Summary


General cartographic, analysis and query of jurisdictional (city) information for the three county area as well as the bordering Chelan, Kitsap, and Kittitas counties.

Does not include data for unincorporated areas.

Even though this layer is built from and kept current to the contributing sources, users should may wish to use the separate source data layers when working in a more limited area to take advantage of any information or functionality not transferred to the composite.

CITY_3CO stores only a single user attribute: NAME.

Description


Compilation of city jurisdictional information from six counties: King, Pierce, Snohomish, Chelan, Kitsap, and Kittitas.

Uses the best available information from each of the six counties to produce the composite product.

Updated whenever changes are made to any of the source data sets.

For King County this will be whenever CITY_AREA (parent is CITY_ANNEX) is updated to Spatial Data Warehouse.

Updates are made so that the King County portion of this composite is synchronous with the information in the master King County jurisdiction layer.

Final wrapup script is used to create: CITY_3CO_AREA - cities only across three counties CITY_3CO_UNINC_AREA - cities and unincorporated area across three counties CITY_3CO_JURISDICTION - unpulblished versioin of CITY_3CO_UNINC_AREA that is used by DOT-Transit for internal applications.

4/1/2008

Built first edition from new workflow.

Published to SDW.

Data currency valid as: King County - 200802 Snohomish County - 200712 Pierce County - 200710.

4/1/2008

Workflow was revamped to incorporate automated data import, appending and dissolve.

Though this automated method does not produce as clean a data set as the previous manual effort, the new method allows more frequent updates that can be tied directly to when any of the source data is republished.

In addition, as the Pierce and Snohomish County source data do not include a unincorporated polygon this information is not longer maintained as part of the composite.

The main steps of the routine are: 1.

Import the source components, dropping all items except for jurisdiction name.

Standardizing NAME item and standardizing case of values.

2.

Append the modified components to a single target template.

3.

Dissolve on NAME to remove boundaries within cities that cross county boundaries.
