A. 1. a.(1)(a) i) a) 1. 1. a.(1)(a) i) a) 1., OVERVIEW OF THE SKELETAL STREET NETWORK FILE (# _____________________________________________________________________________  X , 1.1X44Description (#4 , Skeletal Street Network Files (SSNFs) are "thinnedout" street network files containing major roads and railways only (with street names but no address ranges). To define "major" streets, features forming census tract (CT) boundaries were used as a starting point. Where a street is identified as a CT boundary, effort was made to include its nonboundary extension for continuity. Shorelines or other water bodies are not included. Not all features forming CT boundaries were captured in the SSNFs.(# , Census tract boundaries were used to define "major" streets within an urban centre for three reasons:(# , ©,census tract boundaries tend to be major roads in a city;(# , ©,the automation of the "thinning" process was made easier; and(# , ©,this general concept was used to select major streets for the 1991 CMA/CA/CT reference maps.(# , The attribute information associated with the streets include the street name, the type, and its direction where the direction is used within the street name identification (such as First Ave East). A Railway is identified with its name, such as CNR, THB (for the Toronto, Hamilton and Buffalo railway), etc.(#  Xe , SSNFs are provided as a standard product in MapInfo format in the Lambert Conformal Conic projection. They can also be ordered in ARC/Info Export format. They are line files with no polygon topology.(# :&0*#'#'Ԍ X ԙ, 1.2X44Purpose(#4 , ,(# , The 1991 Skeletal Street Network Files contain a subset of streets and railways from the 1991 Street Network File. The SSNFs have been produced solely to provide some cartographic reference features when producing thematic maps with the CT Digital Cartographic Files (DCFs). The SSNFs do not contain shoreline features since shoreline is incorporated in the CT DCF.(# , The SSNFs exist for areas covered by Street Network Files in all 25 census metropolitan areas (CMAs) and the 14 census agglomerations (CAs) which are included in the census tract program. The SSNFs are provided for users who do not require the detail of the Street Network Files from which they were derived.(# :&0*#'#'Ԍ_____________________________________________________________________________  2. DATA QUALITY STATEMENT _____________________________________________________________________________ , The Skeletal Street Network Files were derived from the 1991 Street Network Files and the  Xv 1991 CT Digital Boundary Files. For a complete description of the SNF, refer to the 1991  Xa Street Network File User Guide, and the 1991 Digital Boundary File User Guide for the Digital Boundary File description.(#  X  , 2.1X44Lineage (#4  V , Lineage includes descriptions of the source material from which the data were derived and the methods of derivation, including the dates of the source material and all transformations  V involved in producing the final digital files or map products.(# , Source Material(# , The SSNFs were derived from the 1991 Street Network Files and the 1991 CT Digital Boundary Files as stated earlier. Refer to their respective user guides for a complete description of the lineage of those files.(# , Method of Derivation(# , The process of "thinning out" SNFs to create the SSNFs began by identifying those streets which were also CT boundaries by the following automated process:(# , Working in an ARC/Info Version 6.0 environment, the CT Digital Boundary Files were overlaid on the 1991 SNFs in order to "flag" those arcs which formed a CT boundary. Since the CT DBFs were constructed using SNF features, a good match was ensured.(# , Using attribute information tables in ARC/I  bK nfo  bK , the arcs comprising portions of streets identified in the overlay process were identified by STREET NAME (e.g. First) and TYPE (e.g. Ave). These attributes were used to ensure the complete street was retrieved, and not just the portion of each street which constituted a CT boundary. This process retrieved all streets in the CMA or CA with the same STREET NAME and TYPE, thus some "non" CT boundary streets are included in the SSNF.(# , In some cases, particularly in the larger urban centres, this process created a number of small unattached line segments (representing short streets or even highway ramps which have the same name as another street or ramp used elsewhere as a CT boundary within (# U%0*#'#'Ԍ X ԙ, 2.1 Lineage cont'd (# , the CMA or CA). Every attempt was made to interactively remove these segments, though some may still remain in the files.(#  X , Conversion to MapInfo(# , The MapInfo module ARCLINK was used to convert the resulting ARC/Info coverages into MapInfo format.(#  X  , 2.2X44Positional Accuracy (#4  V , Positional accuracy is the difference between the "true" position of a feature in the real world and "estimated" position stored in the digital file.(#  , Positional accuracy depends on the quality of the source material used and the processes used to create the files (ie. manual drafting, digitizing etc.). No numerical measurements of positional accuracy have been made. SSNFs are designed to provide reference to the locations of the CT cartographic boundaries, and the line features in the SSNFs match the boundaries precisely.(#  X  , 2.3X44Attribute Accuracy (#4  V , Attribute accuracy refers to the accuracy of the nonpositional information contained in the digital file.(#  , The attribute information contained in the file includes the feature NAME, TYPE and DIRECTION. Approximately 35 features within each of six of the 39 SSNFs were checked to ensure that the attribute information was transferred correctly from the corresponding Street Network Files. No errors were found.(# , Note that the feature names as provided in the SSNFs may not match those precisely as depicted on the CMA/CA/CT Reference Maps. In some cases, alternate names are used (e.g. Road 30 is shown on the map, but called Innes Rd in the SSNF. Both names were shown on a street map of the same area).(# , A few line segments in a SSNF may not have a name identified for them (For example, one such record in a total of 1535 records in the Halifax SSNF; three in 3699 records in the Hamilton SSNF less than 0.1%). These blank records have no impact on the use for which the SSNFs were intended.(# :&0*#'#'Ԍ X , 2.4 Logical Consistency (#  V , Logical consistency describes the fidelity of relationships encoded in the data structure of the digital spatial data (ie. how well elements of the data structure follow the rules imposed on  V them).(# , Some small unattached line segments may exist in the SSNFs as a result of the selection process from the SNF source files. These should have no impact on their use as a referential underlay for the CT DCFs for which the files were intended.(#  X  , 2.5X44Completeness (#4  V , Completeness expresses the degree to which the geographic entities (features) are captured according to the data capture specifications. It also contains information about selection  V criteria, definitions used and other relevant mapping rules.(# , No verification was done to ensure that all streets that formed CT boundaries were included in the SSNFs since 100% completeness was not a rigid requirement for the purpose of these files.(# , SSNFs do not exist for areas within the tracted CMA/CA not covered by Street Network Files.(# , (#  X  , 2.6X44Other Considerations (#4 , The SSNF will provide some context to the CT Digital Cartographic boundaries, in terms of street location, on a thematic map. Because CTs represent neighbourhoods, the bounding streets tend to represent major or well known streets within any given city. These are meant to allow users to "orient" themselves when viewing a thematic map.(# , The SSNF should not be used either to locate a street of interest (it may not be there), or as a definitive guide to major streets in a city (major streets are not always a CT boundary).(# , (# :&0*#'#'Ԍ X  _____________________________________________________________________________   X 3., TECHNICAL SPECIFICATIONS (MapInfo)(# _____________________________________________________________________________  X , In MapInfo, SSNFs are line files (as opposed to digital boundary files which are polygon files).(# , Attribute information associated with each line segment:(# , ,NAME: A twenty character code containing the given name of the feature.(# , ,TYPE: A two character item used for street identification when the street is a single or multiple lane street. The TYPE is a unilingual abbreviation such as RD (Road), BV (Boulevard), HY (Highway), LI (Line), CH (Chemin), RL (Ruelle), AV (Avenue).(# , ,DIRECTION: A two character code identifying the direction of the feature. The feature direction is not to be mistaken as being the geographic direction of a feature, but the direction used within the feature's identification. In most cases, this field is blank.(#  X4 , The MapInfo Table Structure is:(# , ,NAME , Character(20)hh#X(indexed(# , ,TYPEX` ` , , Character(2)(# , ,DIRECTION Character(2)(# :&0*#'#'Ԍ X  _____________________________________________________________________________ 4.
