1 Introduction
For the coastal regions of Maryland, the Maryland Geological Survey (MGS) has periodically compiled
maps depicting shoreline position at several points in time.  The most recent compilation -- the first
electronic one -- involved (1) digitizing historical (1841-1977) shoreline maps, all derived directly or
indirectly from National Oceanic and Atmospheric Administration coastal survey maps (topographic or
T-sheets), and (2) interpreting recent (1988-1995) shorelines from digital orthophotography.  MGS is
using the shorelines to update a series of Shoreline Changes maps and to determine coastal land loss,
by watershed and by county, during the last half of the 20th century.

2 Contents of this CD-ROM (ArcShore_2003)
This CD-ROM, ArcShore_2003, contains past shorelines, dating from 1841 to 1995, for 125 7.5-minute
quadrangles covering the coastal regions of Maryland (see below).  Originally in MicroImage's
TNTmips .rvc format, the shoreline vectors have been converted to Arc/Info "Export" (.e00) format.  They are registered to the Maryland State Plane Coordinate System (North American Datum of 83, meters).

Files are located in directories assigned the full name (concatenated) of the 7.5-minute quadrangle.  The four-character file name indicates the shoreline year.

In addition to the shoreline vector files, the CD-ROM also contains four metadata or data
documentation files, each in two different formats.  The digital shorelines are a product of four different projects.  Each set of shorelines generated as part of a particular project was documented separately.  In the interest of making the set of Arc shorelines available immediately, the original metadata files have been copied to the CD-ROM.  They have not been combined.  Nor have they been changed to reflect the Arc format on this CD-ROM.  Other than that, however, the metadata apply.  The names and content of the four metadata files, found in the Metadata directory, are:

1. Historical - Historical shorelines, 1841-1976, Chesapeake Bay region of Maryland,

2. NCoastBay - Historical shorelines, 1849-1989, northern coastal bays of Maryland (Assawoman Bay, Berlin, Ocean City, Public Landing, Selbyville, and Tingles Island quadrangles),

3. SCoastBay - Historical shorelines, 1843-1989, southern coastal bays of Maryland (Boxiron, Girdletree, and Whittington Point quadrangles), and

4. Recent - Recent (ca. 1990) shorelines, coastal regions of Maryland.

The metadata files comply with the Federal Geographic Data Committee's "Content Standards for
Digital Geospatial Metadata" (June 8, 1994).  Two versions of each metadata file are provided - one
(.txt) in ASCII format and one (.wpd) in a more easily read format, Corel WordPerfect 6/7/8.
