	The Canadian Vegetation and Land Cover - generalized version
==============================================================================

This data set has been prepared from the original vector data set
produced from the raster 1km pixel classified image.  The classified
image was the result of cooperative work between the National Atlas
Information System (NAIS) group of NRCan, the Manitoba Remote Sensing
Centre and Forestry Canada. Other contributions in that work came from
the GIS Division and the Canada Centre for Remote Sensing.

The original vector data set was generalized using the Arc/Info software.
The method used was simple:  all polygons with area less than 50 sq km
were eliminated, except for those representing built-up areas.  No attempt
was made to smooth lines. However all pseudo-nodes were removed. 

The coastline is that obtained from the vectorization process.  No attempt
was made to substitute the lines representing the coastline with any other
available data set.  It is felt, by comparing with the 1:2million coastline
from the National Atlas data set, that the lines present in the generalized
data set are adequate for a 7.5million scale representation.

N.B.
This data set is meant to be used at a minimal scale of 7.5M. and is best
for cartographic-type applications or world-scale applications.


DESCRIPTION OF COVERAGES
========================

The Canadian land is divided in two portions (due to limitation in
the Arc/Info software - 10000 arcs/polygon). "vegeast", "vegwest".
The border between Manitoba and Ontario is used as the division line.
However, connection between the two portions can be obtained since
all nodes are snapped between the two portions.

The two covers contain both line and polygon topology.

The arc/info .AAT file contains an attribute called CODE.  The value
is 0 for all lines except those lines representing the east-west 
boundary which have a value of -1.

The arc/info .PAT file contains an attribute called F_CODE.  The value
ranges from 1 to 11, representing a vegetation-land cover type.

The arc/info look-up table VEG_CODE.LUT contains three items:
F_CODE, SYMBOL (for display purposes - can be changed by the user) and

DESCRIPTION OF ARC/INFO COVERAGES:

VEGEAST:  2220 polygons, 4532 arcs
VEGWEST:  5186 polygons, 10896 arcs

ICE:	   140 polygons (.... no arc topology) - this cover is only given
for reference .  It has not been processed as completely as the other in 
order to remove small polygons (< 50 sq km).  The polygons carry the F_CODE
attribute where polygons with f_code value equals to 13 represent polar ice,
those with values of 3 represent inclosed water and that with values of 0
and no labels are those polygons where land occurs, except for the oceanic
water body.
