National Center for Tsunami National Center for Tsunami Research (NCTR)Research (NCTR)
• Designs and develops tsunami detection devices and build monitoring systems
• Provides research, development and implementation of numerical models for tsunami operational forecasts and warnings
• Conducts research and development to improve methods of calculating tsunami impacts on populations and coastal communities

• Buoy siting and optimization studies• Static briefing maps • Atlas for data dissemination and
management• Standalone tools for visualization and
data modeling• Short Term Inundation Forecast tools

GeoModelerGeoModeler Tsunami GIS goalsTsunami GIS goals
• Demonstrate how scientific models and GIS can be integrated more closely in order to model tsunami events and their effects
• Build stand alone application that does not require ArcGIS or the web for deployment
• Application will run geoprocessing events on tsunami model outputs for emergency preparedness analysis and planning
Everyone already uses GIS, why is Everyone already uses GIS, why is this such a big deal?this such a big deal?
• Models are not easily integrated into GIS• Data and models do not operate
independently of each other, no matter how it appears
• Model data formats are hard to integrate into GIS – irregular grids, many time steps, multiple variables within one run
• Often requires glue or bridge to integrate modeling inputs into GIS or just brute force
Integrating data sourcesIntegrating data sources
• GIS information includes– Basemap data– Road networks
• evacuation routes
– Census Data– Emergency
Services
Model integrationModel integration
• Application uses pre-processed MOST model results
• Prototype for Tsunami GIS is based on Geomodeler using Geotools and VTK (Vance AMS 2007)
• Eclipse JDT and ArcEngine JAVA for development
Tsunami GIS outputTsunami GIS output• Pan, zoom, and
identify features• Chose a source
region and magnitude then run the scenario
• Resulting map shows areas affected
• Information window gives total population affected including elderly and at risk
• Can be used for emergency responders during real time or for scenario planning
Visualization for emergency Visualization for emergency managersmanagers
• Visualization is not just static maps and reports
• 3D output from model can be integrated with GIS layers to provide emergency managers useful tools for analysis and display
• Integration and output to Google Earth is possibleSeaside Oregon 3D View
Lessons learnedLessons learned
• Direct read in netCDF has made model integration into ArcGIS much easier
• Visualization of the model process using model-builder and customization with python makes GIS-wary modelers more comfortable using GIS for visualization and analysis
• Integration of OpenDAP and other web services to add data adds functionality for tsunami or any other modeling to GIS application
Challenges encounteredChallenges encountered
• Data integration, not all netCDF is standard• Getting modelers to use a new application is
challenging, using off the shell application is even more of a challenge
• Data granularity – fine scale of census data versus modeling the entire Pacific basis
• Adapting to rapidly developing technologies e.g. Google Earth
• Integrating social science into science
Future applications/opportunitiesFuture applications/opportunities
• Better integration with NCTR desktop inundation modeling tools
• Integration with PRIDE funded Seaside, Or. Vulnerability Study
• Expanding tools for use with other types of inundation models (e.g. storm surge models)
• Improved 3-D visualization
