Description:
Abstract:
This is a polygon data set of watershed basin subsegments for Louisiana. The dataset was developed for the LDEQ Office of Water Resources' watershed assessment and management tasks. The basin-subsegments form the management units for water resources used throughout the agency.
Purpose:
This basin-subsegment data is used for water quality planning and regulatory tasks, and form the water quality management units used throughout LDEQ.

Process_Description:
Drainage boundaries were hand delineated on USGS 15 Minute Topographic Maps. These drainage boundaries were then digitized using the Intergraph system by the Computer Aided Design and Geographical Information Systems (CADGIS) Laboratory in the College of Design at LSU.. The Microstation design files were converted to ArcInfo using a Feature-based Import Utility developed by LSU's Remote Sensing and Image Processing( RSIP) Laboratory. Certain drainage boundaries were updated using USGS 24000 Topographic maps.

Process_Step:
Process_Description:
Three subsegment identification and labeling errors were fixed based on consultation with personnel from Office of Water Resources. The IGDS-TEXT field name was changed to SUBSEGMENT. Additional fields were created PLUS4 for subdivision of subsegments, DESC for the written description of the subsegment , BASIN which contain the name of the river basin containing the subsegment,and AREA-SQM (polygon area in square meters) was calculated and the cover was projected to geographic coordinates, NAD27 to produce subseg99g.
Process_Date: 19990500

Process_Description:
Subseg99g was projected to geographic coordinates, NAD83 and converted to a shapefile.
