Shoreline and coastal bathymetry mapping over time

Satellite imagery is used to map dynamic coastal environments and quantify shoreline and bathymetry changes over time. By analyzing historical and current satellite imagery, this service identifies critical patterns of erosion and accretion, providing information needed to plan projects, protect infrastructure, and manage natural resources. From detecting subtle seasonal shifts to documenting long-term coastal retreat, satellite-driven coastal monitoring offers a scalable, objective view of the coast. In addition to shoreline and bathymetry mapping, benthic habitats and water quality can also be monitored from space and included with this product. 

Value Proposition

Provides a scalable and objective record of shoreline and bathymetry changes over time, supplying the critical intelligence needed to protect infrastructure and manage natural resources.
