  • I have a large dataset of geometries that are touching multiple other geometries. I would like to use the four colour theorem to isolate areas that do not touch. How can this be done in FME? Should I be using the feature colour setter?

As a note, we can do this in QGIS using the Topological colouring.

Hi @ejmt​ 

 

You can use the transformer SpatialFilter to do a spatial relator beetween the geometries. After you can use the transformer TestFilter to isolate the colors that you want by fme_color or another attribute of color that you have.

 

 

Thanks in Advance,

Danilo
