SWT

The Spatial Wavelet Transform of J. K. Hillier (2008) Seamount detection and isolation with a modified wavelet transform. Basin Research 20, 555-573. https://doi.org/10.1111/j.1365-2117.2008.00382.x

Compilation

A Makefile is provided to compile the code on Unix systems. Download the code repository and run make from the SWT/ directory. Two executables will be produced:

• swt: computes the spatial wavelet transform on a provided profile
• find_seamounts: estimates seamount morphology from depth profiles filtered by swt

Usage

See the Makefile for usage examples.

Testing

Snapshot characterization tests are implemented using an example provided by Yuezhi Zhong. Run

make check

from the SWT/ directory to run the tests. The input data is run through the executables and then compared to output that has previously been generated by the program. Any discrepancies will cause this program to fail with a nonzero exit code and to print out the mismatched data.
