Sea Turbidity Monitoring with Satellite Imagery

0

Today, we are highlighting news from Planetek Italia, a channel partner who provides Hexagon Geospatial Solutions in Italy.  The company recently announced that very high resolution satellite images can effectively support the monitoring of water quality during dredging activities for the installation of new off -shore infrastructures.

This innovative approach in water quality monitoring has been adopted by Saipem S.p.A, an Italian oil and gas industry contractor, subsidiary of Italian energy company ENI, which has contracted for designing and constructing several pipelines all around the world.  The new approach integrates traditional analysis methods with daily collections of high-resolution satellite images over the area of interest. Automated workflows designed with the Spatial Modeler in ERDAS Imagine provide, within a few hours from the satellite collection, accurate and validated information, useful for the quantitative and spatial definition of the entity the phenomenon of dispersion of sediments during dredging operations.

The processing models designed by Planetek use several operators (e.g.: atmospheric correction, conversion from digital number to reflectance, up to the estimation of the turbidity of the water measured in NTU – Nephelometric Turbidity Units) in order to streamline a workflow that, starting from the raw satellite data, provides a final product ready to use. The spatial modeler ensures the fast production of standardized products, which is essential when real-time information are needed.
