A new shoreline file has been created for Boston Harbor by digitizing and combining
the most recent charts. Up-to-date digital shoreline files are required to support coastal
geographic information system (GIS) displays that combine data from multiple sources. A
second objective was to compare the Boston Harbor data set with earlier shoreline data
sets, such as the Massachusetts Coastline (1:25,000) derived from USGS DLG topographic
data (MCOAST), and NOAAs Medium Resolution Digital Vector Shoreline (1:70,000), and
recent, high-resolution orthophotographic coverage. Comparisons reveal changes due to
coastal construction as well as discrepancies that need resolution. The present data set
represents the most detailed delineation currently available.
