The metadata for this data set are encapsulated into several documents and graphics files. The metadata are not complete if you did not receive the following files along in the data set:
congeog3dlbth.mtd - this metadata in mp (metadata parser) compatible ASCII text form congeog3dlbth.html - this metadata in HTML form congeog3dlbth_faq.html - this metadata presented as Questions and Answers congeog3dlbth.sgml - this metadata in SGML form congeog3dlbth1.gif - thumbnail graphic of data setThe attribute and/or geometric component(s) of the data are provided as Arc export (.e00) file(s) and the corresponding three part (.shp, .shx, .dbf) shapefile(s) or standalone .dbf file(s) in the case an export file is a standalone INFO file. You should have received the following as part of the dataset:

This is a Vector data set. It contains the following vector data types (SDTS terminology):
Horizontal positions are specified in geographic coordinates, that is, latitude and longitude. Latitudes are given to the nearest 0.000000. Longitudes are given to the nearest 0.000000. Latitude and longitude values are specified in Decimal degrees.
The horizontal datum used is North American Datum of 1983.
The ellipsoid used is Geodetic Reference System 80.
The semi-major axis of the ellipsoid used is 6378137.000000.
The flattening of the ellipsoid used is 1/298.257222.

A precursor to this dataset was developed as a surface for numerical wave modeling. This data set was developed in order that the 10 meter depth line could be extracted for other uses. The 10 meter depth line forms a regulatory boundary for dispersant use and in-situ burn pre-approval areas.The user should be aware that meteorological events such as hurricanes may alter these depths or may have already have already altered the actual depths from those represented on the source NOAA charts. Furthermore, geomorphological processes due to sediment load are causing landward migration of isocontours at a rate of about 25 meters per year in the Mississippi River Delta Plain area (east and west of where the Mississippi empties out into the Gulf). Because these data are based on historical NOAA charts, the effects of this migration have not been captured.

Data sources used in this process:
These data represent contours that are oceanward of the the first 2 meter depth line that runs the entire length of the Louisiana Coast. All contours landward of this line have been deleted. The data set has a gap in the region of the Chandeleur Islands. At depths of 1000 meters and greater, the contour interval increases to 10 meters.
Original digitized points were checked with a proximity (anomaly) filter. There are 17 intersection errors in the data set, primarily where neighboring contour lines make contact.
Are there legal restrictions on access or use of the data?

- Use_Constraints:
- These unaltered data may not be redistributed without all of the elements of the metadata listed in the Supplemental_Information section of this metadata document. It is recommended that third parties wishing to use these data obtain them from the Distributor listed in this metadata document.
If these data are altered or incorporated into another dataset, they are not to be redistributed without also: altering the name of the dataset, including a Content Standards for Digital Geospatial Metadata (FGDC-STD-001-1998) compliant metadata file that describes the dataset and reflects the alteration steps that makes the new dataset different from this one, and citing this dataset in the metadata as a source for the altered dataset using the source citation specified below.
If these digital data are used in the production of a report or in the compilation of a standalone printed map, then this dataset is to be cited in the report or on the map using the source citation specified below.
