phTagr supports now Google Maps and RSS feeds! Click here for a demo of the Google Map integration. To enable Google Maps you have to set the Google Maps key in Preference/System from the admin account.
The geo meta data is extracted from new images using Exif tags GPS Latitude and Longitude. I have written a small PHP tool gpssync (available here) which extracts the GPS position of an NMEA file (e.g. from the GPS tracker Sony GPS CS1). It estimates the position by linear interpolation and saves the GPS position using exiftool. Call “./gpssync.sh -g WG20080504135002.log *.jpg” to synchronize the geo positions to your images.
The phTagr image explorer provides now a RSS feed for new (public) images where users can subscribe to it to be informed about new images automatically. You can add the RSS feed (found here) to your favorite RSS reader (e.g. Thunderbird) and wait for new published images. You never need to visit the gallery again to check for new content!
