cBathy User Manual

Welcome to the cBathy User Manual, a source for information to get you estimating bathymetry. The cBathy processing code can be found here. Click the links below for more information. Edit as necessary.

1. Introduction

2. Background

   This section describes background about the complications of bathymetry estimation from optical sensors and the principles adopted by cBathy.

3. cBathy Algorithm

   This section is split up into multiple sub-sections:

   1. Sampling Array

      This section describes the principles for design of cBathy's sampling array and analysis design.

   2. The bathy Structure

      This section discusses the three phases of analysis and the corresponding nature of the bathy structure that is the output by cBathy.

   3. The Process Error

      This section describes the process error that is required for Kalman filtering during the runningAverage calculation. A process error function should be developed or calibrated from the existing location specific function before the Kalman Filter component of the algorithm is run. For example in Duck, NC, process error is a calibrated function of the offshore wave height and a grid-nodes cross-shore location.

   4. The Settings File

      This section discusses the settings file that is used to configure the analysis for any new site.

   5. Parallel Processing

      This section gives a short note on using cBathy with a parallel processing version of MATLAB.

   6. Debugging

      This section contains a lengthy description of debugging support in cBathy.

4. Appendix A

   This section contains an example pixel collection m-file.
