Description:

Abstract:

This data set contains vector line map information. The vector data contain selected base categories of geographic features, and characteristics of these features, in digital form. The information was collected by digitizing the Geologic Map of Louisiana to create a digital overlay of the Geologic Map of Louisiana highlighting geologic areas of the State of Louisiana. The data set only captures areal information from the Geologic Map of Louisiana. It does not include point or line features such as faults, ceniers, or cap rock.

Purpose:

To create a digitized overlay of the Geologic Map of Louisiana for the Louisiana Geological Survey (LGS), highlighting geologic areas of the State of Louisiana that can be updated easily in the future digitally. The data set was digitized from a scanned version of a 1 : 500,000 scale hard copy map of the Geologic Map of Louisiana developed by the Louisiana Geological Survey. The classified data was derived from actual field identification and sampling performed by the Louisiana Geological Survey. Coverage is of the entire State of Louisiana.

Access_Constraints:

None currently, but be aware, as is possible in all government situations, other constraints may have been required and added since the compilation and completion of this metadata file.

Use_Constraints:

Acknowledgement of the National Wetlands Research Center as a data source would be appreciated in products developed from these data, and such acknowledgement as is standard for citation and legal practices for data sources is expected by users of this data. Sharing new data layers developed directly from these data would also be appreciated by NWRC staff (contact staff cited in Distribution Information). These are not enforceable constraints, but are highly desired or expected by the National Wetlands Research Center in exchange for the access and use of NWRC data sets.

These data are not legal documents and are not to be used as such. Users should be aware that comparison with other data sets for the same area form other time periods may be inaccurate due to inconsistencies resulting from changes in photo-interpretation and mapping conventions over time. See Access Constraints, for the NWRC Standard Data Liability Disclaimer.

Any downloading and use of these data signifies a user's agreement to comprehension and compliance with all stated constraints in this metadata. Insure all portions of metadata are read and clearly understood before using these data in order to protect both user and NWRC interests.

Attribute_Accuracy:

Attribute_Accuracy_Report:

The accuracy is not based on a formal quantitative assessment. Field checking was not performed for this assignment. To attain a better estimate of accuracy, a formal re-evaluation of the geology of Louisiana would be necessary. No accuracy assessment was performed for this dataset during this project.

Positional_Accuracy:

Horizontal_Positional_Accuracy:

Horizontal_Positional_Accuracy_Report:

The accuracy of the dataset is dependant on the accuracy of the Geologic Map of Louisiana produced by the Louisiana Geological Survey of Baton Rouge, Louisiana, 1984.

Process_Step:

Process_Description:

Data, in the form of a digitized overlay of geologic areas, was collected from the Geologic Map of Louisiana. Polygons were digitized, in Arcview 3.0, on the computer screen by using a mouse to draw polygons over geologic areas on the scanned version of the Geologic Map of Louisiana. Polygons were subsequently edited and assigned attributes within the Arcview environment. The shapefiles were then converted to ARC/INFO coverages and cleaned.
