How to stop RasterToPolygonCoercer from aggregating cells into larger polygons when neighboring cell values are the same?

It seems that by default that RasterToPolygonCoercer transformer joins polygons if they have the same value as the neighbouring cell, as seen below:

 

 

And there seems to be no option in the RasterToPolygonCoercer to stop it from doing this.

 

 

What is the simplest way I can fix or avoid this aggregation of cells to larger polygons - either by using a different transformer(s) to coerce the raster, or by further processing the polygon output?

Hi,

 

 

You can use the RasterCellCoercer transformer to transform a raster into individual cell polygons. Set "Polygons" to the "Output Cell Geometry" parameter.

Why not inspect features with Visual/Data Preview and Feature/Record Information before writing them into a destination dataset?

ah yes, I forgot about the RastercellCoercer! Thanks!
