Portfolio extracts EXIF GPS metadata for use with the Map View functionality.
However, images may be missing this EXIF metadata, typically because the capture device does not have GPS, or the camera couldn't get a GPS signal at the time of the shot. This can happen sometimes, for example with photos taken indoors.
Configuring Portfolio for GeoTagging
Whilst EXIF GPS fields are 'read-only' and cannot be edited, it is possible to GeoTag images using XMP metadata. (Note: you should not do this for images that have correct GPS data). The XMP fields are already defined in Portfolio but by default are disabled. To enable them:
1) In Portfolio Administration, select your catalog under Catalogs, then select Fields.
2) Enable the XMP GPS fields as shown:
Formatting GPS for XMP
To add GeoTags, first identify the values for the location you wish to tag. Tools such as Google Maps, Google Earth and others can provide the values. Most tools provide values in the "DMS" format (degrees, minutes and seconds) along with directionality from the Equator/Prime Meridian. Altitude is provided as the height above sea level. For example:
Latitude - 54° 50' 54.08" N
Longitude - 2° 03' 14.91" W
Altitude - 245 m
However, XMP Metadata requires GPS to be in the "DDM" format (Degrees, decimal minutes) using a specific syntax. You can convert from DMS to DDM using mathematics, or more easily with one of many online calculators. For tagging in Portfolio the above values, converted by the calculator, should be entered as:
In Portfolio Web/Desktop, GeoTags can be added individually or in bulk using the syntax outlined above to asset types that support XMP metadata. To add the tags:
1) Login to Portfolio Web/Desktop
2) Configure your Metadata panel to show the XMP GPS fields, either by viewing 'All Fields' or creating your own view of fields.
3) Select the image(s) to tag, and enter the GeoTag values into the fields (as per above). On entry Portfolio will embed these values into the original asset.
4) Delete the asset record from the catalog, ensuring you DO NOT DELETE the original file itself!
5) Recatalog the file (typically automatic if using an Autosync watch folder).
You should now see DMS values in both the XMP GPS, and EXIF GPS fields and see the location in the Geo-Map field in Portfolio.
Once completed the XMP GPS fields may be disabled in Portfolio Administration, if there is no more requirement to add GeoTags going forwards. This is advisable to avoid accidental edits.
