Description:

Abstract:

Milepost values at one mile increments on mainline state routes derived from the WSDOT 24K Linear Referencing System for Washington State Routes (LRS). This data is updated annually and represents milepost values on the LRS for the year specified in the LRS_Date field.

Purpose:

Milepost values at one mile increments on mainline state routes derived from the WSDOT 24K Linear Referencing System for Washington State Routes.

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.
