Title: 2degree graticule for Gulf of Mexico project area
Publication_Information:
Publication_Place: Woods Hole Field Center
Publisher: U.S. Geological Survey
Description:
Abstract:
Contains a 2degree graticule for the Gulf of Mexico region. This layer
may be displayed over the ArcView Gulf of Mexico project view to display
a 2 degree grid for the area.
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.

Source_Contribution:
A base file, coast.pix, that included the extents of the Gulf of Mexico
project area was defined using the PCI Remote Sensing software. This file
was georeferenced and was used to develop and quickly edit several different
vector data layers for the area.
Process_Step:
Process_Description:
PCI program GRATIC was used to create a lat/lon graticule at the user specified
interval of 2 degrees for the file coast.pix. The created graticule was
saved in a vector segment in the PCI database file.

Technical_Prerequisites:
The Gulf of Mexico 2 degree graticule (gratic) 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.
