### What does this data set describe?

Title:
  Louisiana Rivers and Streams from ESRI/GDT source data, Geographic NAD83, LOSCO (1999) [streams]
Abstract:
  This is a line dataset of rivers and streams in the state of Louisiana. It was derived from an ESRI data set created from Geographic Data Technology, Inc. Dynamap 2000 v7.3 data that was in turn derived from the Bureau of the Census TIGER/Line files.
Supplemental_Information:
  These metadata describe the Arc/Info coverage of name 'streams' and the shapefile of the same name that it was derived from.

  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 with the data set:

      streams.mtd - this document in mp (metadata parser) compatible ASCII text form
      streams.html - this document in HTML form
      streams_faq.html - this document in HTML form
      streams.sgml - this document in SGML form
      streams1.gif - thumbnail graphic of data set

2. What geographic area does the data set cover?

   West_Bounding_Coordinate: -94.043
   East_Bounding_Coordinate: -89.451

4. Does the data set describe conditions during a particular time period?

   Calendar_Date: 1998
   Currentness_Reference: date ESRI data became available

5. What is the general form of this data set?

6. How does the data set represent geographic features?

   1. How are geographic features stored in the data set?

      This is a vector data set. It contains the following vector data types (SDTS terminology):

      - Complete chain (5689)

   2. What coordinate system is used to represent geographic features?

      Horizontal positions are specified in geographic coordinates, that is, latitude and longitude. Latitudes are given to the nearest 0.00001. Longitudes are given to the nearest 0.00001. 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.
      The flattening of the ellipsoid used is 1/298.257.

### Who produced the data set?

1. Who are the originators of the data set? (may include formal authors, digital compilers, and editors)

   - Louisiana Oil Spill Coordinators Office (LOSCO)

2. Who also contributed to the data set?

   > LOSCO gratefully acknowledges the ESRI/GDT agency for providing the source data for production of this data set and LSU for providing the information necessary to build this metadata.

3. To whom should users address questions about the data?

   > Louisiana Oil Spill Coordinator's Office
   > c/o David Gisclair
   > Technical Assistance Program (TAP) Director
   > Louisiana Oil Spill Coordinator's Office
   > Baton Rouge, LA 70804

   > (225) 219-5800 (voice)
   > (225) 219-5802 (FAX)
   > <URL:mailto:tapgis@linknet.idt.net>

### Why was the data set created?

> This data set depicts most of the major and minor streams, rivers and other waterways in the state of Louisiana. Its recommended scales of use are the range 1:35,000 - 1:1,200,000

> This data set in geographic coordinates, NAD83 is a reference 'rivers' theme data set for the Louisiana Oil Spill Coordinator's Office (LOSCO).

### How was the data set created?

1. Where did the data come from?

   LARIVERS (source 1 of 1)

     > ESRI, 1998, Louisiana Rivers.

     This is part of the following larger work.

     Type_of_Source_Media: CD-ROM
     Source_Contribution: shapefile used to create this dataset

2. What changes have been made?

   Date: 1999 (change 1 of 1)
     All unnamed streams were dropped from the LARIVERS data. The remaining stream data set was projected to geographic coordinates, NAD83.

     Person responsible for change:

### How reliable are the data; what problems remain in the data set?

1. How well have the observations been checked?

2. How accurate are the geographic locations?

3. How accurate are the heights or depths?

4. Where are the gaps in the data? What is missing?

   The rivers, streams, and waterways depicted in this dataset are only those that would be present in the primary source dataset which was Bureau of the Census TIGER/Line files which typically have detail standard for 1:100k maps. This data set includes only those streams from the source data set that had names.

5. How consistent are the relationships among the observations, including topology?

   Topological and labeling tests, and attribute statistics were obtained with a quality assurance AML (qa_report.aml). This report is used to expose inconsistencies and problems in the data and its attributes, and to verify correction of those errors when corrections are possible.

### How can someone get a copy of the data set?
