click on OK,

	Add the IMGVIEW program to the program group.

	1.	make sure the program group USGS is active by clicking within the 
                program group window,
	2.	select the File option of the main menu of Program Manager,
	3.	select the New option from the File drop-down menu,
	4.	select Program Item and click on OK,
	5.	select the Description text box and enter "IMGVIEW",
	6.	select the Command Line text box and enter "C:\USGS\IMGVIEW.EXE",
	7.	select the Working Directory text box and enter an appropriate directory 
                (e.g. C:\NUREDATA) and click on OK.

	Following the above steps will create a program group named USGS and will 
install IMGVIEW as a member of the program group.  You can then run IMGVIEW by double 
clicking on the IMGVIEW icon.  For information on using IMGVIEW, you should access the 
help file provided with the program.

	If you are using Windows 95, we recommend that you do the following:

	1.	using Explorer, navigate to the C:\WINDOWS\Start Menu\Programs directory,
	2.	select the File option of the main menu of Explorer,
	3.	select the New option from the drop-down menu of the File option,
	4.	select the Folder option of the drop-down menu of the New option,
	5.	edit the name of the folder and enter "U.S. Geological Survey"

	This results in the creation of a new folder named "U.S. Geological Survey".  
To install the IMGVIEW program in the folder, do the following:

	1.	using Explorer, navigate to the directory
                    C:\WINDOWS\Start Menu\Programs\U.S. Geological Survey
	2.	select the File option of the main menu of Explorer,
	3.	select the New option from the drop-down menu of the File option,
	4.	select the Shortcut option of the drop-down menu of the New option,
	5.	select the Command line text box and enter "C:\USGS\IMGVIEW.EXE"

	This results in the creation of a shortcut to the IMGVIEW program.  If you 
want to be able to access the IMGVIEW help file directly, you can repeat the above 
steps and enter "C:\USGS\IMGVIEW.HLP" for the command line.  After you have completed 
the above, you can run the IMGVIEW program from the Start menu in the same manner as 
other programs.
