1. CoreWall: A Visualization Environment for the Analysis of Lake and Ocean Cores Arun Rao – Electronic Visualization Lab, University of Illinois at Chicago Bill Kamp – Insight Access Group Partners Emi Ito, Paul Morin, Doug Schnurrenberger, Anders Noren – Limnological Research Center, University of Minnesota Frank Rack – Joint Oceanographic Institutions Andrew Johnson, Luc Renambot, Jason Leigh – Electronic Visualization Lab, University of Illinois at Chicago GSA Annual Meeting & Exposition Nov. 8, 2004 – Denver, Colorado

2. Nov 8, 2004 Electronic Visualization Lab – University of Illinois at Chicago 2 Introduction Personal Background Experiences in Geosciences –Summer Internship at Limnological Research Center of Univ. of Minnesota at Twin Cities Trained as a core lab tech. Exposed to the Initial Core Description process –Ship time on JOIDES Resolution

3. Nov 8, 2004 Electronic Visualization Lab – University of Illinois at Chicago 3 Goal and Objective Improve the ICD process Digital Line Scan Images –High resolution meter long sections (100 pixels / cm ) Properly lit, Properly focused –Need to be taken advantage of Currently a chore to get core logs onto ICD pages

4. Nov 8, 2004 Electronic Visualization Lab – University of Illinois at Chicago 4 Goal and Objective Ideal Starting Point –Provide display system –Integrate images and sensor logs –Annotations –Database Integration

5. Nov 8, 2004 Electronic Visualization Lab – University of Illinois at Chicago 5 Personal GeoWall - 2 Single PC Display System –Drives six screens –Two screens can be used for polarized stereo Adjustable layout High Resolution –1600x1200 displays – ~11 Megapixels –Can see cores at full resolution

6. Nov 8, 2004 Electronic Visualization Lab – University of Illinois at Chicago 6 Images and Sensor Logs Images of core sections serve as logical blocks Graph multiple sets of data on top of image –Data massaged from multi-sensor track –Graphed using relative scale

7. Nov 8, 2004 Electronic Visualization Lab – University of Illinois at Chicago 7 Images and Sensor Logs Multiple –Data sets –Graphs to a section –Sections to a hole –Holes

8. Nov 8, 2004 Electronic Visualization Lab – University of Illinois at Chicago 8 Not just see,… Need to interact with data –Bring out useful information –Communicate ideas Annotate –Text –Images –Correlative Examples from an Integrated Ocean Drilling Program's preliminary report on right Data Manipulation –Resizing of segments –Log data resize with segments

9. Nov 8, 2004 Electronic Visualization Lab – University of Illinois at Chicago 9 Databases Used to store/manage –Images, Data –Annotations –Chronology of work, Ownership Make use of databases like –JANUS of Integrated Ocean Drilling Program at Texas A & M. –LRCVault of UMN

10. LRCVault Database Automatically presents uploaded files for presentation in a web page. Data files are automatically viewable using the browser’s file associations. Using ODBC, curl or wget we scrape data from other systems into the database using scripts. The system supports dynamic synchronization: Remote copies of the root system are automatically kept up to date using MySql synchronization Large data sets are retrieved from the root system to the remote systems on demand. Data added to the remote systems can be integrated back to the root system as needed. Nov 8, 2004 Electronic Visualization Lab – University of Illinois at Chicago 10

11. Nov 8, 2004 Electronic Visualization Lab – University of Illinois at Chicago 11 Database Integration/Interfacing Retrieve data from remote database –Images (full resolution, thumbnails) –Sensor logs –Perform searches Features to Add: –Upload resulting work –Keep chronology of work “Who worked on what?” “Who started off another person’s work?”

12. Nov 8, 2004 Electronic Visualization Lab – University of Illinois at Chicago 12 Future Work Improve usability (e.g. customized scales) Data manipulation & annotation Increased integration with databases –Collaborate with IODP/TAMU for JANUS –Keep application in framework to allow integration with other databases Try to provide scientists with application to do science
