Good morning!

 

My input data is a series of 3D polygons that represent Administrative Units stored in an ESRI Geodatabase.

I've been tasked with calculating the area of those polygons. For that i wanted to use the AreaCalculator transformer with Type parameter as "Sloped Area".

No problems there. Except the final user of that data wants the area to be calculated using the Simpson's Rule. I had no idea what that was, so I've been looking for info a little bit:

I still don't know how to translate that to FME. Could anyone give me any pointers, please?

FME doesn't have a Simpson's rule function. However, 'R' does have a sintegral function that looks like it might be what you're looking for. You could then implement this in the RCaller transformer
