Hi,
I have a workspace that uses some RasterToPolygonCoercer, but the performance is very low.
I need to improve the performance. I'm trying to convert some clouds detected in my raster image into polygons.
How can I improve that?
Thank´s

PolygonToCoercer very slow

Converting to the polygons can be quite slow as you detail. But you could also go out to points and rasterise the points based on the cell spacing of the input raster cells.
I did it slightly different with this example, utilsing a pointcloud approach and extracting white (255,255,255). Sorry, you get a picture of me from almost 10 years ago, but you will get what I am trying to do.

You could split your image into tiles and do some parallel processing by creating a custom transformer.
