Hydrographic reference files

The hydrographic reference files are provided for the mapping of inland and coastal waters, Great Lakes and the St. Lawrence River. These files were created to be used in conjunction with the boundary files to enable mapping at various scales. The record layout in Table 4.2 below is for inland lakes and rivers (polygons), coast (polygons) and inland rivers (lines).

Table 4.4 Hydrographic reference files feature count by rank
Table summary
This table displays the results of table 4.4 hydrographic reference files feature count by rank. The information is grouped by rank (appearing as row headers), coastal file (number of polygons), lakes and rivers file (number of polygons) and rivers file (number of lines) (appearing as column headers).
Rank Coastal file (number of polygons) Lakes and Rivers file (number of polygons) Rivers file (number of lines)
0 78,290 0 0
1 0 111 0
2 0 3,237 11,442
3 0 3,357 19,221

5 0 19,967 80,914
6 0 64,245 130,012
7 0 124,032 0
Total 78,290 225,822 277,621
Notes: All features within the Coastal file (polygon) are assigned a rank value equal to the value 'zero.'
Within the Lakes and Rivers file (polygons) and the Rivers file (lines), the general guiding principle is that larger features are assigned lower rank values (e.g., 1, 2, 3) whereas smaller features are assigned higher rank values (e.g., 5, 6, 7).
Lakes and Rivers (polygon) features assigned rank value '7' consist of hydrographic bodies and islands having extremely small polygon areas.
Features located outside Canada are assigned a PRUID value greater than 62.

File extension and accented character information

The ArcGIS®, Geography Markup Language and MapInfo® files are compressed into WinZip® files (file extension .zip).

An XML schema file (.xsd) is included to describe and validate the structure and content of the .gml files.

The 2011 Census Forward Sortation Area Boundary File contains attributes with accented characters. They were successfully tested on desktop versions of ArcGIS® 9.3.1 and MapInfo® 11.0.1.

Geographic representation

The 2011 Census Forward Sortation Area Boundary File is available in the following geographic representation:

Datum: NAD83
Coordinates: Latitude and Longitude

The North American Datum of 1983 (NAD83) is an adjustment of the 1927 datum (NAD27) that reflects the higher accuracy of geodetic surveying.

The geographical coordinate system is the primary locational reference system for the earth. This system provides for the unique statement of location for features such as points, lines and polygons.

Users of 2011 Census Forward Sortation Area Boundary File can transform the file into the representation that best satisfies their needs, knowing the effects these representations have on angles, areas, distances and direction.

File naming convention

Spatial product file names follow a file naming convention. The file projection, geographic level, geographic coverage, file type, geographic reference date, software type and language are embedded within the file name. Standardizing the names of the files facilitates the storage of compressed files, all having the extension .zip.

Each file name is 13 characters in length. All alphabetic characters are in lower case to maintain consistency. 

First character: projection of file

g   projection is Geographic (latitude and longitude)

Next three characters: primary geographic level of file/type of file

fsa   forward sortation area
hy_   supporting hydrography (Great Lakes, St. Lawrence River, oceans, etc.)

Next three numbers: geographic code of coverage

000   Canada

Next character: file type

a   digital boundary file
b   cartographic boundary file
c   interior lakes and rivers hydrographic reference file (polygon)
d   interior rivers hydrographic reference file (line)
h   hydrographic coverage of Great Lakes, St. Lawrence River and surrounding oceans

Next two numbers: geographic reference date

The geographic reference date is a date determined by Statistics Canada for the purpose of finalizing the geographic framework for which census statistical data are collected, tabulated and reported. For 2011 Census products, the geographic reference date is January 1, 2011.

11   geographic reference date is 2011
