Hi All,

 

I’m trying to dissolve thousands of polygons from different feature classes into a single shape in FME. The idea is to obtain a single external boundary after merging/dissolving all the polygons. The current dissolve transformer gives me an error while trying to dissolve the polygons.

Parameters in the dissolver are set to default.

Is there any ‘hard dissolver’ option to merge the following?

 

 

Thanks :)

I do this stuff using the HullAccumulator.

Thanks ​@nielsgerrits  - I have just tried the HullAccumulator but it gives me a broad outline, see below:

...I would need something more accurate.

You will need to tweak the Alpha value. Please see the documentation.

That’s brilliant - yes, I have set up the Alpha Value to 10 and has done the trick. thanks a lot :)
