Description:
Abstract:
This GIS layer contains an interpretive layer
represented by polygons of the thickness
of postglacial sediments in Long Island Sound.
Purpose:
The purpose is to disseminate a digital version of a regional
isopach map showing the thickness of the postglacial
sediments in Long Island Sound

Data_Quality_Information:
Attribute_Accuracy:
Attribute_Accuracy_Report:
The thk_range and max_thk attributes are in meters and
were derived from a TIN model in an effort to account for
gaps in the original data records. Original analog records
were generated by a Uniboom seismic system. The
Uniboom system employed for this project yield an average
penetration depth of 50 m and a resolution of 1-2 m.
Quantitative_Attribute_Accuracy_Assessment:
Attribute_Accuracy_Value: 5 m
Attribute_Accuracy_Explanation:
Ship motion and seismic 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 navigation
and fixes were recorded every 5 minutes and at course
changes.

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

Arc/Info TIN software was used to create a triangulated irregular network
(continous surface model) from the digitzed and edited contours. This model
provided a total volume estimate of postglacial sediments.

New (generalized) thickness contours were generated from the TIN
model. These contours were then built as polygons (edited as
necessary) and then converted to ArcView shapefile format.
