You can select the metadata standard you want to work with, set template options, specify the precision to which the metadata measures your map’s latitude/longitude values, and indicate whether or not you want the metadata for a data source to be updated as soon as you select it in the Metadata Viewer.
To set metadata options
Enter the number of digits (0 - 10) that display after the decimal point for your reported latitude and longitude values. Both values are 6 by default.
When Auto Update is selected, metadata is updated as soon as you select it in the Metadata Viewer.
