Overview

The Shoreline Tracer is an experimental application to create a (lat,lon) coordinate list of the shoreline in an aerial image. Using aerial images, a trained image classifier model, a start-point and direction on a shoreline, the app will follow the shoreline and will record the shoreline location (lat,lon) values at stepped intervals in a csv-file.

The Shoreline Tracer can download "GoogleMaps" satellite aerial images and save the images in a "Tile-Cache".

The Shoreline Tracer is an experimental application and is not guaranteed to trace all shorelines. However, I am making this program available, free of charge, in the event that it might be useful to others.

How it works

• In the main plot window, you select the shoreline image you want to trace at a Z-level magnification scale.
• You select an image training sampling and classification size.
• Using the plotted aerial images, you create a training image list of water samples, shoreline samples, and land samples.
• You then train the image classifier with the training samples.
• In the aerial image, you select a shoreline start-point and direction.
• You specify a tracing step size, an image scan range, and a scan step size.
• You then have the application start tracing the shoreline.

• The application will scan the aerial image in the start direction. The scan will produce Scanned Images at the selected image size and at the scan stepped locations. The app will record the angle to each 'Scanned Image' from the current location.
• The app will classify with probability values each image as water, shoreline, and land.
• From an analysis of the probability of the shoreline images, the app will determine the direction to the next point on the shoreline and will record the location (lat,lon) in a character-separated-value csv-file.
• The app will advance to the new location and will repeat the process.

The Shoreline Tracer will not necessarily trace the shoreline that you perceive as the true shoreline.

When the Shoreline Trace cannot find a shoreline, the application will stop. You can then add more training samples, retrain, and resume shoreline tracing.

Launch the program

1. When you launch the program, the program will display a disclaimer. Upon accepting the disclaimer, the program will continue to run; otherwise, the program will exit.
2. The program will ask for the location of the program's document folder. For a new installation, you can create the folder on any storage device and you can name the folder as desired (for example: Shoreline Tracer Data.)
