This data set contains point locations of geothermally active areas as compiled by Motyka et al., 1993. Because of the variety
of geothermal activity present at any given site, each site has been mapped according to the dominant style of geothermal
activity (i.e. water dominated sites, vapor dominated sites, or sites of known subsurface activity). It is important to note
that at any given site, a combination of vapor, water, and subtle indicators of subsurface geothermal activity is most likely
present.This data set comprises a portion of the Environmental Sensitivity Index (ESI) data for Aleutians East Borough and
Aleutians West Coastal Resource Service Area (CRSA). These data identify the marine and coastal environments and wildlife.
The ESI data include information for three main components: shoreline habitats, sensitive biological resources, and human-use
resources.

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.

Use Constraints: DO NOT USE MAPS FOR NAVIGATIONAL PURPOSES.Besides the above warning, there are no use constraints on these
data. Note that the ESI database should not be used to the exclusion of other pertinent data or information held by state
or federal agencies or other organizations. Likewise, information contained in the database cannot be used in place of consultations
with environmental, natural resource, and cultural resource agencies, or in place of field surveys. Recognize that the information
contained in the ESI database represents known concentration areas or occurrences of natural, cultural, and human-use resources,
but does not necessarily represent the full distribution or range of each species or resource. This is particularly important
to recognize when considering potential impacts to protected resources, such as endangered species, wetlands, etc. Acknowledgment

Native Dataset 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 UNIX operating system (HP-UX Release A.10.20), and PC's with Windows Operating System (NT4.0/2000).
The Spatial_Data_Organization Information section refers only to the source files in the ARC export format. The following
files are included in that data set: birds.e00, bio_lut.e00, biofile.e00, biores.e00, breed.e00, breed_dt.e00, esi.e00, faults.e00,

AbsoluteExternalPositionalAccuracy
name Of Measure Horizontal Positional Accuracy Report
evaluation Method Description
It is difficult to estimate the positional accuracy of the data, except to state that each geothermal site's latitude and
longitude, as published in 1993 by Motyka et al., were compiled and plotted on hardcopy basemaps at scale of 1:250,000 and
1:63,360 (in the case of Unalaska). The coordinates provided in Motyka et al, 1993, are general site locations only, typically
with more than one geothermal feature present.
Completeness Commission
evaluation Method Description
This data set is a condensed version of the information presented in Motyka et al., 1993. In the original work by Motyka et
al., geothermal sites were presented in a table listing all observed geothermal features (i.e. fumeroles, mud pots, hot springs,
warm springs, steaming ground, etc.) at each location. As such, each site had a unique combination of geothermal activity
types. To avoid mapping 56 individually attributed points, each site is mapped according to the dominant type of geothermal
activity. Hence, the spatial data set produced from the Motyka et al. table has less detail than the original compilation.
ConceptualConsistency
measure Description
A multi-stage error checking process, described in the above Attribute_Accuracy_Report, is used to verify both attribute accuracy
and logical consistency throughout data production. This process includes multiple automated logical consistency checks that
test the files for missing or duplicate data, rules for proper coding, GIS topological consistencies (such as dangles, unnecessary
node, etc.), and ORACLE(r) to ARC/INFO(r) consistencies. A final review is made by the GIS manager, where the data are written
to CD-ROM and the metadata are written. After the data are delivered to NOAA, they are again subjected to a number of quality
and consistency checks.
notes: This metadata was automatically generated from the Content Standards for Digital Geospatial Metadata standard (version FGDC-STD-001-1998)
using the 2015-07-24 version of the FGDC RSE to ISO 19115-2 transform.
