Tide-aware coastal mapping.
see1m combines seabed, shoreline and tide information into a single coastal map. The examples below show different coastal areas rendered using the same mapping and visualisation workflow.
What see1m does
Navigation layers
Display depth-based navigation layers using either the current tide or a lowest-tide reference.
Seabed mapping
Combine available elevation and seabed datasets into a continuous coastal surface.
Coastal projects
Apply the same workflow to individual bays, estuaries and coastal survey areas.
Live coastal examples
The examples below use the same viewer and processing workflow across different coastal environments and source datasets.
Torbay
Development area used for testing seabed mapping, tide-aware layers and shoreline visualisation.
