The types of metadata that you can edit depend on the output format that you select for an image.
Click the Edit Metadata button in the toolbar.
The Metadata Manager appears.
To edit user metadata, ensure that the User tab of the Metadata Manager is selected.
NOTE: Tag names cannot contain spaces, and tag values cannot be empty. Existing tags can be deleted but cannot be renamed.
Save the image's coordinate reference system in the metadata by clicking Select a Coordinate Reference System or entering a custom well known text (WKT) string in the WKT text field.
For more information on selecting a coordinate reference system, see Selecting a Coordinate Reference System.
NOTE: Selecting a coordinate reference system in the Metadata Manager does not reproject the image.
NOTE: Some existing JPEG 2000 images are encoded in such a way that certain decoders may fail to display them if you edit their metadata. To accommodate these images, GeoExpress handles several JPEG 2000 parameters in a special way. If you are editing the metadata of existing images and wish to change parameters for tile length markers, packet length markers, or tile parts, you must change them on the JPEG 2000 tab of the Preferences dialog. (For more information see JPEG 2000 Preference Options and Advanced JPEG 2000 Options.)
