I have a big raster file (129600 by 64800 pixel) with global water bodies (1 bit values 0 and 1) and try to extract ocean and inland water shorelines.
I've tried with ArcGIS and QGIS to convert from raster to polyline, but it takes ages.
Does anybody know a better/faster way (Python or R) or a better tool for this task?
