ArcGIS Pro Transformation Parameters

[MohammedElsayed1]

I have 2 questions..

1- When adding a feature class or any dataset with different geodesy into ArcGIS Pro, How to select the transformation parameters that will be used. Like in ArcGIS desktop a window appears with a list of transformation parameters to choose from it. but in ArcGIS Pro nothing appears to choose from and it makes different transformation than I want.

2- Also when i use the Append tool to add data from a feature class that has a different geodesy than the one I add to it choose a transformation parameter by default which is not the one I want (For example, Egypt_1907_To_WGS_1984_4 instead of Egypt_1907_To_WGS_1984) , so how to choose or change the transformation parameters in the Append tool.

Thanks

1. Look at the projection on the fly section here Projection on the fly and geographic transformations (esri.com)

2. Not sure

Hi @MohammedElsayed1 

Regarding your second question; 

I would suggest using the Project tool to transform, using the transformation of your choice to the data before appending.

If the spatial references of an input and target feature class do not match, the Append tool will project the features in the input feature class to the coordinate system used by the target feature class. It seems that this is your problem.

Hope this is helpful.

Thanks for your reply

I was aiming to reduce the steps but it seems like it is the only way to do

Thanks all, it is solved..

I have to set the transformation parameters for the map before using the Append tool
