========================== Data Content and Structure ========================== The Roads dataset is a feature-based product. A data model is included (Appendix A - Roads Data Model Diagram) with an associated data dictionary (Appendix B - Roads Data Dictionary). ------------------ Feature-Based Data ------------------ The feature type of a road is a spatial vector line. The table below outlines the features and their integration into related datasets. .. csv-table:: Feature descriptions and integration into related datasets. :header-rows: 1 :widths: 20 40 40 :file: data_content_and_structure/feature_descriptions.csv --------------------------------------------- Feature-Based Application Schema (Data Model) --------------------------------------------- The Roads dataset Data Model Diagram is set out in Appendix A - Roads Data Model Diagram. --------------- Data Dictionary --------------- Feature-Based Feature Catalogue ------------------------------- The feature catalogue in support of the application schema is provided in Appendix B - Roads Data Dictionary. Spatial attributes are added to the feature catalogue in the same manner as other attributes for completeness and conformance to the application schema. Table 3 refers to all tables in the Feature Catalogue. .. csv-table:: Feature catalogue. :header-rows: 1 :widths: 25 75 :file: data_content_and_structure/feature_catalogue.csv Feature-Based Content Scope --------------------------- All geometry and metadata for lines within the Roads dataset.
