I have a polyline that I have reprojected in a new coordinate system. Before it was lines and arcs but after the transformation the arcs are many little lines. Is it possible to transform back this little lines in arcs?
Thanks

How to change a polyline with many little lines in a polyline with only lines and arcs
Hi,

Looks like the screenshot is not the View of FME Data Inspector.
View originalIf you have written the translation result into a certain format file to check the result, there could be a limitation in the format, rather than the reprojection itself.
Try connecting an Inspector to the ReframeReprojector so that you can check the result with FME Data Inspector.

Hi,
I think FME basically will not change geometry type during reprojection.
How did you confirm that the arc had been transformed into many lines?

Hi,
could it be that your arcs have been stroked (converted into polylines)?
If so, that is a semi-common problem with some transformations. My first suggestion would be to make sure that you use the absolute latest version of FME.
Also, make sure that you're using the right reprojection algorithm. The CsMapReprojector might be something to look into, if you're not using it already.

I'm using the transformer for the swiss coordinate system changement (ReframeReprojector).

Hi,
I agree with Takashi. At work we use the ReframeProjector extensively, and as far as we know it handles arcs without problems. In short, it is probably something else in your process that strokes the arcs into polylines.
