I was just looking over the EXIF data template in EXIF.aspx and noticed that it will not get the Longitude and Latitude from a JPEG. I was wondering if this could be added.

Also is the EXIF data for a image stored somewhere? I know it is outputted to the module after you apply the proper settings at album level but if that EXIF data is being stored in a table and we could have a table for Longitude and Latitude then I believe we could very easily use google maps to geocode photos.

Please let me know what you think

the exif is retrieved in runtime.

if you are sure your picture contains other exif informations, you can open Exif.aspx, and add a new row like this:

[TR]
[TD class="SubHead"][asp:label id="Label28" Runat="server" resourcekey='ExifImageWidth'][/asp:label]:[/TD]
[TD class="Normal"]
[asp:Label id="lblExifExifImageWidth" runat="server"][/asp:Label][/TD]
[/TR]

Please note the lblExifExifImageWidth label means to display exif attribute "ExifImageWidth", so if your exif attribute name is "Longitude", you should write it in this way:

[TR]
[TD class="SubHead"][asp:label id="Label28" Runat="server" resourcekey='Longitude'][/asp:label]:[/TD]
[TD class="Normal"]
[asp:Label id="lblExifLongitude" runat="server"][/asp:Label][/TD]
[/TR]

Yes it seem many newer cameras will imprint GPS data into EXIF... but the read is at runtime so I guess this can not be easily exploited. being able to take just the longitude and latitude and save it to the DB, preferably in the 'Photo' table would be great...

the exif.aspx do read exif information in runtime, so the above solution should work as long as the attribute name is correct.
