Abstract:
The hydrology (HYDRO) data layer represents a dynamic segmentation coverage that holds data on water shorelines within Washington State.
The Water Body Shoreline (WS) layer consists of one or more representations of the shoreline of each water body. One representation of the shoreline for each water body will be flagged in the Framework database as the "default" shoreline. This default shoreline will be coincident with the water body perimeter in the water body (WB) layer. This layer is modeled in the Framework to accommodate those instances where multiple shorelines based on different datum (e.g. mean high water, mean low water etc.) are useful, especially marine shorelines. This layer is modeled as a routed linear feature. Water will be on the right side of each route and each shoreline will be represented by one or more non-overlapping routes. However, most simple water bodies (e.g. small lakes and ponds) will likely be represented by a single route. The history of spatial edits to each water body will be stored as an event on the route(s) on the default shoreline. Our agreement is that unless there is good justification to do so, all other shoreline attributes will be stored as events on the default shoreline. Non-default shorelines are intended to accommodate specialized requirements.
Purpose:
For statewide planning and analysis applications and general mapping reference. Provides the framework by which to hang a variety of water related information such as fish habitat, water quality, and water quantity.
Supplemental_Information:
(1) Washington state is divided into two State Plane Zones, north and south. For this data set, north zone data coordinates have been converted to south zone coordinates. (2) Time period of content was derived from an estimated range of publication dates from USGS 1:100,000 scale quadrangles encompassing the state of Washington (from which base data were originally compiled). Specific publication dates should be referenced from individual quadrangles. (3) Initial digital data set was acquired from the Washington Department of Fish and Wildlife. Data shifted to dynamic segmentation under funding from the Bonneville Power Administration (BPA) and is generally referred to as PNW Hydrography Data or PNW data. (4) Ecology's data update phase was completed on 06/1998. The focus of this effort was on water body attribute cleanup and enhancement, water body indexing and unique ID generation, and watercourse routing and ID generation for canals and ditches.

Attribute_Accuracy:
Attribute_Accuracy_Report:
Data attributes values are created and updated within the context of rigorous editing routines. Values are checked for validity within a group of specific ranges or within specific sets of codes. Attribute accuracy of data within the initial phase was tested by manually comparing digital products to the source maps.
Logical_Consistency_Report:
Specified spatial processing tolerances are used to snap arc over-shoots to proximal nodes. Remaining anomalous objects falling outside of specified tolerances are flagged by the software and manually corrected for logical consistency.
Completeness_Report:
Spatial completeness: Statewide coverage. Data Attribute Completeness: Complete.
Positional_Accuracy:
Horizontal_Positional_Accuracy:
Horizontal_Positional_Accuracy_Report:
Accuracy of this dataset is based upon the use of USGS source quadrangles which are compiled to meet National Map Accuracy Standards. NMAS horizontal accuracy requires that at least 90 percent of points tested are within 0.02 inches of the true position (on the map). The digital data are estimated to contain a horizontal positional error of less than or equal to 0.003 inches standard error in the two component directions relative to the source quadrangle. Comparison to the graphic source is used as control to assess digital positional accuracy. Cartographic offsets may be present on the graphic source, due to scale and legibility constraints.
Vertical_Positional_Accuracy:
Vertical_Positional_Accuracy_Report:
The vertical positioinal accuracy is based upon the use of USGS source quadrangles which are compiled to meet NMAS. NMAS vertical accuracy requires that at least 90 percent of well defined points tested be within one half contour interval of the correct value. Comparison to the graphic source is used as control to assess digital positional accuracy. The file has undergone digital revision. Accuracy of the digital data meets the class 1 positional accuracy specifications in the draft United States National Cartographic Standards for Spatial Accuracy.

Process_Description:
This Digital Line Graph was digitized from the USGS source quadrangle, by either the National Mapping Division, one of their cooperators, or one of their contractors. The digital data were produced by on of the following methods. -scanning a stable-based copy of the graphic materials. The scanning process captured the digital data at a scanning resolution of at least 0.001 inches; the resulting raster data were vectorized and then attributed on an interactive editing station. - scanning the paper map. The scanning process captured the digital data at a scanning resolution of at least 0.001 inches; the resulting raster data were vectorized and then attributed on an interactive editing station. -scanning a stable-based copy of the graphic materials. The resulting raster data were then manually digitized and attributed on an interactive editing station. The resolution of the digital data is at least 0.001 inches. -scanning the paper map. The resulting raster data were then manually digitized and attributed on an interactive editing station. The resolution of the digital data is at least 0.001 inches. -manually digitizing from a stable-based copy of the graphic material using a digitizing table to capture the digital data at a resolution of at least 0.001 inches; attribution was performed either as the data were digitized, or on an interactive edit station after the digitizing was completed. -manually digitizing from the paper map using a digitizing table to capture the digital data at a resolution of at least 0.001 inches; attribution was performed either as the data were digitized, or on an interactive edit station after the digitizing was completed. The determination of the DLG production method was based on various criteria, including feature density, feature symbology, and availability of production systems. Four control points corresponding to the four corners of the quadrangle were used for registration during data collection. AN eight parameter projective transformation was performed on the coordinates used in the data collection and editing systems to register the digital data to the internal coordinates used in PROSYS, and a four parameter linear transformation was performed from the PROSYS internal coordinates to Universal Transverse Mercator (UTM) grid coordinates. The DLG data were checked for position by one of the following processes: -comparing plots of the digital data to the graphic source. - comparing the digital data to the digital raster scan. DLG data classification was checked by at least one of the following processes. - comparing plots of the digital data to the graphic source. - comparing the digital data to the digital raster scan.

Process_Description:
The PNW River Reach Files were constructed using ArcInfo versions 4.0 and 5.0. A unique conflation algorithm was developed by the USGS that transferred the reach identifiers from the RF2 to the new 1:100,000-scale hydrography. The 1:100,000-scale hydrography were constructed from scanned 1:24,000 and 1:63,000-scale separates and then edited. Most, but not all hydrographic features found on these two larger scale products will be found in the PNW Reach Files. Water body features such as lakes, reservoirs, defined wetlands, double-banked streams, and others were moved to a separate 'banks' coverage.
Generalized procedures for constructing 100K scale Banks coverages: 1. Read 100K hydrography DLGs for each map into GIS. 2. Edgematch north and west edges of each map to adjacent 100K quads. 3. CLIP each 100K quad with adjusted Hydrologic Unit boundary. 4. APPEND clipped quad pieces together. 5. Correct internal node errors using automated snapping. 6. Remove non-attributed pseudo nodes. 7. Copy polygons to Waterbody coverage. 8. Edit out double-banked streams, shorelines, and braided areas and put into Water bodies coverage. 1. Read 100K hydrography DLGs for each map into GIS. 2.

Process_Description:
The Washington Hydrography Framework 100k Water Shoreline coverage were constructed from the Streamnet banks coverages. Enhancements made were the editing of polygon attributes for water body type code and geographic feature name, creation of a unique identifier based on the latitude/longitude of the water body centroid, and the construction of routes and indexing on the shorelines of certain water body types.
The framework processing procedures were:
1. verifying the DLG water body type codes for each polygon 2. assigning the GNIS feature name to water body polygons 3. assigning a unique Lat/Long identifier to each water body polygon (including islands) 4. building routes on the shorelines for water bodies of types 101, 115, 116, and 421. 5. calculate indexes on the routed water body shorelines in a clockwise direction from the southernmost point on the shoreline 6. calculate an index for the main marine shoreline starting at Point Roberts and continuing southward to the Columbia River
