I have a digital elevation model (DEM) with a point location defined.
I want to locate the lowest height values at a set distance from this point.
I envisaged creating a buffer around the point and then locating the lowest height values; firstly is this the best way of achieving this, if not can you recommend another option ?
If it is the best way, once the buffer is created around the point, how do I extract DEM cells with the lowest height values? I dont want to know what their values are, I want to be able to identify the cells and know where the cells are.
Thanks for any assistance you can provide.
