Summary
• Demo of GIS capability on GEONgrid portal• Zoom in to nuts and bolts of “behind the camera”
services• Demo of useful services (on the fly mapping)• Map Assembly Overview (assembling
heterogeneous spatial data type on the fly)• Use of GIS in grid computing

GEON Project:
NSF Large ITR project – collaborative effort GEON is creating an IT infrastructure to
“enable” interdisciplinary geoscience research -- not a group of researchers, but the entire community will benefit
Project started in October 1, 2002 and will continue until September 30, 2007
GEON is one of the first cyberinfrastructure projects funded by NSF!

Ontology Registration (geologicAge.owl)
1. Dataset Registration (myShapeFiles.zip)
2. Item-Level Association (12)
3. GEONsearch
• metadata, spatial, temporal, concept-based
4. GEONworkbench
• use of workspace e.g. composing new maps from existing one

Lets play with it
• Sandbox information– http://www.geongrid.org/– Select Portal Login– Get an portal test account– Login using this account– Upload one the shape file existing on your local
machine

Demo• ShapeToMap
– Have the dataset in shape file format, don’t have expertise/technology to create maps.
• ASCIIToMap– Have tab delimited file, don’t have
expertise/technology to create maps.• XMLToMap
– Have XML dataset in database want create map.• ESRI Grid Ascii to Map (GeoTiff)
– Have a GRID ASCII file, want to create map.

ShapeToMap
• Zip the file associated with a zip file
• Upload the shape file and create map
• View and analyze the results
• URL:

ASCIIToMap
• Tab delimited file with spatial information– Example from the SCEC website (lat, lon,
magnitude)– Only point dataset supported at this points
• Upload the ASCII file and create map• View and analyze the results• URL:
http://data01.geongrid.org:8080/ASCIIToMap/

XMLToMap
• Query database for data– Only point dataset support at this point
• Convert to XML (defined by us)– Spatial information– Attribute data
• Upload the XML file and create map• View and analyze the results• URL:
http://data01.geongrid.org:8080/XMLToMap/

More Formats To Map
• Opportunity to develop your own data converter.
• Publish your conversion tool on GEON and make it available to the world.
