NLD Served(s) as the ‘One

Stop’ data source for
all federal and non
-
federal levee information


Maps and reports produced using NLD data were
exported from the local system (
CorpsMap

+
Sharepoint
) to Google Earth


for distribution
throughout USACE and to external emergency
management agencies such as Missouri SEMA

The map information is exported from CorpsMap to Google Earth just prior to the CMT briefing.

Links to all information are included, such as the CMT briefing packet and photos of field conditions. All necessary
files are managed on Sharepoint for internal USACE use. In June 2010 FTP was used to provide all information to
EMAs, but in the future NWK will use a Sharepoint Extranet.

Any thoughts about emergency management
programs we might look to that are good
examples of how to involve tribes?
