Python for clipping the area of interest

#1

Is there any python code to clip a study area in terms of the point coordinate positions (e.g., a rectangular frame)?

Thanks

I’m not sure if this is what you’re searching for, but please check snappy_subset.py in examples folder on your computer (~/.snap/snap-python/snappy/examples)

The answer to this depends on what you are trying to do. Creating a subset, as kedziorm might be the best approach in many cases. Does it help you?

What I would like to do through python is to give 4 coordinates of a rectangular area of interest, and extract it out of the entire image.

You can exactly do it as shown in the example kedziorm pointed to.
Insted of reading the WKT from the arguments you can directly use a string like

geom = WKTReader().read("POLYGON((15.786082 45.30223, 11.798364 46.118263, 10.878688 43.61961, 14.722727 42.85818, 15.786082 45.30223))")
