HistoryHistory

Provides the ability to selectively access and

interact with data.

Provides users with tools to access data as a web

map service to allow integration with local GIS

data via GIS software and viewers.

Allows users to have the ability to download

source data.

What Does EMHURR Do?What Does EMHURR Do?

SCOPESCOPE Information associated with hurricanes

– Hurricane track/cone of uncertainty

– Watches/warnings

– Satellite

– Wind

– Precipitation

– Flooding

– Limited reference information

Southeastern U.S. September-November, 2003 Primary audience: emergency management community

Internet Map Services (IMS)Internet Map Services (IMS)

What Is It? Allows users to access and interact with spatial

data using only a web browser.

How will IMS Benefit NOAA? Provides a means of viewing NOAA data

resources in a natural map based fashion. Provides a foundation for integrating and

distributing NOAA’s vast data resources using multiple or distributed databases..

Encourages enterprise collaboration among NOAA line offices and programs.
