Save Image Metadata from Camera Images

The installed app automatically saves the time stamp and GPS coordinates in the metadata of the images taken from the camera in iOS and Android native apps. Both coordinates are stored in the metadata of the images in the EXIF format.

	Android	iOS
Browser application	No limitations	Limited ability to store GPS coordinates
Native application	No limitations	No limitations

Note: Due to the limitations imposed by Apple, you cannot collect GPS coordinates for an image while using the Oracle Fusion Field Service Browser application on an iOS device. However, there is a way to collect geo-coordinates in the metadata of the images for the browser applications running on iOS. You can take an image using the camera, save the image in the gallery, select photos from the gallery and attach them to a form.

• Timestamp Metadata

  The timestamp is always saved in ISO format with the UTC zone offset for all the images taken from a camera. You can obtain the timestamp from these metadata tags:

  • DateTimeOriginal: Date and time when the original image was taken.

  • DateTimeDigitized: Date and time when the image was stored in .

  • OffsetTimeOrigin: Time zone of the original date and time.

  • OffsetTimeDigitized: Time zone of the digitized date and time.

• GPS Coordinates Metadata

  Enable these functions on your mobile devices to save the GPS coordinates in metadata:

  • Enable the Geolocation setting in General settings.

  • Enable the Location setting in Camera settings.

  You can obtain the location from these metadata tags:

  • GPSLatitudeRef: Indicates whether the latitude is North or South. The ASCII value 'N' indicates north latitude, and 'S' is south latitude.

  • GPSLatitude: Indicates the latitude. The latitude is expressed as three rational values as dd/1, mm/1, ss/1. When degrees and minutes are used, for example, fractions of minutes are expressed up to two decimal places, then the format is dd/1, mmmm/100, 0/1.

  • GPSLongitudeRef: Indicates whether the longitude is east or west. ASCII 'E' indicates east longitude and 'W' is west longitude.

  • GPSLongitude: Indicates the longitude. The longitude is expressed as three rational values as ddd/1, mm/1, ss/1. When degrees and minutes are used, for example, fractions of minutes are expressed up to two decimal places, the format is ddd/1, mmmm/100, 0/1.

Follow these steps to save image metadata:

1. For Android users:
   1. Open the Camera app.
   2. Tap Setting of the camera app.
   3. Enable the Location tag or Save location option.
2. For iOS users:
   1. Open Settings and go to the Privacy option.
   2. Enable the Location services option.
   3. Tap the Camera option and select While Using the App option.

What to do next

Note: Location and timestamp are integral to images. You can use a Core API to download images to external applications and retrieve this information from the metadata. If you're using Oracle Field Service, you can use Daily Extract. Currently, Oracle Fusion Field Service doesn't display this information in the UI or provide it separately through public APIs.
