Problem : Shapefile is not coming at right location whereas SID file is getting attached at right location. Is there any way where one can use the X and Y values from the SID image to attach it in the DGN File in the same location as the Shapefile?
Solution : The majority of the time this is caused by a units mismatch. Since you are dealing with three files, each of which can have its own units and coordinate systems, several things to try include:
- Compare and check the coordinate system stored in the SID file, with the coordinate system in the .prj file of the Shapefile, and if different make them the same and then try to load both files
- You should also check the Storage Units in the DGN file, and the Default Unit Settings in the DGN Workspace Preferences on the Georeference tab - many times changing this to/from meters corrects the problem
- You can also review the Sister File Settings at the time of attachment, and check the box to ensure that the complimentary coordinate system file is used, if the SID file has one
- And you should also ensure that the DGN file contains a valid Geographic Coordinate System. The image can also have a Coordinate System, which can be selected from the Library using the Raster Manager | Utilities menu
Reviewing these options and settings will ensure that your DGN file, the SID image, and Shapefile data all align and georeference properly.
