Description
Basin Watershed data set shows watersheds in North America at 1:10,000,000. A watershed is an area encompassing part or all of a surface drainage basin, a combination of drainage basins, or a distinct hydrologic feature. Watersheds are mapped in a hierarchical system, with the largest units encompassing the entire drainage areas of major rivers or river systems, or encompassing seaboard areas. Within these large units, subsequently smaller units encompass the drainage areas of smaller rivers and streams. Watersheds are classified differently in Canada, Mexico and the United States; the data set includes a continental classification (the North American Watershed, or NAW level), as well as the classification unique to each country. This data set was compiled from each country’s watershed file and adjustments were made to the data to resolve misalignments and mismatches across international borders.

The most appropriate dataset to use for EGIS would be WMS.
Process for EGIS integration
WMS Service:
WMS can be integrated directly into ArcMap and ArcGIS.
TC Smart Maps:
Not all GIS applications can consume KML file directly due to its unique data structures such as networklinks, folders, models etc.
Please contact Lawrence Chong, Digital Services Directorate for TC Smart Maps KML dataset and format translation.

Customization:
Schema transformation: As required
Denormalization: Not required
Value coding: Not required
Attribute renaming: As required to improve readability
Attribute removal: It is highly recommended as some fields are unnecessary, this will also reduce file size and improve performance
Geoenrichment: Feature symbolization is recommended to improve visualization
Format translation: Not required
Language translation: French version available for most dataset
Update frequency: As identified
