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.
