Attribute:
Attribute_Label: Longitude
Attribute_Definition:
 Longitude is a west-east measurement of position on the Earth. It is the angle measured from a vertical plane running through the polar axis and the prime meridian at Greenwich, UK. A line connecting all places of the same longitude is termed a meridian. Longitude is commonly, but not exclusively, measured in degrees, minutes, and seconds. Measurements of longitude range from 0° (Prime Meridian) to 180° West (-180.0) or 180° East (180.0) from this point.

Attribute:
Attribute_Label: RouteID
Attribute_Definition:
A unique Route identifier to identify a route (City,County State, Tribal, Forest) in any given data set. For State Routes, Route IDs are assigned by WSDOT's GIS and Roadway Data Office

Attribute_Definition: Feature geometry.
Attribute_Definition_Source: ESRI
Attribute_Domain_Values:

Attribute:
Attribute_Label: LRS_Date
Attribute_Definition:
The Linear Referencing System date that this record is using for location.
Attribute_Definition_Source: WSDOT Application - DOTS
Attribute:
Attribute_Label: AheadBackInd
Attribute_Definition:
An indicator that denotes if the Milepost is within a back mileage equation area. A back mileage equation area occurs when a segment of a route is added at any point other than the end of an existing route, or when a realignment occurs.
Attribute_Definition_Source: WSDOT Application - DOTS
Attribute:
Attribute_Label: StateRouteNumber
Attribute_Definition:
The number assigned to the State Route and enacted into law by the Washington State Legislature
Attribute_Definition_Source: WSDOT Application - DOTS
Attribute:
Attribute_Label: Latitude
Attribute_Definition:
Latitude is a north-south measurement of position on the Earth. It is defined by the angle measured from a horizontal plane located at the Earth's center that is perpendicular to the polar axis. A line connecting all places of the same latitude is termed a parallel. Latitude is commonly, but not exclusively, measured in degrees, minutes, and seconds. Measurements of latitude range from 0° (at the Equator) to 90° North (90.0) or South (-90.0).
Attribute_Definition_Source: WSDOT Application - DOTS
Attribute:
Attribute_Label: SRMP
Attribute_Definition:
A logical number, assigned by a Linear Referencing Method, to a given point along a State Route. This value will always match the Accumulated Route Mileage value unless there has been a realignment or a jurisdictional transfer which changes the length of a route.
