Grabbing GPS on Items to Map Locations

Another Boston Marathon Archive question. We recently batch-imported some photos that have GPS content in their embedded metadata, and we're trying to see if there's an easy way to get Omeka to read and map that content for us. For example, here's what the embedded metadata looks like for one image:

GPS
GPSLatitudeRef: N
GPSLatitude
42/1
20/1
5999/100
GPSLongitudeRef: W
GPSLongitude
71/1
4/1
3397/100
computed
latitude: 42.349997222222
longitude: -71.076102777778

We're using the Geolocation Plugin (2.01), and this particular image was added as part of a CSV import. I guess I'm just wondering if there's a way for Omeka to recognize this data and map it that doesn't involve individually adding it to the map for each photo (i.e. cutting out an additional step in the cleanup process for metadata).

We're using Omeka 2.0.3, if that helps.

The Geolocation plugin doesn't do that, mainly because of ambiguity about whether the embedded data would really correspond to the item's location.

That could be automated by a fairly simple plugin that goes through the items, looks for embedded data in the files, then adds a location from the latitude and longitude.
