Description:
Abstract:
This is an extract from the State Highway Log that shows the horizontal curve data on state routes based on the increasing direction of travel. State Route identifiers and locations based on State Route Mileposts and Accumulated Route Mileage are also included for geographic reference and for use with the Washington State Department of Transportation's 24k and 500k Linear Referencing Systems.
Purpose:
To enable Geographic Information System users to more easily display and analyze a subset of the data contained in the State Highway Log in conjunction with the Washington State 24k and 500k Linear Referencing Systems.
Supplemental Information:
Additional information can be found in the "State Highway Log", Electronic State Highway Log Data Definitions.doc, and the DOTarmcalc01.txt through the Point of Contact below.
This data reflects the published State Highway Log Planning Report 2011.

Attribute Accuracy:
Attribute Accuracy Report: Values were obtained from the Transportation Information and Planning Support (TRIPS) database.
Completeness Report:
The data contained within the State Highway Log is collected and updated using contract plans, field reviews and information provided by numerous WSDOT Regional and Headquarters offices as well as other county and city sources over the course of a year. This data may have changed since the publication date.
Only those records that have a SRID (State Route Identifier) found in the Washington State Highways at 24K Linear Referencing System can be graphically placed as events. SRIDs that have been added or revised since the completeness date of the LRS will not place, nor will SRIDs for road features not carried by the LRS.

Lineage:
Process Step:
Process Description:
The excel spreadsheets were imported into a file geodatabase. From the file geodatabase, route events were created for the corresponding routes (Inc for mainline and Ramps). Route events were exported into feature classes and merged into one data set. If errors, error messages were reviewed. An EVENTERR column was added, 0 = No Error and 1 = Error.
