- 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,

- 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.
