Abstract

This paper reviews the methodology and real world case studies related to deriving marine geospatial data, including bathymetric survey, seabed classification, and water quality monitoring from commonly available georeferenced imagery. The recent and planned launches of enhanced high resolution imagery satellites by government agencies and commercial operators is enabling broad area coverage with increased refresh frequency. Combined with a new approach and methodology for imagery analysis and processing called Modular Inversion Program (MIPS), these systems now enable rapid and cost-effective global marine geospatial data creation without the need to deploy equipment and resources. These data services enable a wide range of evolving applications including dredging monitoring, environmental monitoring of off shore construction, ecological status monitoring coastal zones, natural disaster risk analysis, algae bloom tracking, and fresh water quality monitoring. These new techniques and the impact on hydrographic surveying will be reviewed through a number of case studies including samples of project work delivered to the United Kingdom Hydrographic Office (UKHO), Geological Survey of Ireland (GSI), and GMES FRESHMON. In addition, the current and planned state of appropriate satellite imagery platforms and detailed review of the processing system components will be explored by this paper.
