OSU Center for Mapping: Tarig Ali
SUNY at Buffalo: Xian Xu (reported by E-mail)

Every effort should be made to attend the meeting

Vasilia Velissariou reported that she has been looking at the system Sean O’Neil was working on. She gave a presentation about the water surface modeling system (see Appendix A ). She found that:

1. Sean prepared the meteorological data and the gauge-station data (every 6 hours) to generate a three-year average water surface (1999-2000). The water-gauge data is complete for this time period at the three stations (Toledo, Buffalo, and Cleveland). The model was run for this time period.
2. Sean prepared the meteorological data for the 10-year water surface but he didn’t run the model to generate the 10-year average water surface. The water gauge data for the 10 years is not complete.

Xutong Niu reported that he has worked with Xian Xu on the remote data access demonstration and finished the required functions: downloading data from three different sites (Buffalo Server, PC server and Unix Server in Mapping and GIS lab), displaying and overlaying functions, and unzipping functions. He also checked the gauge station data for generating the water surface with Chung-Yen.

Tarig Ali reported that he has obtained coastal erosion maps in digital form for Painesville, OH from Don Guy at ODNR. This data set includes transects created along the shoreline and have been used to compute erosion rates. He has also obtained the 1973 and 1990 shorelines for Painesville (to add to the 1979 USGS shoreline we already have).

Ruijin Ma reported that he has been preparing the data inventory for the new Tampa Bay site (see Appendix B ). He has prepared the IKONOS and aerial photo 3D shorelines for the data assessment task. He is also working on filtering the IKONOS DEM.

Ahmed Elaksher reported that he has started to study the intersection between a horizontal surface and the CTM to generate a tide-coordinated shoreline (see Appendix C ).

Xian Xu reported that he and Xutong Niu have finished a demo version of the remote data access program that can display data from multiple sources. The program can deal with three types of data sources that are stored on three different servers.

Kai-chien Cheng reported on the statistical analysis of the differences between the GPS buoy and Marblehead tide-gauge data sets (see Appendix D ).

Chung-Yen Kuo reported that he is done with the water data analysis.

• OSU Geodesy Lab

• Chung Yen will work on generating the following water surfaces in Lake Erie: MWS for the years 1999, 2000, and 2001. He will also work on generating the 3-year average surfaces.

• Great Lakes Forecasting System Laboratory

• Vasilia Velissariou will work on generating the 3-year average water surfaces (1999-2000). The surfaces required are MWS, MLLWS, and MHWS. She will also investigate the model used in generating the water surfaces, in particular:

1. Data used in generating the fluctuating water surface.
2. Gauge stations involved in generating the mean water surface.

• OSU Mapping & GIS Lab

• Xutong Niu will help Xian Xu on accessing data in USGS website and making Ruijin's program to access different data sources. He will complete working on the shoreline accuracy investigation.
• Ruijin Ma will complete the data inventory for Tampa Bay. He will also work on evaluating the 3D shorelines generated by the aerial photos and IKONOS imagery. Ruijin will also complete filtering the IKONOS DEM.
• Ahmed Elaksher will complete working on the tide-coordination problem.

• Center for Mapping

• Tarig Ali will work on developing new methods for visualizing the quality of linear features. He will work on getting the transect erosion rates for Painesville to be used in his shoreline prediction system.

• SUNY at Buffalo

• Xian Xu will work on accessing data from the USGS website and making Ruijin's program access different data sources.

• Future Meetings:

• The next co-PI and RA meeting will be Thursday, January 16, 2003
• The next RA only meeting will be held Thursday, January 30, 2003
