What is CERA? Coastal Emergency Risks Assessment Visualization tool using OGC standards Displays the outputs from the ADCIRC storm surge model or other coastal models Represents the maps on interactive websites Works near real-time
Visualize ADCIRC Data Visualization & Graphics Applications Customized ADCIRC Visualization Tools Open Source, Easy Use Commercial, Technical Knowledge Customized Website ADCIRC Analysis Tools ParaView Matlab CERA FigureGen StormSurgeViz (AdcircViz)
CERA Storm Surge Websites tightly coupled to the ADCIRC Surge Guidance System relies on text advisories from NOAA s NHC The ASGS delivers model output from the ADCIRC storm surge model every 6hrs during an active storm CERA provides visualization ~ 1hr after a finished ASGS model run shows ADCIRC results + other information for EMs like storm tracks, precipitation data, gage stations etc. automated notifications system to alert end users
CERA Storm Surge Features Model output: Water elevation (storm surge) Water inundation above ground Wind speed Significant wave height Relative peak wave ADCIRC node attributes Hurricane track information Overlay features: ADCIRC grid barriers NOAA shoreline Background maps: Google Road Map Satellite Terrain Zoomable maps Animations

Predict Flooding KNOWLEDGE TRANSFER CONTROL ADCIRC ASGS CERA Combines atmospheric pressure and wind forecasts to predict when, where and to what extent flooding will inundate a coastal community uses ADCIRC and thousands of supercomputers to generate storm surge guidance in real time for approaching hurricanes enables decision makers to identify which locations to evacuate and to plan for mitigation and response before severe storms occur INFORMATION Global, Regional, Local

Wax Lake Delta Case Study The Wax Lake Delta Case Study compares the CLEAR landscape change module (Visser et al. 2008) to the geoengineering model developed by Parker and Sequiros (2006) Both models are used to investigate delta building dynamics considering different sediment loads within the Wax Lake Outlet.

Open GIS Consortium (OGC) Standards WMS OGC Web Map Service Interface Standard Provides map images of selected data layers in raster formats (PNG, GIF, JPEG, TIFF) WFS - OGC Web Feature Service Interface Standard Provides vector source data (points, lines, polygons) in Geography Markup Language (GML) format.
Why using OGC standards? Ability to use geographic data and layers from other map servers. In this case, the application becomes a WMS (or WFS) client. Share (or serve up) geographic layers to other map servers. This makes an application a WMS (or WFS) server.
STORM YEAR 1 - Shapefiles Will replace the TIFF imagery files used in CERA Direct download from each CERA page see what you get Allows the GIS community to work with shapefiles in ArcGIS Allows flexible color scales Speed? not necessarily better than TIFs
STORM YEAR 1 - Shapefiles Better readability for ADCIRC results with a narrow range of values
STORM YEAR 1 - Shapefiles Better differentiation for daily ADCIRC runs
STORM YEAR 1 - Shapefiles Faster assessment of critical storm situations
STORM YEAR 1 - Shapefiles CERA Casey Dietrich (UNC) Display the downloaded data in ArcGIS with pre-defined color files
STORM YEAR 1 - CERA VIEWER Northern Gulf Coastal Hazards Collaboratory (NG- CHC) Robert Twilley (2011-2013) First version for STORM: 1. Data on local hard drive 2. Local web browser 3. Netcdf format with included mesh information 4. No sharing or download
Usage: cera_viewer.py [path_to_your_adcirc_netcdf_file] 1. Creates a shapefile from the netcdf file 2. Opens a local web browser
