The
Louisiana GIS CD is a two CD set that contains
over 40 spatial layers of geographic data organized
by north and south Louisiana. It replaces a prototype
version released in 1996. The CD is the culmination
of several years of data development and assembly
by sponsoring agencies, and was developed by Louisiana
State University with funding from the Louisiana
Oil Spill Coordinator's Office. The spatial data
on the CD includes a satellite image of Louisiana
with environmental, transportation, boundary,
and geographic data in raster, polygon, line and
point format.
The spatial data are displayed and manipulated
with two Geographic Information Systems (GIS)
that come with the package. These two systems
are ArcView™ 2.1b from Environmental
Systems Research Institute, Inc. and GeoMedia™
2.0 from the Intergraph
Corporation. Vector data are ArcViewÔ
shapefile format and NAD-83 geographic latitude/longitude
coordinates (decimal degrees). Raster data are
packbit compressed geotiffs, NAD-83 UTM zone 15
coordinates (meters).
The
CD comes with a user interface that provides easy
access to instructions and documentation, software
installation, and tutorials. The tutorials provide
help for utilization of the GIS software and introductions
to GIS concepts. The spatial data are accompanied
by fully compliant Federal Geographic Data Committee
(FGDC) metadata. There is also a satellite tour
of Louisiana accessible from the user interface
.
Data
on the CD are the best publicly available spatial
data sources. Additional data compatible with
the CD is available on the LAGIC
and Atlas
web sites. The CD was originally conceived for
Oil Spill Planning and Response, but is applicable
for numerous other applications ranging from environmental
and resource management to political, business,
cultural and demographic. The GIS systems on the
CD provide the ability to view, query, manipulate,
analyze, and perform numerous functions on the
data that will assist in performing research,
creating and plotting unique maps, relating data
based on spatial and feature attributes, and producing
products from the results of custom applications.
