Why was the data set created?

To provide an addressable address layer. Best for symbolizing road classes and for cartographic representation.

How was the data set created?

1. From what previous works were the data drawn?

   (source 1 of 1)

   Type_of_Source_Media: None
   

2. How were the data generated, processed, and modified?

   Date: 02-Apr-2009 (process 1 of 2)

   Deleted Forest Service Roads from the feature class because they are non addressable. St_Address is cadastral based and these roads were not based on cadastral features.

   Date: 20-Jun-2012 (process 2 of 2)

   St_Address is updated quarterly. A shapefile is created which contains all new type 1 arcs that have been added to the cadastal base - Boundary - since the last quarterly update. Type 1 arcs are street centerlines. These new centerlines are copied and pasted into the st_address layer and their attributes calculated. Some streets are added that are not centerlines. These streets are found by a review of pin_address - a parcel layer with the house addresses attached - and st_address. If a parcel, or group of parcels, has a house address that doesn't correspond to any street around it, then it is determined that a street is missing. An arc is then added from Boundary into st_address and the attributes calculated. Ortho photos are used to determine which arc should be used to represent the street so that it is positionally accurate. Person who carried out this activity:

3. What similar or related data should the user be aware of?

How reliable are the data; what problems remain in the data set?

1. How well have the observations been checked?
   The street name attributes are taken from plats that the Assessor's office creates. These plats make up Boundary - the cadastral base layer. The zipcode attribute comes from the KC GIS Center zipcode layer. Address ranges come from the pin_address dataset that is derived from Assessor data. The KC_FCC attributes are used to break out the streets into different types: Primary, Major, Connector, Freeway and Local. Street names are sometimes compared to the Exicse Tax Affidavits report.
2. How accurate are the geographic locations?
   This data set is conflated to the King County Cadastral Base.
3. How accurate are the heights or depths?
   
4. Where are the gaps in the data? What is missing?
   Contains all known streets within King County.
5. How consistent are the relationships among the observations, including topology?
   Each arc contains a name, zipcode, directional address and type (KC_FCC).

How can someone get a copy of the data set?
