How do you use GPS related to your pictures?

while I don''t have a use for gps info in my photos, and probably never will (see last poll answer - i''d rather not give out my location to anyone) ... I think its a good thing that gallery begin supporting it before any of the other photo services do.<br />
<br />
It would also be nice if gallery could generate a mini map of the world, like most gps enabled camera software, with links in the exact locations to photos taken in that area.

Personally I look forward to being able search locations by photos. I''d love to be to paste an address into a search engine and get back photos of it & it''s area.
<p>
I also enjoy being able to see my own photos laid out on a map, it''s gives more information to visual folks then a simple chronological listing.
<p>
To better support geotagging it would help if Gallery were able to read out the appropriate EXIF headers in a photo: <ul>
<li>Longitude
<li>Latitude
<li>Attitude
<li>City
<li>Sublocation
<li>State/Province
<li>Country
<li>Country Code
</ul>
<p>
With that information read it should be straight forward to embed it in a way search engines can find & use it. The two methods that seem most popular are header tags and wrapping the photos themselves.<p>

<pre>
[META name="geo.position" content="43.867703;-72.557144"]
[META name="geo.region" content="US-VT"]
[META name="geo.placename" content="South Royalton"]
<pre>
<p>
To wrap a photo in geo tags one popular style is the following (I expect it would fit inside the table code Gallery already has):
<p>
<pre>
span
43.86
-72.55
img
span
</pre>
<p>
Admittedly not every photo is going to be supplying the appropriate information in canonical format but even getting it sorta-wrong is fine as it also means getting it sorta-right, which is good enough for most search purposes.

Today Google announced their new <a href="http://maps.google.com/">mapping service</a>. They already do photo search and generate local searches. All of the search engines are rushing to do the same. With many Gallery users looking to share their photos explicitly supporting this seems an obvious feature.
<p>
A great free geotagging tool is <a href="http://www.wwmx.org/">World-Wide Media eXchange</a> (WWMX). From Microsoft Research it runs on Windows and uses their Map Point back-end to look up locations & addresses then embed their longitude & Latitude into a JPEG''s EXIF headers. They also host a photo sharing service for photos tagged thus.
<p>
Another great free tool turns tagged photos into web pages with maps: <a href="transmutable.com/93PhotoStreet/">93 Photo Street</a>. Java-based it automagically downloads & uses US Govt. maps for the county being mapped and provides a great example of what Gallery could eventually (down the road) do.

Finally, lots more resources can be found at <a href="http://locative.us/">http://locative.us/</a>.

Off web I use Memory Maps Navigator software which will link photos to map location and provide an icon on the map.
