Location Formats

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 <meta name="ICBM" content="XXX.XXXXX, XXX.XXXXX"> [1]

GeoUrl

Geotagging

  • Geotagging has been employed in delicious, flickr,

Flickr Geotags

A2B

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 pinged. They support lat/long and ICBM meta tags.

RSS

Several people have tried putting geographic information into RSS.

  • This site uses icbm coordinates and has plugins for several blogging packages.
  • BlogMapper - appears to be adding a namespace to RSS.
  • BlogMap - picks up RSS extension and meta tag values
  • worldKit RSS docs - worldKit advocates and understands various flavors of geocoded RSS; particularly the "geo" namespace.
  • USGS earthquake feed - most widely used geocoded RSS feed

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.

Plazes

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

Semantic Web

GML

Geographic Markup Language
