Title: Interpretation of meandering channel in the Mississippi Fan
Publication_Information:
Publication_Place: Woods Hole Field Center
Publisher: U.S. Geological Survey
Description:
Abstract:
This GIS layer contains an interpretive layer tracing a meandering channel
found in the Gulf of Mexico Mississippi Fan.
Purpose:
This GIS overlay is a component of the U. S Geological Survey, Woods Hole
Field Center's, Gulf of Mexico ArcView GIS database. The Gulf of Mexico
GIS database is intended to organize and display USGS held data and provide
on-line (WWW) access to the data and/or metadata.

The SeaMARC 1A sidescan sonar mosaic was registered and viewed in ArcView.
The channel was interactively traced from the SeaMARC1A sidescan sonar
mosaic to create the ArcView GIS layer.

Process_Description:
The SeaMARC 1A sidescan sonar mosaic was registered and viewed in ArcView.
The interpretation of channel locations was then interactively drawn over
the mosaic to create the ArcView GIS layer.

Technical_Prerequisites:
The meandering channel interpretive 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.
