It has been subset to the Nelson River drainage area. These sub-sub drainage areas are part of the Standard Drainage Area Classification (SDAC) which was developed by Natural Resources Canada, in partnership with Statistics Canada, and Environment and Climate Change Canada.</p> <p>A drainage area, as opposed to a drainage basin or watershed, is a unit of statistical aggregation used for reporting purposes based upon drainage patterns and the underlying basins, delimited by a drainage divide. A drainage basin, sometimes called a watershed, is an area where all surface water shares the same drainage outlet. Surface water consists of water flowing on the surface of the earth that develops into larger streams and eventually combines to form a river. The 11 MDAs presented in this map comprise the uppermost level in the drainage area classification system which then divides into 164 sub-drainage areas, and then is further divided into 974 sub-sub-drainage areas.</p> <p>The Drainage Areas dataset is largely based on the Water Survey of Canada (WSC) drainage area boundaries at the sub-sub-basin level. The data model supports the derivation, from the Fundamental Drainage Areas (FDA) dataset (sub-sub-basin level), of the WSC and the National Atlas of Canada (NA) (AC) drainage area hierarchies and the data is available in all three schemes. Drainage area definitions for both WSC and Atlas of Canada boundaries were reviewed resulting in some modifications. Larger scale reference data sources were used for further manual boundary adjustments. This dataset has been integrated with other National Scale Frameworks hydrology datasets and is considered a component of the Hydrology Theme.</p> false Nelson River Water Survey of Canada sub sub watershed areas fid 1 1 xsd:int the_geom 1 1 gml:MultiPolygonPropertyType FDA 1 1 xsd:string INTERNAL 1 1 xsd:string DIVERSION 1 1 xsd:string WSCSSDA 1 1 xsd:string WSCSDA 1 1 xsd:string WSCMDA 1 1 xsd:string WSCSSDA_EN 1 1 xsd:string WSCSDA_EN 1 1 xsd:string WSCMDA_EN 1 1 xsd:string WSCSSDA_FR 1 1 xsd:string WSCSDA_FR 1 1 xsd:string WSCMDA_FR 1 1 xsd:string OCEAN_EN 1 1 xsd:string OCEAN_FR 1 1 xsd:string NASSCB_EN 1 1 xsd:string NASCB_EN 1 1 xsd:string NACB_EN 1 1 xsd:string NAMRB_EN 1 1 xsd:string NAODA_EN 1 1 xsd:string NASSCB_FR 1 1 xsd:string NASCB_FR 1 1 xsd:string NACB_FR 1 1 xsd:string NAMRB_FR 1 1 xsd:string NAODA_FR 1 1 xsd:string AREA 1 1 xsd:double PERIMETER 1 1 xsd:double FDA_ 1 1 xsd:long FDA_ID 1 1 xsd:long INTERNAL_1 1 1 xsd:string DIVERSION_ 1 1 xsd:string WSCSSDA_1 1 1 xsd:string WSCSDA_1 1 1 xsd:string WSCMDA_1 1 1 xsd:string WSCSSDA__1 1 1 xsd:string WSCSDA_EN_ 1 1 xsd:string WSCMDA_EN_ 1 1 xsd:string WSCSSDA__2 1 1 xsd:string WSCSDA_FR_ 1 1 xsd:string WSCMDA_FR_ 1 1 xsd:string OCEAN_EN_1 1 1 xsd:string OCEAN_FR_1 1 1 xsd:string NASSCB_EN_ 1 1 xsd:string NASCB_EN_1 1 1 xsd:string NACB_EN_1 1 1 xsd:string NAMRB_EN_1 1 1 xsd:string NAODA_EN_1 1 1 xsd:string NASSCB_FR_ 1 1 xsd:string NASCB_FR_1 1 1 xsd:string NACB_FR_1 1 1 xsd:string NAMRB_FR_1 1 1 xsd:string NAODA_FR_1 1 1 xsd:string WSHED 1 1 xsd:string WSHED_EN 1 1 xsd:string WSHED_FR 1 1 xsd:string
