A combination of first- and second-level or second- and third-level names of the agency that operates a network.
The website address of the agency that operates a network.
The first-level name of the agency that operates a network (e.g., Government of Yukon).
The third-level name (e.g., branch) of the agency that operates a network (e.g., Water Resources Branch).
The degree of closeness of the location coordinates to the true location on the ground. Some coordinates are quite inaccurate (e.g., to the nearest minute as read from small-scale topographic maps). Some coordinates are quite accurate (e.g., to the nearest 10 metres from a GPS unit). Note, however, that the base maps used on yukonwater.ca are biased slightly relative to GPS locations, such that GPS coordinates are not as accurate as implied. Coordinates of unknown accuracy should be considered inaccurate.
A datum is a mathematical model that provides a smooth approximation of the earth's surface. The datum is a reference for defining location coordinates. The coordinates of a location on the earth will vary slightly among datums. The standard datum for the Yukon Water Data Catalogue is the North American Datum 1983 (NAD83). The base maps displayed on yukonwater.ca are in NAD83. The World Geodetic System 1984 (WGS84) datum, which is commonly the default datum of GPS units, is considered equivalent to NAD83 throughout Yukon. Coordinates that were not in either NAD83 or WGS84 were transformed to NAD83 for inclusion in the Yukon Water Data Catalogue. If the datum is unknown, the associated locations are potentially inaccurate.
A qualitative indicator of coordinate quality based on coordinate accuracy and datum. If coordinate quality is either poor or suspect, then the mapped location is a poor or possibly poor representation of the actual location of the site.
The method used to determine the location coordinates of a network sample site, such as by reading coordinates off of a topographic map (potentially inaccurate); digitizing from a point plotted on map or air photo in the field onto a digital map or air photo in a computer (potentially fairly accurate, notwithstanding mapping errors in the field); or by a GPS (Global Positioning System) unit in the field (usually fairly accurate, especially as of May 2000).

The major drainage basin (watershed) occupied by a network sample site. Drainage basins are from the Water Survey of Canada and Atlas of Canada Drainage Areas dataset, which are compiled at a scale of 1:1,000,000. Sites were associated with drainage basins by overlaying site locations on the drainage dataset. Some sites may have been misclassified because of inaccurate site locations and scale-related errors in drainage boundaries.
The 1:250,000 scale Canadian National Topographic System mapsheet number occupied by a network sample site. Sites were associated with mapsheets by overlaying site locations on the mapsheet dataset. Some sites may have been misclassified because of inaccurate site locations.

A code representing a particular sample site in a particular network. Network site codes are provided by the agency that operates the network. Network site codes are unique within networks but not across networks. The combination of network site code and either network name or network code form a unique identifier for the site within the Yukon Water Data Catalogue dataset.
A name used to refer to a particular site in a particular network. Network site names are provided by the agency that operates the network. The names typically reference a location, such as a river, mountain, or community. Network site names and codes are sometimes the same. Unlike network site codes, network site names may not be unique within or across networks.
Any additional notes pertaining to a network sample site.
A more specific website address, such as for accessing a network's data, as provided by the agency that operates the network.
The type of network identifies the overall focus of water sampling for the network. Other types of sampling may occur at the sites within the network.
Identifies in general terms the annual schedule of sampling at a site by a network (e.g., seasonal, continuous, miscellaneous). Sampling during the operation schedule occurs at a particular frequency.
Other agencies involved in sampling sites for a network on behalf of the agency that operates the network.
A particular type of measurement or observation made at a network sample site. Parameters have a unit of measure. Parameters are grouped into parameter classes and into sample types.
A list of parameter classes taken at a network sample site. A parameter class is a group of related measurements or observations. Parameter classes are grouped into one or more sample type, and are further sudivided into parameters.

Indicates whether or not sampling equipment was relocated to or from this site; or whether or not the sampling equipment was moved within a network sample site. Additional information about the relocation may be in the associated relocation notes. The Yukon Water Data Catalogue dataset does not include a column that associates relocated sites.
Notes pertaining to site relocation.
Identifies the interval between sampling events at a site by a network.
A list of sampling frequencies and operation schedules for a network sample site (format: Frequency Schedule (status)). Frequency is the interval between sampling events (e.g., Weekly). If sampling is carried out on a seasonal basis (e.g., during summer only), then Schedule is Seasonal (e.g., Weekly Seasonal) . If Seasonal is not stated, then the sampling schedule is either year-round or not specified. If a sampling frequency is not currently in use at the site, then status is discontinued (e.g., Weekly Seasonal (discontinued)). For definitions of terms, see attributes Sample frequency and Operation schedule and their associated attribute values.
