CANADA LAND INVENTORY LEVEL-II UTM DIGITAL DATA LAND CAPABILITY FOR RECREATION 1.0 Coverage Specifications Original Map Scale: 1:250,000 Resolution : originally .00024412 of a degree, which corresponds to approximately 25 meters Map Projection : Universal Transverse Mercator (UTM) Datum : NAD27 Spheroid : Clarke 1866 Units of Measure : meters 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. 3. Attribute Schema (Polygon Attribute Table - PAT.DBF) a) Standard ArcInfo Polygon Attribute Table (PAT) variables: AREA Num 13,6 Area, in square meters PERIMETER Num 13,6 Perimeter, in meters COVER_# Num 11,0 Standard ArcInfo Polygon Number COVER_ID Num 11,0 Standard ArcInfo User ID b) Computed User Variables: Prime_REC Num 3,0 The percentage (base 100) of the polygon which is considered as prime recreation lands, i.e. the percentage of the polygon which is in classes 1-3. Marge_REC Num 3,0 The percentage (base 100) of the polygon which is considered as marginal recreation lands, i.e. the percentage of the polygon which is in classes 4-5. c) Component Table Extension Pointer CMP_Index Char 10 Unique polygon identification code for the secondary Component Table (CMP.DBF). d) Original Digital Data Classification: Class_A Char 1 The primary and/or dominant CLI class Percent_A Char 1 The proportion (% base 10) of the polygon in Class_A (blank = 100%) Features_A Char 3 The recreation feature(S) for the proportion of the polygon in Class_A Class_B Char 1 The secondary CLI class Percent_B Char 1 The proportion (% base 10) of the polygon in Class_B (blank = 0%) Features_B Char 3 The recreation feature(s) for the proportion of the polygon in Class_B Class_C Char 1 The tertiary CLI class Percent_C Char 1 The proportion (% base 10) of the polygon in Class_C (blank = 0%) Features_C Char 3 The recreation feature(s) for the proportion of the polygon in Class_C Note(s): i) To classify the data in a manner similar to the way the CLI paper maps were printed,use field Class_A. ii) For a more meaningful interpretation of recreational land potential, use fields Prime_REC and Marge_REC, or a combination of both with an incremental color palette. iii) For the location of specific land unit types, use a combination of classes and features. 4.

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.
