| description:
|
This dataset contains two sources used to determine X, Y coordinates for positions along Washington State highways perpendicular to milepost markers. Locations were collected on the fly from a moving vehicle using Global Positioning Systems (GPS) technology, and using Geographic Information Systems (GIS) processes, the Washington State Department of Transportation (WSDOT) 24k Linear Referencing System (LRS) and the WSDOT Traffic Signs Management Systems database (TSMS). |
