{PING-Mapper is a Python interface for reading, processing, and mapping side scan sonar data from Humminbird® sonar systems.}
Transform sonar recordings...
Video made with HumViewer
...into scientific datasets!
Running main.py (see this section for more information) carries out the following procedures:
-
Decode Humminbird® (tested on 1197, 1198, 1199, Helix, Solix, Onix). If it doesn't work for your Humminbird® recording, submit an Issue. For more information on Humminbird® recording file formats, read the docs.
-
Export all metadata from .DAT and .SON files to .CSV.
-
Automatically detect depth (i.e. Zheng et al. 2021) and shadows in side scan channels .
-
Correct sonar backscatter with Empiracle Gain Normalization.
-
Export un-rectified sonar tiles with water column present (WCP) AND/OR export un-rectified sonograms with water column removed (WCR) using Humminbird depth estimates OR automated depth detections.
-
Export speed corrected un-rectified sonograms.
-
Smooth and interpolate GPS track points.
-
Export georectified WCP (spatially inaccurate due to presence of water column) AND/OR WCR sonar imagery for use in GIS w/wo shadows removed.
-
Mosaic georectified sonar imagery.
-
Automatically segment and classify substrate patches.
