Grid Generation
Steps for Reprocessing Elevation Data
- Select the project horizontal and vertical datums and projections
- If necessary convert bathymetric/topographic input files to the correct projection and datums
- Checking dataset coverages
- Bring each bathymetric/topographic dataset into SMS
- If two datasets overlap select the dataset taken closer to the simulation period
- Delete the correct dataset in the overlapping regions
- Outlier removal
- If available, bring in aerial photographs or satellite images into SMS. This is very helpful for orienting and determining outlier points.
- Zoom-in to an individual dataset
- Set the contour color scheme for the scatterset to a narrow range so that outliers can easily be spotted.
- Delete outlier points
- Save individual datsets with a different name
