GIS Data Catalog

Using data provided by Kitsap County for their Puget Sound shoreline, updated WTRBDY_AREA using the UPDATE tool.

The polygon provided by Kitsap was a land polygon.

A background polygon was created and the land erased, creating a water image.

This polygon was used to UPDATE the master database with the BORDER option unchecked (remove outer border after update).

This process updated all those areas where WTRBDY_AREA's edge fell within the Kitsap representation, generally moving the edge of water inland.

Where WTRBDY was currently shoreward of the Kitsap representation, no update was preformed.

These areas will be manually-edited.

Updated WTRBDY by 2010 ortho imagery.

Also compared data from Covington with KC WTRBDY for updates.

At same time updating WTRCRS so that WTRBDY aligns with WTRCRS.

Rate = BAD features were removed.

These BAD features were features originally coded as waterbodies prior to the 2007 imagery update.

Reviewing against the 2007 imagery indicated that these features are not valid waterbodies.

Editors are instructed not to remove feature during review, but to code RATE = BAD.

The BAD features were written to a shapefile in the SupportingData folder in the workspace.

Misspelling for 'South Fork Snoqualmie River' fixed.

Misspelling for Hanson Reservoir corrected.

Lake Garrett (in Lakewood Park in White Center) is renamed Hicks Lake.

This is based on input from the public, internal usage, and USGS GNIS reference.

The lake still maintains the alternate name of Lake Garrett.

CHANGE IN GEOMETRY MODEL FOR PUBLISHED SDW VERSION: Prior to publication of user version to Spatial Data Warehouse the following geometry revisions are made programatically.

1.

Freshwater islands are erased from underlying double-banked stream geometry 2.

Manmade over-water features (Dams, wiers, docks, etc) are erased from the underlying waterbody.

CHANGE IN PRIMARY GEOMETRY MODEL: Marine island polygons (those in Puget Sound, including Vashon), and Mercer Island polygon were permanently removed.

The tide line in Puget Sound has been removed.

The existing version of WTRBDY depended on Geodatabase Coded Value Domains (CVDs).

These relate a stored integer value to a look-up value in the CVD.

To make the resulting SDW featureclass and shapefile appear similar and to ensure that attribute value persist even when changes to the look-up value of the CVD changes, the information in the CVDs is hardcoded into the schema of the version of WTRBDY_AREA posted to the SDW.

This required addition of the following items: STATUS_CD - Integer value for STATUS item WATER_CD - Integer value for WATER item SUBSET_CD - Integer value for SUBSET item TYPE_CD - Integer value for FEAT_TYPE item SOURCE_CD - Integer value for SOURCE item.

General maintenance items based on user feedback.

- Angel Lake renamed Angle Lake - Howard Hansen Reservoir was incorrectly labeled Chester Morse Lake.

Corrected.

- A small slough north of Mercer Slough Nature Park was edited so that the land between the two branches of the slough appears as non-water rather than an island.

Final quality assessment and validation prior to version 1 edition

Assign and validate coded-value-domain assignments and final modifications to schema.

Update with 2005 and 2006 imagery on township tile-by-tile basis.

Includes quality review of existing 2002 features.

Establish history capture and topology relationships.

Complete tile-by-tile editing on 7500 tile scheme based on 2002 imagery

Double-banked stream editing and publication of BIGWATER

Establish edit base from legacy and external data

Pilot area project

Significant edge of water development

WTRBDY was created in a 1997 joint project between WA Dept of Ecology and King County Water and Land Division from an initial source coverage of the standard WA Dept.

of Natural Resources hydrography layer.

This data set is integrated from numerous sources, primarily at 1:24,000 scale.

More information about this initial version, some of which still applies to the current version, can be found in this supplemental document.

Beginning in 2001, WLRD started updating this coverage with additional information from other jurisdictions and field data.

Updated Covington polygons to be detention ponds not lake or pond.

Renamed Hicks Lane to Hicklin Lake.

Added name to Lake Kenyon.

Updates using 2007 (July-August) Pictometry Orthoimagery begun.

Per editing rules outlined in DataSet Overview, this imagery was used to check and update all features within the imagery project area.

New features added and source code updated.

Boundaries of existing features are edited if adjustment required is minor; otherwise existing feature is moved to OLD status and new feature created.

For all features, reviewed and/or edited, the source code was updated to reflect 2007 review.

See Project Plan for additional details.

Columns AA thru AN were completed at the start of the update.

Three additional editors were assigned areas east of Column AN to assist in completing review of WTRBDY_AREA against the 2007 imagery.

They worked on aerial waterbodies only, double-banked streams and edge-of-water (Puget Sound) are being handled separately.
