Digital Shoreline Analysis System v5.1

The Digital Shoreline Analysis System version 5.1 software is an add-in to Esri ArcGIS Desktop version 10.4–10.7 that enables a user to calculate rate-of-change statistics from a time series of vector shoreline positions.

Marfac Machine Vision Camera Interface

This project contains the C# software developed to control and acquire imagery from a FLIR GigE machine vision camera. It is built using the FLIR Spinnaker 64bit SDK version and requires the spinview application and associated dll's. This software was developed using Microsoft Visual Studio 2019 to control and acquire imagery from a GigE machine vision camera (Model: BFS-PGE-50S5C-C, t

Multi-grid Analysis of Point Stability Tool

Elevation-change datasets can also be used to identify stable and unstable areas of the seafloor. The Multi-grid Analysis of Point Stability (MAPS) program was created to automate this process. This program is used to locate persistent areas of user-defined seafloor stability and/or instability at common geographic locations from multiple elevation-change datasets (grids) representing different ti

Seafloor Elevation Change Analysis Tool

The Seafloor Elevation Change Analysis Tool (SECAT) is a Python script intended to be run as a script tool by ArcMap or ArcGIS Pro that automates their intricate methodology.

Subaerial Barrier Sediment Partitioning (SBSP) Model Version 1.0

The Subaerial Barrier Sediment Partitioning (SBSP) model is a framework to simulate the morphological development of an idealized barrier coast in the cross-shore domain. The model code, built in MATLAB, consists of two scripts which must reside within the same folder when executed. The first, SBSP_InputControl.m, contains the user-defined input variables to run the simulation. The second, SBSP_Pr

Cliff Feature Delineation Tool and Baseline Builder, Version 1.0

The CFDT is an automated computer vision application designed to generate 3D line features representing the seacliff top, midpoint, and toe on high-relief coastal cliffs. The program also delineates 3D points on concavities and convexities across the cliff face (termed subsidiary features), which may represent talus deposits, secondary cliff tops, and secondary cliff toes. The tool package include


This software was developed for and used by the structure-from-motion (SfM) quantitative underwater imaging device with five cameras (SQUID-5) project. The SQUID-5's camera exposure and sensor gain settings are set identically using a program written with the Spinnaker SDK and examples. Another Spinnaker SDK based program was created to collect, format and save image data to long-term-storage wit

Coupled-Ocean-Atmosphere-Wave-Sediment Transport (COAWST) Modeling System

The Coupled-Ocean-Atmosphere-Wave-Sediment Transport (COAWST) Modeling System is an agglomeration of open-source modeling components that has been tailored to investigate coupled processes of the atmosphere, ocean, and waves in the coastal ocean.

COAWST Modeling System v3.4

Coupled ocean atmosphere wave sediment transport modeling system


This package is used to calculate coastal geomorphology variables along shore-normal transects. The calculated variables are used as inputs for modeling geomorphology using a Bayesian Network (BN).
