- 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 sensitive biological resource data for
invertebrates.
- 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 and
wetlands data are integrated into a study-wide basemap. 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 reference so
that there are no slivers in the geographic coordinates. The
hardcopy biological information is compiled onto 1:250,000 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 1:87,000
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) and
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. After the data are delivered to NOAA, they are
again subjected to a number of quality and consistency checks.
In the process of checking for topological and database
consistencies, new IDs and RARNUMs or HUNUMs are also
generated. The new IDs are a combination of atlas number,
element number, and record number. In addition, the value used
to represent the element is modified to reflect the type of
feature being mapped. In the case of an element that is
normally represented by a point or polygon, a value of 20 is
added to the standard element value for mapping of linear
features. In the case where an element usually mapped as a
polygon is represented by a point, a value of 30 is added to
the regular element value. The RARNUMs are also modified to
include the atlas number, so multiple atlases can be combined
and RARNUMs remain unique. RARNUMs are redefined on an element
basis, so "resource at risk" groupings will contain only a
single element. HUNUMs are also modified to include the atlas
number. 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:
- Biological information presented in this atlas was
collected and compiled with the assistance of biologists from
the U.S. Fish and Wildlife Service, Alyeska Pipeline Company,
Alaska Department of Fish and Game, and various other agencies,
organizations, and groups. Information collected and depicted
on the maps denotes the key biological resources that are most
likely at risk in the event of an oil spill. Four major
categories, or ELEMENTs, of biological resources were
considered during data compilation: birds; fish; invertebrates;
and marine mammals. The ELEMENTs generally correspond to the
coverage or geographic data layer names. There are also six
attribute, or data tables, BIORES, BREED, SEASONAL, SOURCES,
SPECIES, and STATUS, that are used to store the complex
biological data. The biological polygons (INVERT) are linked to
the Biological Resources table (BIORES) using the unique ID and
the lookup table BIO_LUT, or they can be linked directly using
RARNUM. [The ID is a unique combination of the atlas number
(for Prince William Sound this is 59), an element specific
number (birds are layer 1, fish are layer 2, etc.), and a
unique record number. The RARNUM represents a unique
combination of species, seasonalities, concentrations, and
source information. For each of these groupings, a number is
generated. That number is concatenated with the atlas number to
create a "resource at risk" number that is unique across
atlases.] The items in BIORES include: RARNUM, SPECIES_ID,
CONC, SEASON_ID, G_SOURCE, S_SOURCE, ELEMENT, EL_SPE, and
EL_SPE_SEA. SPECIES_ID is the numeric identifier of each
species and is unique within each ELEMENT. CONC is the
concentration of the species and can be descriptive (LOW,
MEDIUM, HIGH, etc.) or an actual count of the number of
individuals or nests associated with a polygon or point.
SEASON_ID contains a numeric identifier for the unique monthly
presence and life history characteristics of each species at a
given location. There can be one seasonality record per
species, or the same species can have different monthly
presence or breeding activities at different sites. When this
occurs, a new record with a different SEASON_ID is referenced.
G_SOURCE contains the SOURCE_ID for geographic information, and
S_SOURCE contains the SOURCE_ID for seasonality information.
Both items link to the SOURCES data table. EL_SPE is a
concatenation of ELEMENT and SPECIES_ID and links to other data
tables (primarily the SPECIES table). EL_SPE_SEA is a
concatenation of ELEMENT, SPECIES_ID, and SEASON_ID and links
to the SEASONAL and BREED data tables. The SPECIES data table
contains the SPECIES_ID (described above), common name (NAME),
scientific name (GEN_SPEC), date the list of Natural Heritage
Program (NHP) ranks was published (DATE_PUB), biological
element (ELEMENT), biological subelement (SUBELEMENT), and the
NHP global conservation status rank. The item SUBELEMENT refers
to the grouping of the species: (ELEMENT, subelement): INVERT:
crab. The STATUS data table contains records for each species
that is threatened or endangered on state or federal lists. The
items include: ELEMENT, SPECIES_ID, STATE (two-letter state
abbreviations), S_F (state or federal status), T_E (threatened
or endangered status), DATE_PUB (the date the atlas was
published when the given state and federal listings were in
effect), and EL_SPE. The SEASONAL data table indicates the
presence of a particular species in a particular location by
month (JAN-DEC). The BIORES table is linked to the SEASONAL
table using the item EL_SPE_SEA (a concatenation of the first
letter of the ELEMENT, SPECIES_ID, and SEASON_ID). The BREED
data table contains the life stage or life history data for
each unique combination of ELEMENT, SPECIES_ID, and SEASON_ID
(or EL_SPE_SEA). It contains up to 12 records corresponding to
each month of the year that the species is present in that
location. The items BREED1-BREED5 will reflect different life
activities, depending on the ELEMENT referenced. For INVERT,
BREED1 = spawn/mate, BREED2 = eggs, BREED3 = larvae, and BREED4
= juveniles, BREED5 = adults. The SOURCES data table contains
metadata for each biological and human-use source listed in the
ESI atlas. The items in SOURCES include: SOURCE_ID; ORIGINATOR
(author); DATE_PUB (date of publication); TITLE (title of the
data set); DATA_FORMAT (digital type, hardcopy maps, etc.);
PUBLICATION (additional citation); SCALE (source scale
denominator); and TIME_PERIOD (beginning and ending dates of
original data collection). The SOURCES data table is linked to
all biological data at the feature plus species-level and
human-use data at the feature-level. Due to the complexity of
the relational database model, the biological data items are
also post-processed into a flat file format. This file is
entitled BIOFILE and it may be used in place of the relational
files to ease simple data queries. The items in the flat file
are ELEMENT, SUBELEMENT, NAME, GEN_SPEC, S_F, T_E, NHP,
DATE_PUB, CONC, JAN, FEB, MAR, APR, MAY, JUN, JUL, AUG, SEP,
OCT, NOV, DEC, BREED1, BREED2, BREED3, BREED4, BREED5, RARNUM,
G_SOURCE, S_SOURCE, and BREED. All of these items are the same
as their counterparts in the individual files described above,
except the BREED1-BREED5 items. BREED is a newly generated
variable used to link to the BREED_DT file, a modified, more
compact version of the aforementioned BREED file. BREED1-BREED5
give a text summary of when each life stage occurs within that
polygon. The life stages referred to are the same as those
listed in the previous table. The link to the BIOFILE may be
made through BIO_LUT using ID, or it may be linked directly
from the RARNUM in each of the biology cover's attribute files.
As mentioned, BREED_DT is an auxiliary support file to the flat
file structure, which allows the user to do searches based on
month for seasonal breeding activities. The link from the flat
file to BREED_DT is the BREED item. A second supporting data
file is SOURCES. This is the same as the source file described
above, and the link from the flat file is both G_SOURCE and
S_SOURCE. It should be noted that although the flat file eases
data query, it is not a normalized database structure, and
actual updates performed by the states and other responsible
agencies should be done using the relational files.
- Positional_Accuracy:

- Horizontal_Positional_Accuracy:
-
- Horizontal_Positional_Accuracy_Report:
- The biological data sets are developed primarily
using regional experts who estimate concentration areas.
Unlike shorelines, which maintain relative spatial
stability through time, the biological data by nature
vary in distribution across the landscape. Therefore, the
1:250,000 USGS quadrangles are used as a basemap in
gathering the data but the data have "fuzzy" boundaries
which must be understood when utilizing this information.

biological 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.
