Introduction + ____________ 0 CARTLIB is a cartographic library of computer files of standard Census boundaries. Each CARTLIB file includes geostatistical area boundaries and major hydrographic features. CARTLIB files are ideal for computer assisted thematic mapping to support research, such as demographic and socio-economic studies, or market analysis. CARTLIB files can be used with the 1986 Census of Population and Housing data from the User Summary Tape (UST) series, or other data available at subprovincial standard census geographic area levels. Geostatistical areas in CARTLIB are associated with the Standard Geographic Classification (SGC) codes that are used to reference all census data available from Statistics Canada. Note: CARTLIB files are intended for thematic mapping purposes only. The positional accuracy may not support other uses, such as cadastral mapping or data retrieval. 0 II. The Census Tract level CARTLIB files Census tracts are small permanent census areas established in large urban areas (population over 50,000) with the help of local social scientists and planners. There are about 4,000 people per CT. Source maps: 1:50,000 & 1:250,000 scale NTS base maps. Projection: UTM (except Calgary and Edmonton which are Lambert conic conformal with 2 standard parallels at 49N and 77N. Coordinate system: meters. CARTLIB files are available, in the form of character GIMMS Raw Segment files, for all 25 census metropolitan areas (CMAs). There is one segment file for each CMA: CMA # of CTs Datasetname (DSN) Calgary 143 CT.CALGARY.86 Chicoutimi-Jonquiere 32 CT.CHICOUTM.86 Edmonton 187 CT.EDMONTON.86 Halifax 74 CT.HALIFAX.86 Hamilton 151 CT.HAMILTON.86 Kitchener 77 CT.KITCHENR.86 London 88 CT.LONDON.86 Montreal 716 CT.MONTREAL.86 Oshawa 44 CT.OSHAWA.86 Ottawa-Hull 192 CT.OTTHULL.86 Quebec City 138 CT.QUEBEC.86 Regina 47 CT.REGINA.86 Saskatoon 44 CT.SASKATN.86 Sherbrooke 31 CT.SHERBRK.86 St. Catharines-Niagara 83 CT.STCATHNG.86 St. John 42 CT.STJOHN.86 St. John's 39 CT.STJOHNS.86 1 Sudbury 38 CT.SUDBURY.86 Thunder Bay 30 CT.THUNDERB.86 Toronto 731 CT.TORONTO.86 Trois Rivieres 31 CT.TROISRIV.86 Vancouver 274 CT.VANCOUVR.86 Victoria 59 CT.VICTORIA.86 Windsor 58 CT.WINDSOR.86 Winnipeg 148 CT.WINNIPEG.86 In the GIMMS Raw Segment files, the boundary of each census tract is delimited by one or more segments which together make up a polygon. The segments that make up a polygon are defined by a series of x,y coordinate pairs. In a few cases, areas may enclose bodies of water or enclaves (other geographic areas). These internal boundaries or 'holes' are described by internal segments of polygons. At the beginning of each census tract level segment file are 5 header records, including file title, date, type, and projection information, where known. The remainder of each file consists of data records. There are two types of data record in the CARTLIB segment files: (1) the first is a single identifier record, consisting of the pair of census tract codes (4-digit) of the adjacent census tracts which the segment of boundary divides; each census tract code is preceded by the characters 'CT'. (2) the second type of data record consists of a string of pairs of UTM (Universal Transverse Mercator) x,y coordinates, usually listed in clockwise sequence. As many x,y coordinate pairs are included to describe the segment until the next vertex or the pair of adjacent census tracts changes. The vertex that ends one segment is repeated at the beginning of the next segment, until the polygon is closed. The segment record consists of as many physical records (86 characters per record) as are needed to describe the full segment. The minimum number of x,y pairs is two. X-coordinates have format I6; Y-coordinates have format I7. A slash ('/') signals the end of a segment record. The next physical record will be a new identifier record, or the end of the file. The census tracts were digitized at 1:50,000. The tracts were then enhanced to include shoreline and major rivers and lakes. These geographic features were digitized at scales ranging from 1:50,000 to 1:250,000. The coordinate system employed for 23 centres is the Universal Transverse Mercator (UTM). The remaining 2 centres (Calgary and Edmonton) were converted from UTM to Lambert Conic Conformal coordinates using a projection transformation program; this was necessary to facilitate computer mapping since these centres are located in two UTM zones. 1 Detailed CT reference maps can be found in the 1986 census bulletins listed in Appendix C. For a correspondence list linking the census tract numbers with other geographic area codes and names, see: Enumeration area reference list : census tracts (cat. no. + _______________________________________________ 99-913). 0 Similar information in machine-readable form at the enumeration area level is contained in the 1986 Geography Tape File. III. The Census Subdivision level CARTLIB file Census subdivisions (CSDs) include municipalities or their equivalents, Indian Resreves and settlements, and unorganized territories. The boundaries represent Statistics Canada's official limits, and therefore do not follow all shoreline features (e.g. small islands belonging to the same CSD may be coded as one polygon). Source maps: 1:50,000 & 1:250,000, 1:1,000,000 and 1:4,000,000 scale NTS base maps. Projection: Lambert conic conformal with 2 standard parallels at 49N and 77N. Coordinate system: meters. The Census Subdivision level CARTLIB file (dsn=CND.CSD.86) describes the 6009 census subdivisions defined in 1986.

The segments that make up a polygon are defined by a series of x,y coordinate pairs. Areas may enclose bodies of water or enclaves (other geographic areas). These internal boundaries or 'holes' are described by internal segments of polygons. At the beginning of the census subdivision segment file are 5 header records, including a title, date, type, and projection information, where known. The remainder of the file consists of data records. 1 There are two types of data records in the GIMMS Raw Segment file: (1) the first record is a single identifier record, consisting of the pair of census subdivision codes (7-digit) of the adjacent census subdivisions which the boundary segment divides; each code is preceded by the character 'A'. Census subdivision codes consist of (province code (2 digits) + census division code (2 digits) + census subdivision code (3 digits)). (2) the second type of data record consists of a string of pairs of Lambert Conic Conformal x,y coordinates (see copy of Lambert parameters in Appendix A), usually listed in clockwise sequence. As many x,y coordinate pairs are included to describe the segment until the next vertex or the pair of adjacent census subdivisions changes. The vertex that ends one segment is repeated at the beginning of the next segment, until the polygon is closed. The segment record consists of as many physical records (86 characters per record) as are needed to describe the full segment. The minimum number of x,y pairs is two. X-coordinates have format I6; Y-coordinates have format I7. A slash ('/') signals the end of a segment record. The next physical record will be a new identifier record, or the end of the file. The census subdivision records were digitized at 1:50,000. The tracts were then enhanced to include shoreline and major rivers and lakes. These geographic features were digitized at scales ranging from 1:50,000 to 1:4,000,000 (in the far north, i.e. the Arctic archipelago).
