Description:
 
Abstract:
This data set comprises the Environmental Sensitivity Index (ESI) data for Prince William Sound, Alaska. ESI data characterize estuarine environments and wildlife by their sensitivity to spilled oil. The ESI data include information for three main components: shoreline habitats, sensitive biological resources, and human-use resources. This data set contains hydrology data.
Purpose:
The ESI data were collected, mapped, and digitized to provide environmental data for oil spill planning and response. The Clean Water Act with amendments by the Oil Pollution Act of 1990 requires response plans for immediate and effective protection of sensitive resources.

Native_Data_Set_Environment:
The software packages used to develop the atlas are Environmental Systems Research Institute's ARC/INFO(r) (version 8.0.2) and ORACLE(r) RDBMS (version 8.0.5.0.0). The hardware configuration is Hewlett Packard workstations (models 715/50 and 712/80i with 4 X-terminals) with UNIX operating system (HP-UX Release A.10.20). The following files are included in the data set: bio_lut.e00, biofile.e00, biores.e00, birds.e00, breed.e00, breed_dt.e00, esi.e00, fish.e00, fishl.e00, hydro.e00, index.e00, invert.e00, m_mammal.e00, m_mampt.e00, nests.e00, seasonal.e00, soc_dat.e00, soc_lut.e00, socecon.e00, sources.e00, species.e00, status.e00.


Data_Quality_Information:
 
Attribute_Accuracy:
 
Attribute_Accuracy_Report:
The attribute accuracy is estimated to be "good" given the years of ESI experience, the data-input methodology, the quality control review sessions, and the digital logical consistency checks.
Logical_Consistency_Report:
The digitization of shoreline types, biological resources, and human-use resources is a complex and highly quality-controlled process. Existing digital shoreline data are integrated into a study-wide basemap. In order to facilitate digitizing, the entire study area is split into individual quadrangles using the INDEX data layer. The first layer of information digitized is the ESI shoreline classification. The ESI habitat ranking is compiled onto 1:63,360 USGS topographic quadrangles by a geomorphologist. The hardcopy maps are then digitized and checked using both on-screen and hardcopy reviews. The edited maps are updated, checked once again for completeness and topological and logical consistency. Any errors in the shoreline classification are updated prior to digitization of the biological and human-use layers. All layers use the shoreline as the geographic reference so that there are no slivers in the geographic coordinates. The hardcopy biological information is compiled onto 1:87,000 USGS topographic quadrangles by a biological expert using data from regional specialists in the form of maps, tables, charts, written descriptions of wildlife distributions, and personal interviews. Concurrently, digital data sources are imported, projected, checked for quality control, and integrated into the data structure. The hardcopy data are digitized, checked using both digital and on-screen procedures, integrated with existing data, plotted, and sent out for review by the regional specialists. The edited maps are updated, checked once again, and the final product plotted (at approximately 1:50,000 scale). A team of specialists reviews the entire series of maps, checks all data, and makes final edits. The data are then merged to form the study-wide layers. The data merging includes a final quality control check where labels, chains, and polygons are checked for attribute accuracy. To finalize the data checking process, each coverage is checked using a standardized form by two GIS personnel (a technician and the GIS manager), and each attribute database is checked using several programs that test the files for missing or duplicate data, rules for proper coding, GIS topological consistencies (such as dangles, unnecessary nodes, etc.), and ORACLE(r) to ARC/INFO(r) consistencies. A final review is made by the GIS manager, where the data are written to tape and the metadata are written. ESI data are processed into multiple formats to make them useful to a wider community of GIS/mapping users. Distribution formats include ARC export, MOSS and Shape files, and MARPLOT map folders. An ArcView ESI project and ESI_Viewer product are also included on the CDs for ease of use of the ESI data. The database files are distributed both in the NOAA standard relational database format (see NOAA Technical Memorandum NOS ORCA 115) and in a simplified desktop flat file format. This metadata document includes information on both of these database formats. The section Spatial_Data_Organization_Information refers to the source files in ARC export format only.
Completeness_Report:
The intertidal habitats of Prince William Sound were originally mapped in 1982. The intertidal habitats of Prince William Sound and the Copper River Delta were remapped using two sources. For Port Valdez, Knowles Head, Hinchinbrook Island, and Montague Island, ESI classifications were derived from a database provided by SERVS, Alyeska Pipeline Service Company and generated by Owens and Reimer (1999), based on videotape surveys conducted from 1995 through 1998. For the rest of the study area, ESI classifications were made during overflights conducted by an experienced coastal geologist during 14-19 May 1999. The shoreline classifications were denoted onto 1:63,360 U.S. Geological Survey (USGS) topographic maps. The shoreline classifications were then transferred onto maps on which the shorelines derived from both National Wetlands Inventory (NWI) data and USGS Digital Line Graph (DLG) were plotted. The DLG shoreline was used in most cases; the NWI shoreline and polygons for tidal flats and marshes were used when they best represented the current shoreline conditions, especially in the Copper River Delta and other areas of extensive flats and marshes.

Horizontal_Positional_Accuracy_Report:
The ESI data use USGS 1:63,360 topographic quadrangles as the basemap. It is estimated that the ESI shoreline classification has a minimum mapping unit of 100 feet.

Process_Description:
All the digital data were checked using both digital and on-screen procedures, plotted, checked by the coastal expert, edited to remove any errors, and plotted for review by the regional specialists. The reviewed maps were updated on the computer, checked once again, and plotted at final map scale. A team of specialists reviewed the entire series of maps, checked all data, and made final edits. The data were merged to form the study-wide layers that are described in the document. The data merging included a final quality control check where topological consistency, rules for geography, and database to geography were checked and validated for all relationships.
