Problem: Feature classes exported from XY data layers with null coordinate values have zeros as coordinate values
In ArcMap XY data can be exported to a shapefile, or as a feature class in a geodatabase. If the coordinate values for some of XY data records are blank, that is the X or Y values are null, and you export to a shapefile, the exported shapefile will contain points with coordinate values of zero.
This is a known issue.
Solution or Workaround
Exclude XY data records with null coordinate values when exporting to a shapefile. You can export null records to a personal geodatabase.
- Open the XY data table.
- Select all the records containing valid X and Y coordinates, that is values that are not null.
- Export the selected records to a shapefile.
