This dataset contains the White Mountain National Forest Boundary. The boundary
was extracted from the National Forest boundaries coverage for the lower 48 states,
including Puerto Rico developed by the USDA Forest Service - Geospatial Service and
Technology Center. The coverage was projected from decimal degrees to UTM zone 19.
This dataset includes administrative unit boundaries, derived primarily from the
GSTC SOC data system, comprised of Cartographic Feature Files (CFFs), using ESRI
Spatial Data Engine (SDE) and an Oracle database. The data that was available in SOC
was extracted on November 10, 1999. Some of the data that had been entered into SOC
was outdated, and some national forest boundaries had never been entered for a
variety of reasons. The USDA Forest Service, Geospatial Service and Technology
Center has edited this data in places where it was questionable or missing, to match
the National Forest Inventoried Roadless Area data submitted for the President's
Roadless Area Initiative. Data distributed as shapefile in
Coordinate system EPSG:26919 - NAD83 / UTM zone 19N.

The re-use of scientific data has the potential to greatly
increase communication, collaboration and synthesis within and among
disciplines, and thus is fostered, supported and encouraged. Permission to
use this dataset is granted to the Data User free of charge subject to the
following terms:
1) Acceptable use. Use of the dataset will be restricted to academic, research,
government or other not-for-profit professional purposes.
2) Redistribution. The data and metadata are provided for use by the Data User.
The Data User will not redistribute the original Data Set or metadata to
others without the explicit permission of the Principal Investigator.
3) Citation. It is considered a matter of professional ethics to acknowledge the work
of other scientists. Thus, the Data User will properly attribute
the Data Set in any publications or in the metadata of any derived data products
that were produced using the Data Set. Citation should take the
following general form: Creator, Year of Data Publication, Title of Dataset,
Publisher, Dataset identifier.

4) Acknowledgment: The Data User should acknowledge any institutional support or specific
funding awards referenced in the metadata accompanying this
dataset in any publications where the Data Set contributed to its content. Acknowledgments
should identify the supporting party, the party that received
the support, and any identifying information such as grant numbers.
Acknowledgment example: Data on [topic] were provided by [name of PI] on [date].
These data were gathered as part of the Hubbard Brook Ecosystem
Study (HBES). The HBES is a collaborative effort at the Hubbard Brook Experimental Forest,
which is operated and maintained by the USDA Forest Service,
Northern Research Station, Newtown Square, PA. Significant funding for collection of these
data was provided by [agency]-[grant number], [agency]-[grant
number], etc.
5) Consultation and questions. Data users are strongly encouraged to consult with the Principal
Investigator(s) who collected these data for further information. Also, when appropriate,
Data Users should consider including the Principal Investigator as a collaborator and/or co-author
in the use of these data.
6) Notification. The Data User will notify the Principal Investigator of any publication or
derivative work based on the Data Set. The Data User will
also provide the Principal Investigator and/or the administrator of the Hubbard Brook
Ecosystem Study with a pdf or two reprints of any publication(s)
resulting from use of the Data Set.
7) Disclaimer. While substantial efforts are made to ensure the accuracy of data
and documentation contained in this Data Set, complete accuracy of data and
metadata cannot be guaranteed. All data and metadata are made available "as
is". The Data User holds all parties involved in the production or
distribution of the Data Set harmless for damages resulting from its use or
interpretation.

terms of this agreement. The Data Owner shall have the right to terminate
this agreement immediately by written notice upon the Data User's breach of,
or non-compliance with, any of its terms. The Data User may be held
responsible for any misuse that is caused or encouraged by the Data User's
failure to abide by the terms of this agreement.

Most of the data editing tasks were performed using ARC/INFO software. The
data was first converted to an ARC/INFO line coverage, and then projected to
Albers. It was then split into three portions, so three individuals could
edit one portion each. For each of these portions, dangles that appeared to
nearly connect were connected, using a very small tolerance. Where the gaps
were larger, or where it appeared there was data missing, the GSTC SOC
database was queried, using an ArcView browser, and the appropriate line
segment copied if available (some line segments in the original CFF data may
have been coded as other features, but may also have been the nf boundary).
If it did not exist there, hard copy maps were referenced, and the necessary
arcs digitized from the map or on screen using the 1:2,000,000-scale NF
boundary data displayed as a reference. The maps used were generally a
combination of paper or film prints of the 1:126,720-scale Forest Visitor
maps and 1:24,000-scale Primary Base Series Forest Service quads. In some
cases, the data was available in the GSTC PBS quad editing database, or
online, if the quads were in the process of being revised, and the necessary
portions of boundary were then taken from these, as they would be the most
current. When all gaps were filled in, the coverages were used as
backcoverages for reference when edgematching the IRA data from the National
Forests. Pseudo nodes were later removed, and polygon attributes were built
after the three portions of the coverage were appended together. Additional
corrections were made as necessary. The Proclaimed Forest Boundaries were
disolved. The coverage was projected to geographic for analysis and display.
