Abstract:
The National Road Network, Canada, Level 1 (NRNC1) focuses on providing a quality geometric description and a set of basic attributes of Canadian road phenomena. The first release of the NRNC1 product will not include Resource/Recreation roads. Geographic Data Files (GDF) V4 from ISO/TC 204 were used as a guideline for this model. The NRNC1 product strives to comply, to the degree possible, with GDF vocabulary (Class names, attribute names, and definitions). The modeling work of the NRNC1 was primarily based on Linear Reference System (LRS) concepts. This approach allows the management of geometric representation separately from attribute information (referred to as event in LRS). Unique Identifiers are associated with each geometric and event object. These IDs (called National Identifiers - NIDs) will lead to more efficient management of updates between data producers and data users. The Centre for Topographic Information - Sherbrooke (CTIS), part of Natural Resources Canada (NRCan), produced the first version of the NRNC1. CTIS continues to pursue its goal of capturing and managing NRNC1 data within a network of partners. These partner organizations are selected for their specific interests or for their ease in offering adequate, up-to-date representations of road phenomena. These data must be the product of a homogenous, standardized view of the entire Canadian landmass. The data model can (and must) extend beyond the smallest common denominator obtained with the partners. The model must therefore contain two levels of information: mandatory data and optional data. Data homogeneity will thereby be ensured by a minimum set of data. Beyond the minimum level, the model serves as a target for all partners. Minimum content has been defined for attributive and geometric data. The NRNC1 data will serve as a foundation for several applications. The available output file format for the product are: GML (Geography Markup Language) in ASCII and SHAPE (ESRI - TM).
Purpose:
The NRNC1 data will serve as a foundation for several applications. This common infrastructure should facilitate data integration with supplementary data.

Data_Quality_Information:
Attribute_Accuracy:
Attribute_Accuracy_Report:
NRNC1 data were acquired from several sources (GPS, provincial data, municipal data, and NTDB data, in some cases). Two methods were used to validate the data.. When available, orthophotos and orthoimages were used to validate the NRNC1 data. Various other sources made available by different organizations were also used. Finally, on-site field visits were carried out in strategic areas. Regardless of the method of validation used, all errors detected were flagged and resubmitted with the proper corrections.
Logical_Consistency_Report:
The logical consistency of the NRNC1 data can be evaluated on several aspects.

- NRNC1 data are seamless and not segmented at any theoretical tile boundaries.

- NRNC1 data were acquired, as much as possible, from data closest to the source (such as municipalities). When municipal data are used, the same geometry is used for all 3 levels of government: federal, provincial, and municipal.

Completeness_Report:
The NRNC1 data model catalogues have defined two types of information: minimal requirements (mandatory) and expanded (optional) attributes, which includes recreational roads and addresses. The minimal requirements (core part) for the NRNC1 will consist of homogeneous content for the country. Expanded attributive information (geometric and attributive) for some provinces may be found at the source level. Mechanisms are proposed in National Vector Data ¿ External Databases. to facilitate the integration of geometric and attributive data with NRNC1 data.
Positional_Accuracy:
Horizontal_Positional_Accuracy:
Horizontal_Positional_Accuracy_Report:
The NRNC1 data is compiled from several sources (GPS, provincial data, municipal data and NTDB data in some cases). To validate the data we used two methods. When available we used ortho-photos (or other sources) to validate the NRNC1 data. If those sources were not available, we analysed the data and we located specific sites of interest. Those sites were revisited to validate the NRNC1 data. In both cases, if we found errors they were corrected.
