Summary:
Xutong Niu reported that:
1- He obtained the data descriptions from Ahmed that explain the sources
of the data used in the DG project.
2- He tested the remotely-access database program from Xian.
3- He visited the USGS Tampa Bay project web page.
4- He suggested building a web page for our current data and arranging
the data so that it can be easily accessed and can be used as an example
for government agencies.
Tarig Ali mentioned that he visited the USGS web page for Tampa Bay project.
He suggested the following research topics be discovered:
1- Sediment plume mapping.
2- Water vapor mapping.
3- Sandbar detection from high-resolution satellite.
4- Tide direction mapping.
Ruijin Ma reported that he has finished the five functions for the ODNR
permit system. He gave a presentation about his view of the project (Appendix
A).
Xian Xu reported by E-mail that in the last two weeks he has programmed
the basic structure of the multisource display program (see Appendix B).
He has also designed the data display program. The program is now capable
of the following:
1- Display maps from local files using MapObject. Thus files must be
in ESRI format. Currently the program wouldn’t attempt format conversion.
2- Some geo-operations including zoom-in, zoom-out and panning.
3- Map layer control including rename a layer, change layer visibility,
change layer order and color, delete a layer, and change layer names.
Chung-Yen Kuo reported by E-mail that:
1- He has found ERS2 tracks in the Bay, and he generated a grid data
of (0.0625o*0.0625o) using both the ERS2 and T/P altimetry data (see Appendix
C).
2- He compared the OSUMSS95 model and the ERS2 mean sea surface at the
ERS2 bin center. Mean for the difference is 0.0281 with std 0.0650 m. This
means mean sea surface changes about 3 cm in this area. This value is smaller
than our required accuracy (10 cm).
3- He requested tide-gauge data for the station located at the coast in
open sea.
4- The G99BM model is still unavailable.
Hari Sugavanam reported by E-mail that:
1- He sent a proposal to Dr. Michael Kobrick for SRTM data in
Lake Erie.
2- He downloaded SAR data for Lake Erie that includes the following areas:
latitude:42-41N and longitude:80-81W,
latitude: 42-41N and longitude: 81-82W, and
latitude: 42-41N and longitude: 83-84W
Kevin Cheng reported that he gave Ahmed the GPS instruments to be used
in Tampa Bay.
Action List:
- Ahmed will
- Work on the tide-coordinated shoreline.
- Ask Chung-Yen for the original altimetry data before interpolation
and send to Xutong.
- Arrange the Tampa Bay visit.
- E-mail Zhong Lu to see if he can join us in Tampa Bay USGS
meeting.
- E-mail co-PIs to notify them of the next project meeting.
- See what water surfaces we generated and compare the dates
with the project minutes to see when they were generated.
- Ask Chung-Yen to join us in the next meetings and give the
DG presentation.
- Ruijin Ma will
- Check the vector shoreline from CSC for Florida and get it
if available.
- Check the metadata for the raster T-sheets for Tampa Bay.
- Check the water surface data provided by Sean and send the
file format to Takis.
- Compare LIDAR data with the CTM.
- Xutong Niu will
- Work on integrating different data sets and see how they match.
- Send Xian comments and suggestions for the Internet development
program.
- Design the web page for the database arrangement.
- Center for Mapping
- Tarig Ali will work on the Kalman filter modeling for shoreline
change detection.
- OSU Geodesy Lab
- Kevin Cheng will work on the GPS ground control points.
- Chung-Yen Kuo will
- Look for more gauge stations in the area.
- Find the G99BM model.
- Work on the Tampa Bay water surface analysis.
- Prepare a presentation for the next meeting.
- Hari Sugavanam will
- Work on generating the ASTER DEM.
- Keep track of the request for the SRTM data for Lake Erie.
- Great Lakes Forecasting System Laboratory
- Takis Velissariou will familiarize himself with the Great Lakes
Forecasting System Laboratory role in the project.
- Xian Xu will continue working on generating the remote access
to the infrastructure coastal database. He has to stop working on MapObjects
and concentrate on Internet download and data conversion and data overlay.
-
Future Meetings:
- The next RA meeting will be held Thursday, November 14
- The next co-PI and RA only meeting will be Thursday, November
21
