Title:

Points popular for underwater recreational diving in coastal Massachusetts compiled from the Massachusetts Board of Underwater Archeological Resources, dive clubs, and commercial diving outfitters, 2007

Geospatial_Data_Presentation_Form: vector digital data

Description:

Abstract:

This GIS datalayer shows popular dive sites for recreational SCUBA divers including reefs, wrecks, and jetties and breakwaters off the coast of Massachusetts. The data were compiled from the Massachusetts Board of Underwater Archaeological Resources (BUAR) and web searches of popular diving locations listed by recreational and commercial groups. The list is not exhaustive and site locations are generalized and should not be used to plan dives. These data were updated by CZM on July 2, 2007.

Purpose:

Component of Massachusetts Office of Coastal Zone Management Human Uses database.

Data_Set_Credit:

These spatial data were created by the Massachusetts Office of Coastal Zone Management (CZM) for the Massachusetts Executive Office of Environmental Affairs (EOEA).

Microsoft Windows XP Version 5.1 (Build 2600) Service Pack 3; ESRI ArcCatalog 9.3.0.1770

Data_Quality_Information:

Attribute_Accuracy:

Attribute_Accuracy_Report:

An attribute accuracy report was not conducted for these data although it is believed that all data do represent either a wreck, reef, or jetty or breakwater. All wreck locations were taken from lat/lon coordinate pairs and all reefs, jetties, and breakwaters were taken on USGS 1:24,000 quadrangles or NOAA charts.

Quantitative_Attribute_Accuracy_Assessment:

Attribute_Accuracy_Value: n/a

Logical_Consistency_Report:

No logical consistency report was conducted for these data although all attribute data was checked for obvious errors such as missing attributes or gross errors of location.

Completeness_Report:

Not all wrecks, reefs, and jetties and breakwaters are represented in these data. These data represent only those features that are commonly dived upon per BUAR and web research.

Positional_Accuracy:

Horizontal_Positional_Accuracy:

Horizontal_Positional_Accuracy_Report: Horizontal positions were taken from the BUAR and web research.

Quantitative_Horizontal_Positional_Accuracy_Assessment:

Horizontal_Positional_Accuracy_Value: n/a

Horizontal_Positional_Accuracy_Explanation:

Data about shipwrecks, reefs, and jetties and breakwaters off the Massachusetts coast were compiled from several sources; many without any locational error analysis. As such, a horizontal accuracy value was not calculated. Where there was a conflict in location between two different sources, the values from the Massachusetts Board of Underwater Archeological Resources were used if available.

Vertical_Positional_Accuracy:

Vertical_Positional_Accuracy_Report: Vertical positions were taken from BUAR and web research.

Quantitative_Vertical_Positional_Accuracy_Assessment:

Vertical_Positional_Accuracy_Value: n/a

Vertical_Positional_Accuracy_Explanation:

Data about shipwrecks, reefs, and jetties and breakwaters off the Massachusetts coast were compiled from several sources; many without any locational error analysis. Many sites have estimated depth to the bottom or to unique underwater feature. These data are for the most part anecdotal and rounded to the nearest five foot interval. The vertical position values are directly taken from the source data and no attempt has been made to verify or adjust these data.
