Coordinate systems transformations parameters

Hello,

I am having some problems with reprojection between two coordinate systems.

My data in some local coordinate system that is similar to MGI based EPSG:31276(same projection but different datum) and I want to reproject it to EPSG:32634(I have even made new coordinate system using

https://demos-safe-software.fmecloud.com/fmedatastreaming/Coordsys/Start.fmw?). I have transformation parameters but I don't know how to edit existing transformation files. I could really use some help if it is possible.

Important things: I have tried Reprojector,csmapreprojector but they are not giving me good result. I don't have ArcGIS installed so I am not able to use ESRI Reprojector.

Hi @maliodpalube,

You can find a complete description of the Transformation definitions at Adding a Custom Transformation.

The file FME\\Reproject\\MyCoordSysDefs.fme has several samples of custom transformations in it that you can copy/paste as a starting point for your own transformation definition.

If you run into any trouble, please send me the transformation specification, and I would be happy to help you out with a definition.

I have tried to add a custom transformation but it is not working as it should. I think FME is not even using my transformation. In csmapreprojector I can't set which transformation should it use, it is gray. Can You maybe help me?

I attached the MyCoord file and I will also write You here parameters of transformation.

Thank You in advance.

*Note: I have changed the extension to .txt just in order to be able to upload it to q&a; community. On my PC it is still .fme.

I have added the transformation, I needed to add it in LocalCoordSysDefs.fme in part of user defined but again when I run my workbench that only has one reader shp that is something similar to 31276 and csmapreprojector and shp writer in 32634 and when I click RUN, I am getting this error:

With localcoordsysdefs it works, but I am not sure why it is working now.
