2. CLI Level II UTM Digital Data Enhancements

  CLI Level II UTM digital data have undergone the following
  transformation from their original Level I representation:

  a) The data are fully integrated with the corresponding CLI
     shoreline layer, i.e. the CLI polygons are no longer
     extended into the water.

  b) The data are projected to UTM.

  c) Additional computed variables are included to facilitate
     user interpretation of the data.

  d) A secondary attribute Component Table (CMP.DBF) is
     included and compatible with the ArcView Component Table
     Extension developed by Agriculture Canada.

  e) The class modifier code, which was inconsistently coded
     in the original digital version of the data, was
     eliminated.

  Note(s):

   i) The CLI shoreline is based on older edition
      topographic base maps, which may no longer be
      current.

  ii) Strict adherence to the 6-degree UTM zone convention
      has been made during the projection of the data to
      UTM, i.e.:

       Zone 22 - all maps East of 54 W. Longitude
       Zone 21 - all maps between 54 and 60 W. Longitude
       Zone 20 - all maps between 60 and 66 W. Longitude
       Zone 19 - all maps between 66 and 72 W. Longitude
       Zone 18 - all maps between 72 and 78 W. Longitude
       Zone 17 - all maps between 78 and 84 W. Longitude
       Zone 16 - all maps between 84 and 90 W. Longitude
       Zone 15 - all maps between 90 and 96 W. Longitude
       Zone 14 - all maps between 96 and 102 W. Longitude
       Zone 13 - all maps between 102 and 108 W. Longitude
       Zone 12 - all maps between 108 and 114 W. Longitude
       Zone 11 - all maps between 114 and 120 W. Longitude
       Zone 10 - all maps between 120 and 126 W. Longitude
       Zone 09 - all maps West of 126 W. Longitude

      DO NOT ATTEMPT TO PROCESS OR VIEW DATA ACROSS UTM
      ZONES.

 iii) In the process of integrating the CLI shoreline with
      these data, every attempt has been made to conserve
      the look and contents of the printed CLI maps. To
      this end, a restricted small area dissolve procedure
      has been applied to the overlay results.  We
      apologize if any of these small areas persists, or if
      small areas have been eliminated as a result of this
      procedure.

  iv) To reduce file sizes and the time for download, a mild
      coordinate reduction has been applied to the original
      lat/lon data before projection to UTM.

7. Narrative Description of CLI Classification

   Seven classes of land were differentiated on the basis of
   the intensity of outdoor recreational use, or the quantity
   of outdoor recreation, which may be generated and
   sustained per unit area of land per annum, under perfect
   market conditions.

   "Quantity" may be measured by visitor days, a visitor day
   being any reasonable portion of a 24 hour period during
   which an individual person uses a unit of land for
   recreation.

   "Perfect Market Conditions" implies uniform demand and
   accessibility for all areas, which means that location
   relative to population centers and to present access do
   not affect the classification.

   Intensive and dispersed activities were recognized.
   Intensive activities are those in which relatively large
   numbers of people may be accommodated per unit area, while
   dispersed activities are those which normally require a
   relatively larger area per person.

   Some important factors concerning the classification were:

    The purpose of the inventory was to provide a reliable
    assessment of the quality, quantity and distribution of
    the natural recreational resources within the settled
    parts of Canada.

    The inventory was of an essentially reconnaissance
    nature, based on interpretation of aerial photographs,
    field checks, and available records. The maps should be
    interpreted accordingly.

    The inventory classification was designed in accordance
    with present popular preferences in non-urban outdoor
    recreation.  Urban areas (generally over 1,000 population
    with permanent urban character), as well as some
    non-urban industrial areas, were not classified.

    Land was ranked according to its natural capability under
    existing conditions, whether in natural or modified
    state; but no assumptions were made concerning its
    capability given further major artificial modifications.

    Sound recreational land management and development
    practices were assumed for all areas in practical
    relation to the natural capability of each area.

    Water bodies were not directly classified.  Their
    recreational values accrue to the adjoining shoreland or
    land unit.

    Opportunities for recreation afforded by the presence in
    an area of wildlife and sport fish were indicated in
    instances where reliable information was available, but
    the ranking does not reflect the biological productivity
    of the area.  Wildlife capability is indicated in a
    companion series of maps.

8. CLI Recreation Class Descriptions

    CLASS 1 Lands in this class have very high capability for
            outdoor recreation.  Class 1 lands have natural
            capability to engender and sustain very high
            total annual use based on one or more
            recreational activities of an intensive nature.
            Class 1 land units should be able to generate and
            sustain a level of use comparable to that evident
            at an outstanding and large bathing beach or a
            nationally known ski slope.

    CLASS 2 Lands in this class have a high capability for
            outdoor recreation.  Class 2 lands have natural
            capability to engender and sustain high total
            annual use based on one or more recreational
            activities of an intensive nature.

    CLASS 3 Lands in this class have a moderately high
            capability for outdoor recreation. Class 3 lands
            have natural capability to engender and sustain
            moderately high total annual use based usually
            on intensive or moderately intensive activities.

    CLASS 4 Lands in this class have a moderate capability
            for outdoor recreation. Class 4 lands have
            natural capability to engender and sustain
            moderate total annual use based usually on
            dispersed activities.

    CLASS 5 Lands in this class have a moderately low
            capability for outdoor recreation. Class 5 lands
            have natural capability to engender and sustain
            moderately low total annual use based on
            dispersed activities.

    CLASS 6 Lands in this class have low capability for
            outdoor recreation. Class 6 lands lack the
            natural quality and significant features to
            rate higher, but have the natural capability to
            engender and sustain low total annual use based
            on dispersed activities.

    CLASS 7 Lands in this class have very low capability for
            outdoor recreation. Class 7 lands have
            practically no capability for any popular types
            of recreational activity, but there may be some
            capability for very specialized activities with
            recreational aspects, or they may simply provide
            open space.

9. CLI Recreation Feature Descriptions

   Subclasses indicate the kinds of features which provide
   opportunity for recreation.  They are, therefore, positive
   aspects of land and do not indicate limitations to use.
   Features may be omitted from a unit, either because of the
   imposed three-feature limit, or because their presence was
   unknown or unconfirmed.

   The degree to which these features are judged capable,
   collectively, of generating and sustaining use for
   recreation, determines the class. The sequence in which
   they are listed indicates the order of their significance.
   Subordinate features may be relatively insignificant and
   the class of a unit should not be interpreted to indicate
   the capability of a secondary or tertiary feature.

   The subclasses are:

   'A'  Land providing access to water affording opportunity
        for angling or viewing of sport fish.

   'B'  Shoreland capable of supporting family beach
        activities.

        In higher class units this will include family
        bathing. In classes 4 and 5, the activities may be
        confined to dry land due to cold water or other
        limitations.

   'C'  Land fronting on and providing direct access to
        waterways with significant capability for canoe
        tripping.

   'D'  Shoreland with deeper inshore water suitable for
        swimming or boat mooring or launching.

   'E'  Land with vegetation possessing recreational value.

   'F'	Waterfall or rapids.

   'G'	Significant glacier view or experience.

   'H'	Historic or pre-historic site.

   'J'  Area offering particular opportunities for gathering
        and collecting items of popular features.

   'L'  Interesting landform features other than rock
        formations.

   'M'  Frequent small water bodies or continuous streams
        occurring in upland areas.

   'N'  Land (usually shoreland) suited to family or other
        recreational lodging use.

   'O'  Land affording opportunity for viewing of upland
        wildlife.

   'P'  Areas exhibiting cultural landscape patterns of
        agricultural, industrial or social interest.

   'Q'  Areas exhibiting variety, in topography or land and
        water relationships, which enhances opportunities for
        general outdoor recreation such as hiking and nature
        study or for aesthetic appreciation of the area.

   'R'  Interesting rock formations.

   'S'  A combination of slopes, snow conditions and climate
        providing downhill skiing opportunities.

   'T'  Thermal springs.

   'U'  Shoreland fronting water accommodating yachting or
        deep water boat tripping.

   'V'  Vantage point or area which offers a superior view
        relative to the class of the unit(s) which contain
        it, or a corridor or other area which provides
        frequent viewing opportunities.

   'W'  Land affording opportunity for viewing of wetland
        wildlife.

   'X'  Miscellaneous features with recreational capability.

   'Y'  Shoreland providing access to water suitable for
        popular forms of family boating.

   'Z'  Areas exhibiting major, permanent, non-urban,
        man-made structures of recreational interest.
