Louisiana Oil Spill Coordinator's Office (LOSCO) 19991000 rdcgeog3dldot vector digital data http://lagic.lsu.edu/loscoweb/ http://atlas.lsu.edu This dataset represents the state maintained primary and secondary road network of Louisiana. The dataset includes Interstates, US highways, and Louisiana State Highways. This dataset was compiled by Louisiana State University from LDOTD source data. The dataset improved upon an existing digital map (linework) that had no attributes. The source dataset was derived from sources including USGS quads, aerial photography, highway plans, DOTD's control section road network and existing general highway maps. The source data set originated in 1983-1985 by digitizing 7.5' USGS quads on high precision input tables, but is updated regularly at LDOTD using the other sources mentioned above. This data set in geographic coordinates, NAD83 is a reference 'transportation' theme for the Louisiana Oil Spill Coordinator's Office (LOSCO). The data is suitable for use at map scales of 1:24,000. In the shapefile version of the coverage, road segments sharing common Interstate, US Route, or Louisiana Route identifiers are merged into single features. In the corresponding Arc/Info coverage these features exist as separate segments, however each segment of the individual features share a unique identifier to allow all segments of a feature to be selected as a group. In many cases the segments comprising a feature are discontinuous. These metadata describe the Arc/Info coverage of name 'rdcgeog3dldot' and the shapefile of the same name it was derived from. These metadata also describe the data set 'primaryroads' which is how this data set (as a shapefile) was named on the 'Louisiana GIS CD: A Digital Map of the State.' The metadata for this data set are encapsulated into several documents and graphics files.

ESRI ArcCatalog 9.0.0.535 Shapefile The final data set was reprojected back to the projection of the original data set to verify spatial consistency with the original data. 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. 60 intersection errors were detected; these probably represent roads that cross, but don't physically intersect (such as overpasses). The data is only actually 95% complete as of March 1999. Louisiana State University 19991000 computer file 19990300 date LDOTD source data was completed LDOTDROADS linework that comprised the road network The LDOTDROADS source data (a Microstation .dgn file) was converted from polyconic projection to geographic NAD83 coordinates using Intergraph MGE. This converted .dgn file was then converted to an Arc/Info coverage. Topology was built using Arc/Info, and the coverage was converted to a shapefile. Linear features were attributed with route numbers taken from the Louisiana Department of Transportation parish highway maps, which were used as a reference. This step required that some segments in the shapefile were broken. Queries of the attributed database were then made to select features for segmentation. The database was then restructured for efficiency of use. Extensive QA/QC checks were made including converting the shape back to a coverage, projecting back to polyconic projection, and comparison of the overlay of that data with the source LDOTDROADS dataset. 1999 withheld Department of Geography and Anthropology, Louisiana State University Hampton Peele mailing address

Baton Rouge LA 70803 (225) 388-3455 hampton@lsu.edu A unique identifier (feat_id) was added to each of the 1633 features in the PRIMARYROADS shape. Those features resulted from the merging of road segments sharing a common combination of interstate, us_routes, and la_routes attributes. The resultant shape was converted to an Arc/Info line coverage consisting of 2707 arcs. Arcs that share a common feat_id may be recovered as individual features. Because the coverage was only 'built,' but not 'cleaned,' the 60 pairs of arcs that cross without intersecting are maintained. 20000104 3001, Inc. mailing and physical address
