Compound Curve problem

Hello!

 

 

I am trying to convert COMPOUNDCURVE to FME_line but the GeometryFilter transformer wont recognize COMPOUNDCURVE as an ARC :( I am managing a PostGIS database and i found a temporary SQL-fix: http://www.postgis.org/docs/ST_CurveToLine.html (http://www.postgis.org/docs/ST_CurveToLine.html)

 

 

Any ideas? :)

 

 

 

Best regards,

 

AlexG

Hi,

 

I think you will have to deaggregate the feature first.

Hi,

 

 

The GeometryFilter seems to treat a composite curve like the COMPOUNDCURVE as a Line geometry, even if every component is arc.

 

If you send the feature to Data Inspector, what kind of geometry type is detected?

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

I have tried using 2DForcer --> Deaggregator --> GeometryValidator --> Intersector and GeometryValidator in an array. GeometryFilter --> GeometryCoercer won't work either. I don't know exactly which object that is failing becaus i generate the PK when i do the DB uppload. I have 1372106 features and 12 Compound Curve ;P

I would try the TopologyBuilder > GeometryFilter, any improvement?

As Takashis said, its not a compositon of (solely) arcs. The compound curve will be treated as a fme_line.

 

So you should see the cc output at the line output of the Geometryfilter.

Ok, this confirms my suspicion about the GeometryFilter :P I will try the TopologyBuilder :)

you could expose the attribute and test on the fme_type.

 

Look in the navigator wich attribute to expose (or use directly)
