Abstract:
This data set consists of the vegetative transect lines used in the 1997 Vegetative Type Marsh Map. The data deplicts the length of the marsh type by parish and stewardship. The original data set was collected through visual field observation by Greg Linscombe of LDWF and Robert H. Chabreck of LSU Agricultural Center. The observations were made while flying over the study area (Louisiana Coastal Zone) in a Bell 206 Jet Ranger helicopter. Flight was along north/south transects spaced 1.87 miles apart from the Texas State line to the Mississippi State line. Vegetative data was obtained at pre-determined stations spaced at 0.5 miles along each transect. The stations were located using a Trimble Ag 122 Global Positioning System (GPS) and a computer running Dynamo Geographic Information System (GIS) by GeoFocus. This information was recorded manually into field tally sheets and later this information was entered into a Microsoft Access database. The purpose of the dataset is to display marsh type according to parish and stewardship values along the vegetative transect lines. In Arcview, a spatial join the source data sets was performed. This allowed a merging of the vegetative marsh type, parish boundaries and land stewardship area in a common output file. The output data table was then spatially joined to the transect table to create an output file containing the distance of each transect by vegetative type, parish and land stewardship.

Attribute_Accuracy_Report:
There was no formal assessment of attribute accuracy. The values of the attributes were predetermined with the source data sets. A visual on-screen comparison was performed to ensure the length of transect lines matched the joined attributes. A visual on-screen check was done on the data. There are no omissions within the data set. The quality of the derived data set is equal to the quality of the data set sources.
