Summary:
Tarig Ali has developed the following techniques for visualization of the
quality metrics separately in 2-D: textual, symboling, and dynamic buffering.
He also tried the following methods to visualize quality metrics in 3-D:
solid cylindrical (which represents quality with a solid cylinder with varying
cross-sections) and a new method that constructs a helical model around the
shoreline with the unknown/lesser quality.
Kai-chien (Kevin) Cheng reported on interpolation of the water gauge data
and the satellite altimetry data. Both data sets were used to generate a
mean water surface for the period 1999-2001 (shown in Appendix A).
Xutong Niu gave a presentation (Appendix B) on the progress he has made
in comparing different water surfaces created from different sources. He
also presented the work he has done comparing different shorelines extracted
from different sources.
Ruijin Ma is working on triangulating the Lake Erie aerial photographs.
He has finished one stereo pair. He is currently contacting FDOT (Florida
Department of Transportation) to obtain aerial photographs for the Terra
Ceia area.
Xian Xu has continued developing a framework to support the FTP connection
using the C++ language. He has also cloned the functionality that the old
VB program would handle (networking and caching parts).
Vasilia Velissariou reported that she has finished the comparison between
the 1-hour and the 10-minute average data for the randomly chosen year 2001
(shown in Appendix C).
Action List:
- OSU Mapping & GIS Lab
- Ruijin Ma will work on visualizing the 3-D IKONOS shoreline
to represent elevation differences. He will also work on completing the triangulation
of all the Lake Erie aerial photographs.
- Xutong Niu will work on designing a 3-D visualization tool for
the differences in the coastal model data sets. He will also work on converting
Ruijin Ma's software to ArcGIS.
- Dr. Elaksher will work on the tide-coordination problem.
- Center for Mapping
- Tarig Ali will work on the shoreline prediction system in Painesville.
He will also work on developing visualization methods in 2-D and 3-D that
combine the effect of all of the four metrics.
- OSU Geodesy Lab
- Chung-Yen Kuo will work on finding more altimetry data in Lake
Erie from other satellites and for the year 2002. He will also investigate
the differences between the altimetry data and the gauge station data.
- Great Lakes Forecasting System Laboratory
- Vasilia Velissariou will complete the runs for the numerical
water model program.
- SUNY at Buffalo
- Xian Xu will work on coding the networking part of his program.
He will also complete development of the FTP part.

Future Meetings:
- The next RA only meeting will be held Thursday, March 13
- The next co-PI and RA meeting will be held Thursday, March 27
