Hi Guys,

I received a layer from source in a different coordinate system and need to convert/reproject the layer to my original layer's CS. Will be grateful if someone can guide me how to do this and provide the suitable reader,writer and transformers involved.

The readers and writers will depend entirely on your data.

The source and destination CS will also play a role in how to do the reprojection.

Can you give us some more information?

First read the data in the Data Inspector to check the Coordinate System.

Then (in FME Workbench) either set the Coordinate System in the Reader and Writer parameters to re-project automatically or use the Reprojector transformer to do the re-projection during the transformation.

Hi David, Thanks for reply. i'm trying to reproject from SVY21_Singapore_TM to PCS_Trnasverse_Mercator. The reason why i'm trying to do this is im unable to intersect this layer using STInteresects in SQL server but my source can only provide me with SVY21 CS. :(

 

Kindly help to suggest how to convert this.

Hi Erik,

 

Thanks for taking your time!

 

If I want to use Reprojector transformer. Is the below correct?

 

Reader--------> Reprojector----->writer

 

(Source CS) (target CS)

 

I tried the above but it doesn't work. Is the reader and writer format matters? If yes,what should be the correct one.

 

Will be grateful if you can help.

In broad terms that is the correct workflow, but some formats, KML for example, enforce a specific coordinate system. What format(s) are you reading and writing?

Hi ,

 

the format of my layer is SDE Feature class and i'm writing to same format.

 

what are the recommended reader,writer and transformers for this layer

You could try using the CsmapReprojector transformer. See also the answer from @erik_jan
