I have two shape files, with the same coordinate system (File 1 and File 2).
I have defined the Projection/Coordinate System of File 2 in ArcGIS using ArcToolbox using the Data Management Tools/Projections and Transformations/Define Projection.
For selecting the coordinate system. I have used the import button and have it use the same coordinate system of file 2.
Everything seems right the current coordinate system of both files is the same, but the files don’t align /overlap. What is wrong with these files? The only strange thing that I find is the Units that in both cases are “Unknown Units”.
The data source box of both files is the same :
