Summary

 

     Ruijin Ma reported that he worked on transferring his work to Ahmed Elaksher. He did show him the ODNR system, the data location, and the program framework. HE prepared a two page summary to explain the program framwork. He also transferred the IKONOS imagery and programs to Ahmed Elaksher. Ruijin worked on building a data warehouse for the project data, programs and documents.

 

    Xutong Niu reported that he is looking for a 3D visualization software to use in the data integration part of the project. He found a software named Java3D and start learning how it works and if it can be used in the project data integration. He also worked with Xian Xu on the program that he is developing. 

 

    Chung-Yen Kuo reported about the altimetry tracks in Tampa Bay (Appendix A). He found a number of tracks for the ERS-2 tracks in the Bay. However, the data is not completely calibrated. The data needs to be corrected for the IB and the Ocean Tide Model (can reach meters).

 

    Xian Xu reported that he started working on downloading certain geo datasets automatically when the user gives position. He has developed a program that can be used in downloading data from the webgis web page. 

The user has to specify the state, county, quadrant name then the program will list all available datasets within that quadrant. The user can then selectively download what he wants. The user can also give the position and all the data sets that intersects with this position will be selected and available for downloading. He also began working on linking his program with ArcCatalog.

 

Action List

• Center for Mapping:
  • Publishing the erosion awareness system and contacting the GIS department in Lake County to discuss with them the system and get their comments and suggestions on the system in order to improve it.
  • Visualization of the shoreline quality metrics (2-D and 3-D visualizations that combine the effects of all four metrics).
  • Developing a theoretical framework to study the spatial data completeness, temporal information accuracy, and attribute accuracy for linear features.
  • Implementing new applications for the spatial data completeness, temporal information accuracy, and attribute accuracy based on the developed theoretical framework.

• OSU Mapping and GIS Lab
  • Processing the aerial photos and satellite imagery for Tampa Bay.
  • Visiting the ODNR office and presenting the coastal structure permitting system in order to get comments and suggestions from the ODNR agencies and work on improving the system.
  • Integrating the ODNR system in the mobile wireless system.
  • Seagrass changes monitoring in Tampa Bay.
  • Completing the data integration work by including the shorelines, aerial and satellite photos, and DEM and using the system for the Tampa Bay dataset. 
  •  Visit NOAA's Office of Coastal Survey in June to get the water surface model software for Tampa Bay.
  • Publishing the ODNR system on the internet.

   

•  Great Lakes Forecasting System Laboratory

  ¡       Comparing the results of the altimetry data and the GLFS water model.

  ¡      Preparing the gauge station data and the meteorological data for the 20 years run.

  ¡      Running the GLFS model to obtain the 20 years mean, MLL, and MH water surfaces based on the results of the water surface comparison.

   

•  Laboratory for Space Geodesy & Remote Sensing

  ¡      Providing a water surface from the ERS-2 for Tampa Bay and comparing this water surface with the one generated from the tide gauge stations.  

   

•  SUNY at Buffalo:

  ¡       Xian Xu work on creating a browser in ArcCatalog interface to integrate his program with ArcCatalog.

   

§         Future Meetings:

    o       The next RAs only meeting will be Thursday, July 10, 2003.

    o       The next co-PI and RAs meeting will be held Thursday, July 24, 2003.
