This code has been developed to facilitate rapid and automatic mapping of former subglacial meltwater pathways (hummock corridors) on palaeo-ice sheet beds. It uses a series of image processing techniques to isolate hummock corridors from their background relief. The resulting map can be imported into a GIS and overlain on high resolution digital elevation data to explore the large-scale spatial distribution and morphological characteristics of these features.
