Description:
Abstract:
These data is part of the Conditional Assessment project for the National Park Service.  It currently does not have full Metadata.  This metadata provides minimal information on the dataset until further information can be provided.

There were several reasons we did not receive metadata with these data.
1. Legacy Data
2. Incomplete dataset.
3. Documentation was provided in an incompatible format.

This is version 1 of this metadata document.  As additional information become available it will be added.

Please read the distribution liability section before using this data.
Purpose:
REQUIRED: A summary of the intentions with which the data set was developed.
Supplemental_Information:
Sandy Hook Shoreline Series:

Shoreline map series representing selected years between 1835 and 1994.

1835
1850
1855
1932

These maps were digitized from a 7.5 minute map titled "Historical
Shoreline Changes in New Jersey, 1835-1972" by two grad students at
Boston University in 1994-5, James Lindholm and Tom Harrington.  The 
source map is quite old and fragile, although still in fairly good 
condition (sans folding and water stains).  The map legend lists 34
different historical shorelines over the period in question but James
and Tom felt that only these four could be reliably followed.  Historical
shoreline data was collected by the US Coast Guard using "traditional survey
methods of the 19th century", then corrected to NAD27.  No information on 
season, tides or other characteristics of the survey time or methods is
available.  No notes on RMSE for the hand digitizing of this data were taken.

1954

This map provides coverage of only the northern portion of Sandy Hook.
It was derived from (month?) 1954 b/w nadir-looking photography (scale?) 
that was photointerpreted onto mylar sheets by Jim Allen, NBS, for the wet dry 
contact at the beach.  The mylar was then digitized and simultaneously
georeferenced using XX ground control points collected with GPS (described
below) by Mark Adams (CACO) using GRASS software.  RMSE was not noted.


1970

This map was derived from (month?) 1970 (color?) aerial photography (scale?) 
that was photointerpreted onto mylar sheets by Jim Allen, NBS, for the wet dry
contact at the beach.  The mylar was then digitized and simultaneously
georeferenced using XX ground control points collected with GPS (described
below) by Mark Adams (CACO) using GRASS software.  RMSE was not noted.

1984, 1984v, 1984.bogus
1986, 1986v
1988, 1988v
1990, 1990v
1992, 1992v

These maps were derived from color aerial photography for the corresponding 
years (month?) (scale?) that was photointerpreted onto mylar sheets by Jim 
Allen, NBS, for the wet dry contact at the beach.  Map names with a "v" in them 
are enhanced to include a "vegetation" type of class distinction, simply
"upland, marsh, intertidal".  The map titled "1984" has a gap in the mid-
section where a photo was missing.  The map titled "1984.bogus" uses the 1986
shoreline to fill in this gap.  The mylar was then digitized and simultaneously
georeferenced using XX ground control points collected with GPS (described
below) by Mark Adams (CACO) using GRASS software.  RMSE was not noted.

1993 - Nigel and Jim drove the beach in March 1993 
1994 september 

These maps are derived from dynamic mode global positioning system files
collected in August of each year by Jim Allen, NBS and Nigel Shaw, NPS using
a Trimble Pathfinder Professional (1993) and Art Lange, Trimble Navigation,
using a Pathfinder ProXL (1994).  The GPS units were mounted on all-terrain 
vehicles that were driven along the wet-dry contact.  GPS settings were: 
max PDOP:	SNR:	,etc. --> conditions required for advertised 2-5 meter
accuracy.   Several files were edited and appended to provide complete coverage
of the Atlantic (eastern) side of the Hook using GRASS software.  The bayside 
shoreline is from 1992 (considered stable acc. Jim Allen).  It was also appended
in GRASS.

Ground Control Points

XX Ground Control Points (GCP) were collected in 1993 by Nigel Shaw, NPS and Jim
Allen, NBS with a Pathfinder Professional GPS unit (conditions --> advertised
2-5 meter accuracy).  Examples of GCPs include building corners, pavement
corners and intersections, a cannon spot (what is this called?).  For a 
specific list of GCPs see Jim Allen's field notes.  Each corrected and averaged
coordinate value was exported to GRASS for a point file in addition to being
used as input for referencing the air photo interps.
