Description:
Abstract:
This is a first cut at a statewide 1:63,360 coastline. The entire coasline, however, is not 1:63.360; only where data was available as of January 1998. It is a mixture of sources ranging from the Department of Natural Resources, Land Records Information Section hydrography database to the Exxon Valdez Oil Spill Environmentally Sensitive Index coastline (no ESI attributes included) to the US Geologic Survey hydrography to US Forest Service (in Prince William Sound). Where the 1:63,360 data was unavailable the 1:250,000 coastline was used to fill in.
This information does not include lakes or streams. All streams are cut off at the mouth with a straight line.
Purpose:
The purpose of this information is to provide a better coastline for land data to be clipped. It's purpose is cartographic. Before this was created, land data was clipped to a 1:250,000 statewide coastline which did not include many of the islands and did not match well with the 1:63,360 hydrography. Attributes have been added to the arcs, but have not been checked carefully.
This coverage is the first of its kind at this scale; thus there are errors. Please notify DNR, LRIS so these may be corrected.
Note: The USGS is in the process of automating the hydrography statewide at 1:63,360 and should be used as a replacement when the information is ready. This hydrography was not complete and available as of January 1998, and no specific date was set.

Attribute_Accuracy_Report:
null (used to close mouth of rivers), and the Canadian border. Since a mix of sources were used, this was not always calculated. No QC was done to check accuracy. Will be corrected as problems arrise or more time is allowed.
Logical_Consistency_Report: Polygon and chain-node topology present.
Completeness_Report:
DNR, LRIS - reselected the hydrography features coded WATER_TYPE = 'S' or 'N' Did some clean up. EVOS - selected and added as need to fill in. USGS - downloaded ITM quads, where needed to fill in. Selected coastline arcs and closing arcs. USFS, Chugach - selected Prince William Sound coastline and filled in. USFS, Tongass - was included into DNR, LRIS hydrography database.
There are attribute errors. Polygons all closed.

Source used USGS 1:63,360 topographic maps ranging in date from 1950's to 1990's. These were photo revised by BLM. Only hydrography meeting the needs of the State Status Plats were automated. Arc features were coded with source and water type. US Forest Service, Tongass hydrography data was integrated into datbase to fit DNR's model.

Chugach National Forest has had significant changes in their shoreline, particularly near Columbia Glacier and Copper River Delta. They have generated a new coastline to reflect these changes. This information was selected and added as the best source for Prince William Sound.

Source_Contribution: Was used to fill in missing areas of data.
Process_Step:
Process_Description:
From the DNR, LRIS hydrogrpahy, the arcs were selected where water-type = 'S' for shoreline or 'N' for null (closing mouth of streams). This information was used first as it had the most logical coding for arc attributes. The USGS information was downloaded from the web where holes existed. EVOS was used to fill in also. USFS, Chugach was used to completely replace the Prince William Sound area. The statewide 1:250000 alaska coastline was used to fill in where no other data was available. Attributes are structured the same as the ADNR, LRIS hydrography and were added. The attributes were not qc'ed and has errors.
Process_Date: 19980101
Process_Step:
Process_Description:
Step 1: Data set was unprojected to geographic coordinates converted from North American Datum 1927 (NAD27) to North American Datum 1983 (NAD83) using the Arcinfo workstation "PROJECT" command with the NADCON operator. Step 2: Used the Arcinfo "BUILD" command to build the coverage as a Polygon. Step 3: Buillt a spatial index on the polygons and arcs using ArcCatalog and indexed fields that may be queried.
