Process_Description:
Data from multple sources was used to create grid. RIDOT, NOAA Lidar, RTK elevations, and bathymetry collected by URI Pedology Lab. Fathomether data were collected by URI Pedology lab using a GPS linked Garmin fish finder. All data were merged into a single data set. A TIN was created from the mass point and then exported and clipped to an ArcInfo GRID.
