moving a simple geo referenced jpg

KenLucas — Thu, 09 Mar 2017 15:56:55 GMT

When I attempt to move a simple, small, geo-referenced jpg image from one folder to another, using either ArcCatalog or Windows Explorer, and add the moved jpg to arcmap it fails to depict, giving me the message that it is un projected. I verified that the tiff comes in ok from the folder I initially saved the geo referenced work to and that both supporting .jgwx & .aux files are in the new folder along with the jpg

Is it possible to move geo referenced images?

How are you trying to add the copied jpg to the map document(add data, arc catalog, windows explorer, etc.)?

Also you keep mixing between TIF and JPEG in your original post, could you be a little more clear about what raster data type you are working with?

Couple of help links:

Ian,

Thank you for responding and I apologize for not being clear. I'm trying to copy a geo referenced JPG from one folder to another. I've attempted to use the Add layer button in a basic version of Arc 10.4.1. I'll read the help links now and respond back if they help.

The links,that Ian kindly posted above, helped me solve this challenge.

1. We should only use ArcCatalog, not windows explorer, to move geo referenced files from one folder to another.

2. Tiff images copy easier than JPG images.

3. I just tested to determine that this is the setting to allow the successful copying a geo ref JPG images, as provided in the 2nd of Ian's links:

ArcGIS will automatically read the geo referencing in the header information of some file formats, such as GeoTIFF, which will override any geo referencing information stored in a world file. You can change this by checking the Use world file to define the coordinates of the raster check box on the Options dialog box.

Click Customize on the Main menu and click ArcMap Options (or ArcCatalog Options, depending on the application you are using).
Click the Raster tab in the Options window.
Within the Raster tab, click Raster Dataset and check the Use world file to define the coordinates of the raster check box.
Click OKThank you, again, Ian,Ken
