I recently began geocoding my pictures as described in a post a couple days ago. However, I found that Flickr was not automatically placing my geocoded pictures on their Flickr Map upon import. I would have to re-input the data to Flickr after uploading.
But a few minutes ago, I found my solution on Jannis Herman’s Blog. It appears to be a somewhat hidden setting in Flickr’s interface. You can find the setting page for automatically extracting EXIF geocodes to the Flickr geotags here.
