Presentation Transcript

  1. Andrea Ryan Processing Coastal Lidar Data

  2. Nueces River Delta • “Persistently high salinity concentrations severely inhibit[s] the function of the Nueces Delta” (Dunton et al). • Data Collection for Model

  3. Lidar Data • Received Data – 1m x 1m grid Find coordinate system!

  4. Project Raster to 100m x 100m grid

  5. Rotating the Raster • Why rotate the raster? N 1m x 1m grids

  6. Rotating the Raster

  7. Larger Grid Size 100m x 100m grids

  8. Topography vs. Bathymetry Topography: Bathymetry: elevation data datum datum depth to sea floor *Datum is according to NAVD88 in this case *Datum is water level

  9. Combining Topo-Bathy The entire area is so flat it is difficult to tell where it is surface water & where it is land

  10. Coastal Lidar Mapping Applications Workshop • San Antonio: November 15th & 16th 2009. • Issues with specular reflection on marshy areas • Issues with wet/dry delineation • Issues with MetaData & QA/QC

  11. TCOON Data Texas Coastal Ocean Observation Network • Associate Time Series for: • Water levels • Wind Speeds • Wind Directions

  12. Precipitation Data

  13. Future Work • Collect salinity data from TCOON • Collect streamflow data from USGS • Meet with UT Center for Space Research
