Habitat Classification

Echosounder backscatter measurements of the bottom (whether seabed, lake bottom or riverbed) can provide information about the nature of that substrate (e.g. hard/soft, rough/smooth, sand/gravel etc.) and its bathymetry.

As the most flexible, integrated and transparent tool for bottom classification from single- and split-beam echosounder data, Echoview® enables you to:

  • Explore and calibrate your data
  • Account for noise and other artifacts
  • Define the bottom depth
  • Visualize and synchronize acoustic and video data
  • Identify and characterize the first and second bottom echoes (feature extraction)
  • Quantify and simplify the variance in the bottom features by Principal Component Analysis (PCA)
  • Cluster bottom points into classes by k-means clustering

Whether this information is used independently (unsupervised classification) or coupled with other environmental variables (supervised classification), Echoview provides a convenient yet powerful way to objectively describe the bottom and help to understand its role as habitat for aquatic organisms.
