OSU Center for Mapping: Alok Srivastava
Summary:
In this meeting, Xutong summarized the progress of the project
(Appendix A):
1. Site: Lake Erie
Data. Most the data have
been collected and processed. Two kinds of data are left. One is 10 –
19 year water surface generation.The other is Lidar Survey along the
Sandusky shore. SRTM data datum conversion needs to be finished.
Data Comparison. Comparison
between altimetry and water surface model along two short tracks should
be finished soon.Then the absolution comparison between altimetry and
the water surface model should be finished (comparing three-year
average only at the spot of altimetry data).
Systems.
- The web-based ODNR system is being developed by Xian Xu and
Xutong Niu. 2D and 3D is under development. It will be ready for
testing before Thanksgiving.
- 3D visualization system: top-view and side-view profile should be
added into the system.
- Erosion Awareness System. The query for influenced parcels is
being added into the system based on ArcIMS. This system should be
refined for publication.
Tide-Coordinated Shoreline Model.
More work should be added into the model development.
2. Site: Tampa Bay
Only data issues were discussed for
Tampa Bay site.
- Altimetry data: The Geodesy Lab will look in their
archives to manually select useful Tampa Bay altimetry data, including
ERS and new T/P. However, no tide correction information is available
for the area inside Tampa Bay.
- Water gage data: ready.
- Water surface modeling: No one is doing this right now.
- DEM: USGS DEM is ready. DEM from aerial photos and QuickBird
data need to be extracted. SRTM DEM is available and Chung-yen will do
the datum conversion.
- Shorelines: 3D shorelines from aerial photos and QuickBird data
need to be extracted.
- Orthophotos: USGS DOQQ is ready. Orthophotos from aerial photos
and QuickBird data need to be extracted.
Action List:
- OSU Mapping & GIS Lab
- Xutong Niu will make modifications to the 3D display system and
use it in both the ODNR system and 3D uncertainty visualization.
- OSU Geodesy Lab
- Chung-yen will do the datum conversion for SRTM data and
prepare the document for data comparison.
- OSU Center for Mapping
- Alok Srivastava will work on the parcel query function for the
ODNR system.
- Great Lakes Forecasting System Laboratory
- Vasilia Velissariou will do the data comparison along the two
short tracks and then work on the absolute comparison between altimetry
and water surface based on three-year averages with NAVD88 datum.
- SUNY at Buffalo
- Xian Xu will keep working on the ODNR System, prepare user
instructions, and make it ready for testing.
- Future Meetings:
- The next RA meeting will be on Thursday, November 25, 2003.
