Upon ArcMap data layer Reprojection, data is not lining up

[tmo]

Hello all, 

Like the title says, my data will not line up after reprojecting into the coordinate system I am trying to match with another.

I have an existing layer called AA_Cities and a newly downloaded shapefile called LA_County_Boundaries2022. 

AA_Cities is currently in NAD_1983_StatePlane_California_VFIPS_0405_Feet.

LA_County_Boundaries2022 is being reprojected from WGS_1984_Web_Mercator_Auxiliary_Sphere to NAD_1983_StatePlane_California_VFIPS_0405_Feet.

CITIES (existing)

LA County Unincorporated Boundaries 2022 (downloaded shapefile)

Reproject_22laco_unincorporated_boundaries (Reprojected Layer)

Data Not Lining Up

Could you try a different transformation method, like "NAD_1983_To_WGS_1984_5"?

Transformation methods are bidirectional (works both ways).

Hi Jayanta thank you for this info it is good to know. I tried your suggestion and the data doesn't seem to move at all. I have tried several transformations and followed the suggestions of the table listed below to no avail.

shot in the dark here: Make sure your data frame coordinate system is defined as NAD_1983_StatePlane_California_VFIPS_0405_Feet
