Title: Large mooring fields along the coast of Massachusetts, 2007
Geospatial_Data_Presentation_Form: vector digital data
Description:
Abstract:
These GIS data show the approximate location of large mooring fields on the coast of Massachusetts. Large mooring fields are defined a contiguous cluster of ten or more moorings. Mooring fields were created by onscreen digitization of mooring fields identified on MassGIS ortho imagery (2001 and 2005) and Pictometry data. The mooring fields data were then checked and augmented by local knowledge (Massachusetts Office of Coastal Zone Management regional coordinators) in the Spring of 2007. These data are not to show exact mooring field boundaries but instead to give the user a general idea where large aggregations of boats are moored.
Purpose:
Component of Massachusetts Office of Coastal Zone Management Human Uses database.

Data_Quality_Information:
Attribute_Accuracy:
Attribute_Accuracy_Report:
All polygons are believed to represent large mooring fields based on ortho imagery and local knowledge.
Logical_Consistency_Report:
A formal logical consistency report was conducted for these data, however, it is believed that the attribute data is consistent and correct with the exception of the NAME field which was abandoned part way through data collection.
Completeness_Report:
Small mooring fields, defined as those with ten or fewer boats, were excluded from the data set. Likewise, any mooring fields regardless of size outside of the coastal zone were excluded.

Process_Description:
Some mooring fields were detectable from the MassGIS ortho photos (2001 and 2005) and Pictometry data and were captured via onscreen digitization. Most mooring fields, however, had been pulled for the season when the MassGIS ortho photos were taken. To capture these mooring fields, large poster sized 1:5000 maps were printed and distributed to MA CZM Regional Coordinators. Using local knowledge, the Regional Coordinators draw known mooring fields onto the posters for their region. The data inherent in these posters was then transferred into GIS by hand digitizing the location of the mooring fields over both the MassGIS ortho photos and the appropriate detailed NOAA nautical charts for the region in question. The resultant polygons were then corrected to ensure they overlaid water deep enough to support moored vessels and did not intersect any land, rocks, bars, or infrastructure such as docks or navigational monuments.
