About the CD-ROM
----------------
This CD-ROM contains several sets of digital data files
(see \CANADA\DOC\ENGLISH\FILES.TXT for formats).  Although the
digital data was prepared with Arc/Info, it can also be accessed
by several other operating systems and GIS packages.

Directory Structure
-------------------
The CD-ROM is divided into the following primary directories:
  \CANADA
	\DOC		- English & French documentation

	\COVERS		- Arc/Info 7 workspaces
	\E00		- Arc/Info Interchange 'Export' files
	\SHP		- Arc/Info 'shape' files
	\SHPGEO		- Arc/Info 'shape' files (geographic)

	\SURVIEW	- Microsoft Windows viewing software
			  (for 'shape' files)
	\UTIL		- ANSI-DOS conversion utility
		
Documentation
-------------
All documentation is provided in 3 text formats and in 2 
languages:
   \CANADA\DOC\ENGLISH   - PC   text files (.TXT)
                         - Unix text files (.UNX)
   \CANADA\DOC\FRANCAIS  - PC   text files (.TXT) 
                         - Unix text files (.UNX)
   \CANADA\DOC\HTML      - HTML text files (.HTM) 
                           (English, French)

Documentation begins on HTML page INTRO_E.HTM (English) or 
INTRO_F.HTM (French) or on the corresponding INTRO.* text
files in the ...\ENGLISH and ...\FRANCAIS directories.

Note that the Internet Explorer, provided with pre-installed
versions of Windows 95, is effectively obsolete and can not
display HTML tables correctly. Use a newer version of the
Web browser of your choice.

Character Set
-------------
All PC (.TXT) and Unix (.UNX) files contain ANSI accented 
characters: PC users should use Windows applications to view 
these files.

ESRI Interchange Format files (*.E00, single precision) are
provided in PC format and contain ANSI characters.  For use on
Unix, use the Unix "dos2unix -ascii" command to convert to Unix
text format and preserve the ANSI characters.

.DBF files also contain ANSI characters: you may need to use the
AnsiConv utility (in \CANADA\UTIL) to convert to a DOS character
set for use with some utilities.  See \CANADA\DOC\README.TXT

SurView (Microsoft® Windows TM)
--------------------------------
A limited runtime version of SurView (a viewing application
developed by the GSC to display geophysical, geological, and
geochemical data) is provided on this CD-ROM in the
\CANADA\SURVIEW directory. SurView can display and print the
Arc/Info .SHP files in the \CANADA\SHP directory.

Read the \CANADA\DOC\ENGLISH\SURVIEW1.WRI file for an overview 
of the installation and operation of SurView. Read the
\CANADA\DOC\ENGLISH\SURVIEW2.WRI file for an overview of the
.SHP files and the SurView-specific files that allow them to be
displayed.
        
Quick Start (Microsoft® Windows TM)
------------------------------------
This CD-ROM is a Microsoft® Windows TM 95/NT4 'Auto Play' 
CD-ROM, launching \INTRO.EXE when inserted (other Windows 
users can launch \INTRO.EXE manually).  \INTRO.EXE provides 
an introduction to the CD-ROM and can launch WINTOUR.HLP. 
to provide a quick tour of the \CANADA\SHP\... 'shape' files. 
\WINTOUR.HLP contains hypertext links to launch SurView 
directly from the CD-ROM (no installation required) to view 
these files.

Arc/Info (Ver. 7.03) on Unix (Solaris 2.4)
------------------------------------------
The Arc/Info coverages are located in the \CANADA\COVERS
directory.

Read the \CANADA\DOC\ENGLISH\DATABASE.TXT file for complete 
descriptions of the Arc/Info coverages.

There is no Unix software supplied on this CD-ROM.

Arc/Info on other platforms 
---------------------------
The Arc/Info coverages have been exported into ANSI Interchange
Format (*.E00, single precision) files located in the \CANADA\E00
directory. These can be imported into Arc/Info on non-Unix 
systems.

Other (Microsoft® Windows TM )/DOS-based GIS packages
----------------------------------------------------
The *.E00 files in \CANADA\E00 can be imported into several other
GIS packages that import the .E00 format, including ArcView and
MapInfo for Microsoft® Windows TM

The Arc/Info coverages have been also exported into Arc/Info
'shape' (*.SHP) files, designed to be directly viewable by
ArcView 2.
