Using non-satellite imagery about coastsat

[kvos]

hi @kcoastal1,
If you want to map shorelines automatically on aerial photographs, you may need to adapt the code so that it works with your new sensor (different format, metadata...etc).

One issue you may encounter is that on aerial photographs (which are usually only RGB) you may not have any infrared band, which are used in the shoreline detection algorithm currently implemented in CoastSat.

But you can use the same thresholding algorithm on another band, for example @mitchharley uses the Red - Blue colour space to automatically map shorelines on RGB images in his CoastSnap toolbox.
Here's a figure (Fig. 7) from his paper on CoastSnap (https://doi.org/10.1016/j.coastaleng.2019.04.003):

If you can integrate aerial photographs in the CoastSat workflow make a pull request as that would be much appreciated by the users!
