Geological Map of Canada - Map 1860A Files, directories, and Formats
Files, Directories, and Formats
Overview
The directory structure of this CD-ROM has been designed to facilitate
simple and logical access to the data.
This CD-ROM conforms to the ISO-9660 system-independent standard. An
ISO-9660-formatted CD-ROM works identically on a PC, Macintosh, or Unix
workstation. The directory and file structure of the CD-ROM can be viewed as if
it were a conventional hard disk. Although the file structure is system
independent, the user must still deal with differences in the way different
operating systems format files, in particular text files. Text files
are provided in PC and Unix compatible formats.
Compact discs are a cost effective way of distributing large quantities of
data but do have some limitations. Data transfer rates of CD-ROMs are comparable
to hard disks but access times are much slower. The slow access time can have
negative implications for applications that require concurrent querying of
several files. The speed of access to the data coverages can be greatly
improved by copying them to the hard disk.
A summary of all files and directories on this CD-ROM appears at the end
of this section.
The 'Root' Directory
The top-level \ ('root') directory of the CD-ROM contains the following files:

A. Documentation
The \CANADA\DOC directory contains three subdirectories: \ENGLISH,
\FRANCAIS, and \HTML, each of which contains a complete copy of all of the
documentation for the CD-ROM.
Each English or French document is provided in three formats, identified by
the filename extension:
- *.TXT - PC ANSI text format
- *.UNX - Unix ANSI (ISO) text format
- *.HTM - Hyper Text Markup Language (HTML) for Web browsers
The SurView-specific documentation (SURVIEW1.WRI, SURVIEW2.WRI) is provided
only in Microsoft Windows .WRI format, since SurView is a Microsoft Windows
application.
In addition, the *.HTM files are accompanied by a selection of *.GIF
image files.

B. Data
Each of the primary data directories (\COVERS, \E00, \SHP, and \SHPGEO)
contains ten subdirectories: one for each of the eight compilation blocks
(by author) and two for all of Canada.

C. Software
There is no Unix software on this CD-ROM. However, the
\CANADA\COVERS\UTIL directory contains a sample Arc/Info AML script,
lineset, markerset, textset, and shadesets for drawing the Geological
Map of Canada by 'unit code'. For further information, read the
\CANADA\COVERS\UTIL\README.UNX file.
SurView
The \CANADA\SURVIEW directory contains the SurView application for Microsoft
Windows (any version). SurView was developed at the Geological Survey of
Canada as a viewing application for geophysical, geochemical and geological
data. It is not a complete GIS package, but it does allow the user to view,
zoom/pan, query, change colours and print on any Microsoft Windows platform.
The SurView files are:

SurView can be run directly from the CD-ROM. For full instructions on the
installation and use of SurView, read the SURVIEW1.WRI and SURVIEW2.WRI
documentation in \CANADA\DOC\ENGLISH.
AnsiConv
The \CANADA\UTIL directory contains the ANSICONV.EXE utility for Microsoft
Windows (developed at the Geological Survey of Canada) for converting .DBF
files between ANSI (Windows, Unix) and DOS character sets to allow the files
to be used with most spreadsheets and database applications.
This utility is only required if you intend to use a spreadsheet or
database application to modify the .DBF files provided on this CD-ROM.
For further information, read the \CANADA\UTIL\README.TXT file.
File formats
Arc/Info
Each of the ten subdirectories in the \CANADA\COVERS directory contains a
complete Arc/Info 7 workspace. All Arc/Info coverages are single precision.
It should be possible to access all of the coverages directly from the
CD-ROM.
There are nine workspaces of geological data (one for each compilation block
and one for all of Canada). Topographic bases for all compilation
blocks are located in the \CANADA\COVERS\BAS subdirectory.
Interchange file formats
Two interchange file formats are used to ensure compatibility of
the data with a wide range of GIS systems:
Interchange format
Filename extension |
Description |
.E00 |
Arc/Info 'Export' (PC ANSI text) |
.SHP |
Arc/Info 'Shape' (binary) |
Each of the \SHP, \SHPGEO, and \E00 subdirectories contains a set
of directories and files which correspond to the Arc/Info coverages.
A. *.E00 (\CANADA\E00\...)
These are Arc/Info interchange format files in PC ANSI format. In order
to use these files on Unix systems, first they must be converted to Unix
text format with the Unix 'dos2unix -ascii' command (see your Unix
documentation). You must use the '-ascii' option.
All .E00 files contain single precision equivalents of the Arc/Info
single precision coverages. All versions of Arc/Info on all platforms
should be able to import these .E00 files. They were exported from Arc/Info
using the 'none' option (not compressed). Several other GIS packages can
also import these files: consult the documentation for the GIS package
that you are using.
Each of the eight compilation block subdirectories contains both geological
and topographical data.
B. *.SHP (\CANADA\SHP\...)
Arc/Info *.SHP 'shape' files were created by exporting each coverage using
the Arc/Info 7 'arcshape' command. Although the coverages from which the
.SHP files were created are all single precision, .SHP files always
contain double precision data (by definition), requiring twice as much
disk space as necessary.
The .SHP files contain nontopological (whole polygon) representations of
the Arc/Info coverages in (\CANADA\COVERS). Each coverage is represented by
three files (.SHP, .SHX, .DBF) created by the 'arcshape' command. These shape
files can be viewed directly from the CD-ROM (no import required) by both
Arcview 2 and SurView.
Each of the eight compilation block subdirectories contains both geological
and topographic data.
The \CANADA\SHP directory contains an additional \ZLUT directory containing
.DBF lookup tables used by SurView for displaying the .SHP files. These .DBF
files are referenced by the *.ASX files which encapsulate each set of
.SHP/.SHX/.DBF files.
For more information on SurView, (including more information on .SHP files)
please read the SurView documentation in \CANADA\DOC\ENGLISH. See the
description of SURVIEW1.WRI and SURVIEW2.WRI above.
*.SHP (\CANADA\SHPGEO\...)
The \CANADA\SHP files contain co-ordinates for the Lambert Conformal Conic
projection. Neither ArcView nor SurView can re-project these files to
another projection. Therefore, the entire \CANADA\SHPGEO directory tree
contains a duplicate of every file in the \CANADA\SHP directory tree, but
containing geographic (longitude, latitude) co-ordinates instead of Lambert.
All *.SHP, *.SHX, and *.DBF files in this directory tree have a 'G' suffix
to indicate that the file contains geographic co-ordinates.
The geographic *.SHP files in \CANADA\SHPGEO can be viewed and re-projected
as required by both ArcView and SurView. You can use these files instead
of the Lambert files if you want to use the Geological Map of Canada as a
background for other geophysical, geochemical, or geological data that is
only available in a non-Lambert projection.
For example:
\CANADA\SHP\COR (Lambert projection) |
\CANADA\SHPGEO\COR (geographic) |
ROXCOR.SHP |
ROXCORG.SHP |
ROXCOR.SHX |
ROXCORG.SHX |
ROXCOR.DBF |
