Data_Quality_Information:
Attribute_Accuracy:
Attribute_Accuracy_Report:
The thickness attribute is in meters and was derived from analog records
by a generated Uniboom seismic system. The Uniboom employed for this project
gave a penetration averaging 50 m and a resolution of 1-2 m.
Quantitative_Attribute_Accuracy_Assessment:
Attribute_Accuracy_Value: 1-2 m
Attribute_Accuracy_Explanation: Ship motion and equipment limitations
result in this accuracy.
Logical_Consistency_Report:
No additional checks for topological consistency were performed on this
data set.
Completeness_Report: none
Positional_Accuracy:
Horizontal_Positional_Accuracy:
Horizontal_Positional_Accuracy_Report:
Ship position was determined using Loran-C and fixes were recorded every
5 minutes and at course changes. 185-460 m absolute accuracy Typical accuracy
for nonrepetitvie or absolute navigation with Loran-C

Process_Step:
Process_Description:
These hand drawn contours were digitzed from mylar originals using Arc/Info
software. The digitzed data were joined with other Long Island Sound sections
(contours were modified where necessary to match at section boundaries)
and then converted to ArcView shapefile format.

Technical_Prerequisites:
The pgthkl overlay is available in an ArcView shapefile format. The user
must have ESRI's ArcView 3.0 or greater software to read and process the
data file. In lieu of Arcview, the user may utilize another GIS application
package capable of importing the data.
