Résumé(disponible en anglais seulement)
Following the public release of SIPS Backscatter, a new algorithm for processing multibeam backscatter imagery, Teledyne CARIS has continued investment in this approach to provide reliable backscatter mosaics that can be used to support a variety of seabed mapping tasks. A common need for seabed mapping includes seabed classification, by processing multibeam time series, beam average and multi-spectral data. Defining areas on the ocean floor with similar characteristics is a complex task involving several variables beyond pure sonar reflectivity: it is common practice to also define underwater environments using delineation parameters such as water depth and slope. With that in mind, CARIS HIPS and SIPS are currently able to provide a single high resolution raster product containing depth, slope, and intensity. In terms of seabed classification, this raster can be used as input to create acoustic classes based on the combination of layers such as depth, uncertainty, slope, aspect and intensity.
