I am experimenting with an aerial raster over a river delta trying to find the fastest way to extract centre lines over the water ways.
Creating a point cloud with some sorting has resulted in a multipoint geometry that does a decent representation of the shore lines. Up until this stage the workspace is blazingly fast.
But in the next step it becomes painstakingly slow. I have tried both creating a hull around the multipoints as well as buffering them. The former was slightly faster but still very slow.
Are there other methods that might process faster?
