GIS brings together data layers and analysis
GIS is used by scientists, emergency managers and planners to create data products make maps disseminate information in a timely manner
Data that are georeferenced can be put into a GISMunicipalities are increasingly using GIS to store, disseminate and document land use changes, plan for emergencies and display their data
GIS efforts in NOAA
GIS is being used within all NOAA LOs NOAA Enterprise GIS Working GroupEstablished this yearAll NOAA LOs are represented
PMEL and some other OAR Labs are providing data in a GIS format and distributing GIS products to users
GIS gaining acceptance by science community
Science interest AMS IIPS GIS Session in Feb 2003 Significant NCAR atmospheric modeling GIS effort ESRI sponsored Marine Data Model for GIS science
Benefits of GIS for science GIS increasingly useful for scientific computing
GIS products – paper and electronic maps, maps, sophisticated analysis products and applications
3D Visualization Increasing sophistication in GIS technology allow users to start
visualizing and distributing their data in 3D Support for scientific file formats
netCDF to coverages, shapefiles for in-situ and gridded fields
Getting started with GIS -approaching the CSI project
Who are your users? How will they access the data? Desktop? Web? Field applications?Are the data static? Real time? Will the users be adding their own data?Do you want a to provide a enhanced presentation of your data?Any solution requires this information
OAR Case Studies
PMELTsunami Inundation Mapping Effort (TIME)
program (OAR/PMEL) Cordell Bank (NOS/National Marine
Sancturaries)ShipTracker (OAR/NMAO)
Other OAR applicationsNSSL, GLERL, OE, ARL
TIME – GIS supporting Tsunami Hazard System
Tsunami Inundation Mapping Effort (TIME) program
Creating products for use by emergency managers in five states from model output
Involves ingesting data from municipalities, NOAA, model output, observational data
Data products are maps, both static and live
TIME Demo
ArcView Projects with data products are distributed to Emergency Managers
Live Maps for Hazards
ESRI Live MapServer allows users to click on and off layers to look at census data, inundation and hazards information
Interlayer calculations as an added feature
TIME Capabilities
TIME is able to both ingest data from different institutions and to provide data products back to the states in a format that is commonly used by emergency planners and city officials
Data are easily converted to a GIS format
Very detailed metadata should make the end user confident about the quality of the data they are about to use
TIME Limitations
Data can be hard to reformat, often metadata are missing or not available
Hard to convince scientists that users need the data in format that is easily imported into an ArcGIS project
Requires learning how to use new software to create GIS projects
Cordell Bank – Creating a GIS-based Visualization Project
NOS NMS program is reassessing the management of the Cordell Bank Sanctuary
PMEL was approached to create visualizations for use by sanctuary managers
Cordell Bank Data Layers
GIS layers from NMS – bathymetry, topography, satellite imagery
CTD data from NMFS
Hydroacoustic data from NMFS
Data mapped in ArcGIS, distributed and visualized using VRML
Cordell Visualization
GIS products visualized in 3D e.g. isosurfaces, fencelines
Cordell Application
Application allows users to turn off and on layers, move through data
More complicated time steps are being implemented
Cordell Capabilities
Portable visualizations allow users to inspect their data in more than 2 dimensions
Biological model data combined with physical data layers reveals processes interactions
Data easily disseminated as visualizations and imported into desktop GIS system
Visualizations can be viewed using free software such as CosmoPlayer
Cordell Limitations
Additional data collection can be costly, but since its already being collected,you may as well display it
Metadata may not be complete
Not everyone wants to look at the world in a 3 and 4 D display
ShipTracker- Real time tracking using GIS
Provides real time access to ship locations, now being used with marine mammals and drifting objects
JAVA/JSP front end to a GIS back end
ShipTracker Capabilities
Real time tracking of moving objects
New Technology allows for quicker map updating
Allows projects to display information that they want to
Visualization Capabilities at PMEL
PMEL has extensive visualization capabilities ranging from the I-Desk to the desktop
Ability to ingest GIS formats and standard scientific formats (EPIC, Ferret netCDF files)
Portable projects allow scientists to view data and add their own data to the visualization
PMEL Visualization
Emergency managers use visualizations for public outreach and teaching toolsEasily distributed as animations, VRML, quicktime movies, added to GIS projects
How would we approach CSIGIS is an essential component for CSIProcess Identify CSI ingest and output needs Build data conversion routines if they don’t already exist Determine if the data are better suited for a GIS RDBMS or a simpler
database Create data delivery mechanism that allows users to get data for use on
their own desktop or via the web Create the appropriate metadata to make data more understandable to
end users Determine how data will mesh with the pre-existing municipal and NOAA
layers Build a GIS that will allow for expansion as it grows, using current scalable
technologies
