= Location Formats =
__TOC__
This is a list of previous efforts at location / geographic ("Geo") data formats and protocols, as background research for developing a location format.

== vCard & hCard ==
vCard (RFC2426) and [[hcard]] includes 'adr', a way to markup addresses. There is also a field called 'geo' for lat/long.

== ICBM ==
Comma seperated list of lat/long <code><meta name="ICBM" content="XXX.XXXXX, XXX.XXXXX"></code>
[http://www.catb.org/~esr/jargon/html/I/ICBM-address.html]

== GeoUrl ==
* [http://geourl.org/ GeoURL]

== Flickr Geotags ==
* [http://steeev.f2o.org/mt/2005/05/geotagging_flickr_with_google_maps_and_greasemonkey_part_2.html Flickr GeoTagging] A Greasemonkey script for adding lat and long tags to flick pictures. He uses Google Maps to get the lat and long. Users have to enter search terms (address, etc) and then select a point on the google map. Photos are tagged with "geo:lat=xx.xxxx", "geo:lon=xx.xxxx" and "geotagged" and aggregated at [http://geobloggers.com/]
* [http://flickr.com/groups/94823070@N00/ A Flickr Group related to the topic]
* [http://txfx.net/2005/05/17/flickr-google-maps-geobloggers/ A visual walkthrough of the technique.]
* As of today (2005-06-01), 14k photos have been geotagged on Flickr.
* [http://mappr.com mappr], [http://brainoff.com/worldkit/flick mapping flickr] also support these geotags.
* flickr also supports [http://www.flickr.com/services/api/flickr.photos.getExif.html EXIF headers], which can be used for storing location.

== Geotagging ==
* Geotagging has been employed in other hosted services: [http://brainoff.com/worldkit/delicious/ delicious], [http://worldkit.typepad.com/ Typepad], [http://blog.360.yahoo.com/blog-yRZQpvY8cq2kWXBO5ZrxEmrwsg--?p=9 Yahoo 360]

== A2B ==
[http://www.a2b.cc/ A2B] is a location based search engine. Lat and long only. Seems to pick stuff up from geo meta tags. Pages can either be manually entered or [http://www.a2b.cc/help-searching-addurl-blogping.a2b pinged]. They support lat/long and ICBM meta tags.

== RSS ==
Several people have tried putting geographic information into RSS.
* [http://postneo.com/icbm/ This site] uses icbm coordinates and has plugins for several blogging packages.
* [http://www.blogmapper.com/ BlogMapper] - appears to be adding a namespace to RSS.
* [http://www.feedmap.net/BlogMap/ BlogMap] - picks up RSS extension and meta tag values
* [http://brainoff.com/worldkit/doc/rss.php worldKit RSS docs] - worldKit advocates and understands various flavors of geocoded RSS; particularly the "geo" namespace.
* [http://earthquake.usgs.gov/recenteqsww/rss.html USGS earthquake feed] - most widely used geocoded RSS feed
* [http://brainoff.com/worldkit/doc/polygon.php Polygons and lines in polygons] - A simple format for expressing polygons and lines is defined for worldKit

== Address2Coordinates ==
Both of these systems are freely available sources of address to lat/long mappings (US only). I think they're based on US Census data, so they might be up to date.
* [http://www.census.gov/geo/www/tiger/ TIGER]
* [http://www.itl.nist.gov/fipspubs/55new/nav-top-fr.htm FIPS]
* [http://geocoder.us/ geocoder]
* You can get coordinates from UK post-codes from [http://www.streetmap.co.uk streetmap]
* Worldwide city level location data (over 4 million entries) is available from the [http://earth-info.nga.mil/gns/html/ GNS]. This is accessible as a REST service from the [http://brainoff.com/geocoder/ worldkit geocoder]

== Plazes ==
[http://plazes.com Plazes] is a system that does geo-info based on the network access point that the user's computer is connected to. They use tagging to identify locations.

== Mapping Sites ==
* [http://www.multimap.com Multimap]
* [http://maps.google.com Google Maps]
* [http://www.mapquest.com MapQuest]
* [http://maps.yahoo.com Yahoo Maps]

* [http://esw.w3.org/topic/GeoOnion GeoOnion] - a SW vocuabulary for relating items by distance from each other.
* [http://www.mapbureau.com/rdfmap1.0/index.html RDFMap]

[http://www.a2b.cc/ A2B] is a location based search engine. Lat and long only. Seems to pick stuff up from geo meta tags. Pages can either be manually entered or [http://www.a2b.cc/help-searching-addurl-blogping.a2b pinged]. They support lat/long and ICBM meta tags.

== RSS ==
Several people have tried putting geographic information into RSS.

== Address2Coordinates ==
Both of these systems are freely available sources of address to lat/long mappings (US only). I think they're based on US Census data, so they might be up to date.

__TOC__
This is a list of previous efforts at location / geographic ("Geo") data formats and protocols, as background research for developing a location format.

== vCard & hCard ==
vCard (RFC2426) and [[hcard]] includes 'adr', a way to markup addresses. There is also a field called 'geo' for lat/long.

== ICBM ==
Comma seperated list of lat/long <code><meta name="ICBM" content="XXX.XXXXX, XXX.XXXXX"></code>
