| What
is the Louisiana GIS CD? |
The Louisiana GIS CD is a two CD set that contains over
40 spatial layers of geographic data including a satellite
image of Louisiana. For a full description in text form,

|
| From
where does the data for the CD come? |
Data on the CD are the best publicly available spatial
data sources. 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. |

|
| From
where can I get the CDs? |
Ordering information can be found on the Louisiana Oil
Spill Research & Development Program website at www.osradp.lsu.edu.
|
| |
|
| Can
I get the data online? |
Yes! Use "Search Atlas." |
| |
|
| What
about the Oilspill CD previously released? |
Version 1, released in 1996, is obsolete and is completely
replaced by this version. |
| |
|
| Can
I use my own GIS to view the data? |
Yes, if your GIS can read ESRI shapefiles. Owners of later
versions of ArcView and Geomedia should be able to read
the files without problems. |
| |
|
| What
if I do not have a GIS? |
The CD provides two GIS to use for displaying the data:
ArcView and Geomedia. The CD provides instructions for
installing either GIS. You do not need both GIS: you can
choose between them. You are encouraged to try both of
them.
Note: the GIS software on the CD only works for
Window-based PCs. Macintosh and Unix users must
provide their own software to view the data. |
| |
|
| Is
metadata provided on the CDs? |
Yes, fully compliant Federal Geographic Data Committee
(FGDC) metadata accompanies each data layer on the CDs.
|
| |
|
| Will
there be revisions and updates to the data? |
Yes, as corrections and revisions are made to the layers
on the CD, they will be updated on the Atlas site. Messages
will inform users of revised data layers. Also, additional
layers will be provided on the site as they become available.
|
| |
|
| In
what projection and datum are the data? |
The vector data on the CD is in geographic latitude/longitude
coordinates (decimal degrees), NAD-83 datum. The raster
data is in UTM zone 15 coordinates (meters), NAD-83 datum.
|
| |
|
| What
are the hardware requirements for using the CDs? |
Minimum
System Requirements: Below are the minimum requirements
to run ArcView or GeoMedia. Since there are very large
data files on the CD, the software will run very slowly
with this system.
