You can use the Dissolver after the RasterCellCoercer, with the group by set to _band{0}.value



are they give me polygon ??

Ahh, you wanted to group the points instead of polygons. In that case, use the Aggregator instead of the Dissolver, and group by the same attribute. In your RasterCellCoercer, you will need to change the Output Cell Geometry from polygon to point.

No i want in polygon not points

Ok, so yes the Dissolver will dissolve the boundaries between like polygons, essentially grouping them. If you want to retain all the boundaries of the polygons, you could use the Aggregator.

i done as you said but its taking to much time to load data

Make sure 'Enable Feature Caching' is unchecked. Having this checked can drastically increase processing time.

i did but same result its take 30 mins to run the workspace and the around 45 mins to load the datat
