A variety of framework layers (e.g. hydrology, roads, railways, populated places) have been integrated so that their relative positions are correct. Hydrology (which includes coastline) is the base layer to which all others are fitted. In addition, the Atlas of Canada National Frameworks collection forms a base to which an increasing number of national scale thematic frameworks from other Federal Government agencies are integrated (e.g. ecological regions, census subdivisions). The National Scale Frameworks Hydrology data consists of area, linear and point geospatial and attribute data for Canada's hydrology at a national scale. It provides a representation of Canada's surface water features, and data completeness reflects the content of the source, the original Vector Map level 0 (VMAP0) revision 4 hydrographic layers, except where revision editing has been performed. Key value-added characteristics include river flow direction, connectivity and the tagging of geographical name keys to selected rivers, lakes and islands included in the Concise Gazetteer of Canada. The product set for the hydrology theme consists of six groupings: - Drainage Network Skeleton - Waterbodies - Islands - Drainage Areas - Supplemental Drainage Features (Catchments, Hydrometric Gauging Stations, Station Basins) - Cartographic This metadata applies to the Drainage Network Skeleton, Waterbodies, Islands and Cartographic groups of featutes, of the hydrology theme. The Drainage Network Skeleton dataset is comprised of linear features: single line rivers, flow lines within waterbodies and ocean coastlines. Flow lines within waterbodies are virtual linear features representing the hydrological flow through area features (e.g. lakes, rivers and intermittent waterbodies). These flow lines complete the linear network where rivers would run through lakes, permitting hydrologic network analysis and cartographic generalization. This dataset is required for analytical applications. The coastline component of the Drainage Network Skeleton also delineates oceanic islands. The Waterbodies dataset is comprised of area features: lakes, intermittent waterbodies, islands, and rivers wide enough to be represented as an area feature (e.g. St. Lawrence River, Mackenzie River). In a few exceptional cases, islands had to be represented by "holes" in the polygons in the Waterbodies dataset. Some area features have been subdivided and several types of virtual linear features serve to separate them. Features in this dataset are linked (by an attribute) to their corresponding flow line in the Drainage Network Skeleton. Therefore the Waterbodies dataset may be used in conjunction with the Drainage Network Skeleton for analytical applications. The Islands dataset is comprised of area and linear features: islands within inland waters and the waterbodies and single line rivers within these islands. Oceanic islands are not included as they are part of the coastline component of the Drainage Network Skeleton dataset. The Islands dataset exists to complete the cartographic representation of Canadian hydrology. The Islands dataset is not logically connected with the Drainage Network Skeleton, and can not be used for analytical applications. It should be noted that flow lines of the Drainage Network Skeleton do not take into account of the existence of islands and therefore do not necessarily flow around them. In a few exceptional cases, islands had to be represented by "holes" in the polygons in the Waterbodies dataset. Some islands themselves contain waterbodies and rivers, not significant for network analysis. However, in order to support a complete cartographic representation such waterbodies and rivers have been added to the Islands dataset. The Cartographic dataset is suitable for cartographic or display purposes, but not for analysis. It is a selection of features from the waterbodies, islands and drainage network skeleton datasets but does not include flow lines or other virtual features. The attributes of this data are a duplicate of the data selected from other dataset and are not repeated in this document. Purpose: The Atlas Frameworks are a set of integrated base map layers which form part of a larger National Scale Frameworks data collection. These data have been compiled at a scale of 1:1 000 000 with the primary goal being to indicate correct relative positioning with other framework layers rather than absolute positional accuracy.

Attribute data integrity was also verified using automated procedures to check for anomalies such as duplication of data in fields requiring unique vales and incorrect feature coding. Logical_Consistency_Report: Using ESRI ArcGIS automated reporting, the following were tested for all features: a) arcs begin or end at nodes b) arcs connect to each other at nodes c) arcs do not extend past nodes d) polygons are closed e) All points, lines and polygons are topologically related. Where these statements for arc/node relationships were found to be false, manual editing was performed until automated reporting showed all to be true. Upon completion of all quality control procedures the entirety of this dataset is considered as topologically clean. Completeness_Report: Data completeness reflects the content of the original Vector Map level 0 (VMAP0) revision 4 hydrographic layers except where revision editing has been performed. The selection of features is intended for a scale of 1:1 000 000. All features have been assigned a Digital Geographic Information Exchange Standard (DIGEST) feature code, therefore the completeness of classification reflects the exhaustiveness of the standard's feature coding. Feature name database keys were assigned only to features that were included in the Concise Gazetteer of Canada.

Process_Step: Process_Description: The initial extraction from the source was done using the gettiles software. The gettiles software uses the arcinfo VPFIMPORT command to do the importing task for each tile. The tiles are then assembled. Feature Coding, Logical Checking and Assembly (Nov 1998) - Feature coding, logical checking and assembly were completed. Connectivity Check 1 (Dec 1998) - The connectivity was tested by using the ARC/INFO Network TRACE command. This allowed the user to select all the arcs connected to a particular feature. In this case, a first cut at the connectivity was attempted by determining which features were connected to the coastline. Features which were not connected to the coastline were visually inspected and corrected if deemed appropriate. Quality Control - (Dec 1998 - Jan 1999) - Internal drainage systems mostly on the prairies identified as systems that do not flow to the ocean and their sinks identified and coded on nodes or polygons/lakes where appropriate. Sources used NTS map sheets. It was determined that not all of the water redirections and reservoirs caused by the James Bay power project were represented in the VMAP data. Redigitization of some of these features was necessary (Caniapiscau Reservoir, for example). Sources used Hydro Quebec Map. Updated and highly accurate international boundary information was available from Legal Survey Division. This data was used to update the international boundary. In cases where the international boundary was defined as the centreline of a river, the hydrology layer had to be adjusted to match this. An area where the British Colombia border and the Alaska border reached the coastline was determined to be out positionally. This area was warped using links to correct positionality in relation to the international boundary. Sources International Boundary Commission. Connectivity Check 2 (Jan/Feb 1999) - The second connectivity check identified the individual river systems and by doing a statistical analysis those systems that do not drain to a known sink were identified. Directionality Checks (July 1999 - March 2000) - Using an internal software menu system directionality on rivers was automatically determined. The system was able to automatically assign directionality to approx 90% of the features in the hydrology network. A user then used the nettools menu to manually assign directionality to the remaining 10% of features. Many edits were made to the hydrology network during this phase as most of the areas where directionality was not automatically assigned had connectivity problems that needed to be fixed. These problems included areas of "floating drainage" that didn't have a coastal sink or drainage having more that one sink. Some areas of extremely sparse network connectivity were identified and river systems were added. These areas included south-western Nova Scotia and Storkerson Peninsula on Victoria Island, Nunavut. Skeletonization (July 1999 - March 2000) - For network analysis virtual features were generated through area features to seperate the linear network from the area network. The results of this step are 3 covers where there was 1 before: the linear network which includes the coastline, rivers and water area skeletons, the area features which includes areas of permanent and non-permanent water and then the island areas within fresh water lakes. Make_skel.aml Name Tagging 1 (July 1999 - March 2000) - A database link was created to the Canadian Geographical Names Database, the official repository for toponymy in Canada. The link was created by assigning features within the hydrology network with unique keys used in the Canadian Geographical Names Database (CGNDB). The unique keys to be assigned to features were extracted from a subset of the full CGNDB called the concise gazetteer. Automated procedures assigned names to features and a technician checked and either committed the name to the feature or did the necessary geometry editing to properly assign the name. The process of adding names to features served as yet another connectivity check on the hydrology network and many edits to improve connectivity were made to the hydrology during this step. Drainage Areas Edits (Sept 2001 - March 2003) - A parallel project was started to delineate drainage areas from the drainage network. During the course of this project many problems were discovered and fixed in the drainage network. These problems included errors in connectivity, directionality and feature coding (attributes). Splitting for Stations (Feb 2003 - March 2003) - Arcs in the skel layer were split to create nodes at gauging station locations to provide a link between the two datasets. Additional Attribution (Dec2002) - Two other sets of attributes were added to populate these attribute items. LAKEUID: This attribute, added to arcs in both the skel and isle covers, identifies the UID of the lake in which a given skeleton or lake arc falls. STREAM ORDERING ATTRIBUTES: basin, order1, order2, and order3. Together, they permit the user to trace upstream or downstream using a selection query. This scheme was chosen because it is independent of GIS software -- any software that can make selections based on attributes can perform stream tracing.
