Tidal Range Points

File Geodatabase Feature Class

Tags
tides, tide range


Summary

Created primarily for SLAMM modeling because the model requires the great diurnal tide range as an input.

Description

These points show tidal range at various locations on the Virginia Eastern Shore. Some points represent NOAA tide gauges and were downloaded directly from the NOAA Tides and Currents web site. Additional points were modeled using NOAA's VDATUM software.
