Kevin Cheng discussed differences between the GPS buoy and Marblehead tide-gauge data sets. The buoy was deployed for six hours while placed a few meters from the gauge station (see Appendix A ). He visited the gauge and mentioned that the gauge is just on the shore.

Ruijin Ma reported on his work with the ODNR permit system. He has finished the five functions required by the ODNR and the system now can now evaluate any structure based on these functions. He has started implementing the system with real data (see Appendix B ).

Chung-Yen Kuo reported on the differences between the T/P altimetry data, gauge stations, and TG-Geosat altimetry data (see Appendix C) .

Xian Xu reported by E-mail that he has been collaborating intensively with Niu on the program. He began using MapObject for Java that can be used to develop a java program, modifying the program to read Arc/Info coverage files. Currently he can only read in local files for Arc/Info coverage. Appendix D shows a screenshot of the program interface.

Xutong Niu gave a presentation on remote access to the spatial database (see Appendix F ). In it he summarized various methods for accessing the spatial databases on different servers. He briefed the group on the current status of the system he and Xian Xu are generating. He also reported that he is working on evaluating the shoreline differences and the differences between the DEM elevations and gauge station water levels.

Tarig Ali gave a presentation on the status of his work on the project (see Appendix G ). He is currently working on developing new methods for visualization of the quality of the linear features and studying their interdependency. He is studying the accuracy of shorelines generated by single photos and evaluating the potential for using shorelines digitized from single photos in his erosion awareness system.

Ahmed Elaksher reported on the water surfaces generated by the Great Lakes Forecasting Lab. He gave a presentation about the differences between these water surfaces (MHW, MLW, MMW). Xutong noted that he asked Rami about these surfaces, who said they are three-month averages (see Appendix H ). Xutong also showed the edited video for Tampa, which shows the area of sea grass on which the project team is going to work during the upcoming months.

Vasilia Velissariou reported that she has started looking at the Great Lakes Forecasting Lab database and will start calculating the statistical water surfaces (MLLW, MW, MHW). She mentioned that the lab data is now on the Internet.

Action List:

• OSU Mapping & GIS Lab
• Ahmed Elaksher will work on the tide-coordination problem.
• Ruijin Ma will start gathering Tampa Bay data (LIDAR, aerial photos, satellite photos, shorelines, etc.). Once the data is available, he will process it (triangulating the photos, digitizing the shorelines, extracting sea grass areas, etc.).
• Xutong Niu will work with Xian Xu on the remote access system (see Appendix E). He will also look for any differences between the DEM and the gauge stations and will work on analyzing the differences between different shorelines.
• Center for Mapping
• Tarig Ali will work on developing new methods for visualizing the quality of linear features. He will also study the potential for using single-photo digitized shorelines in his erosion system. Tarig will contact agencies in Painesville to obtain aerial photos and other geospatial data.
• OSU Geodesy Lab
• Kevin Cheng and Chung-Yen Kuo will work on assessing the different water surface data sets and see how they match.
• Hari Sugavanam will work on generating the ASTER DEM. He will also keep track of the request for the Lake Erie SRTM data.
• Great Lakes Forecasting System Laboratory
• Vasila Velissariou will familiarize herself with the Great Lakes Forecasting System Laboratory and its role in the project. She will provide two water surfaces: the 5-year and the 10-year Mean Lower-Low Water and Mean High Water surfaces. A grid with a smaller cell size will be required for Painesville.
• SUNY at Buffalo
• Xian Xu will continue generating the system for remote access to the coastal database infrastructure.

• Future Meetings:
• The next RA only meeting will be held Monday, January 6.
• The next co-PI and RA meeting will be held Thursday, January 16.

1. Given three kinds of data in three locations:

2. The program will be designed so that it:

1. Provides a function for configuring above data sources. Once data sources are added, they will be remembered by the program.
2. Add these three data sets into the map layer, and then display them.
