  8. 8. What is Geotag? <ul><li>GeoTagging , sometimes referred to as Geocoding , is the process of adding geographical identification metadata to various media such as websites, RSS feeds, or images. This data usually consists of latitude and longitude coordinates , though it can also include altitude and place names. </li></ul>Source:http://en.wikipedia.org/wiki/GeoTagging
  9. 9. <ul><li>Geocoding also refers to the process of taking non-coordinate based geographical identifiers, such as a postal address, and converting them into geographic coordinates . </li></ul>Also Source: ibid
  10. 10. <ul><li>GeoTagging can help users find a wide variety of location-specific information. For instance, one can find images taken near a given location by entering a latitude and longtitude into a GeoTagging-enabled image search engine. GeoTagging-enabled information services can also potentially be used to find news, websites, or other resources. </li></ul>Why Geotag? Source: ibid
  11. 11. Where Geotag? <ul><li>geotagged </li></ul><ul><li>geo:lat= latitude e.g. geo:lat=51.4989 </li></ul><ul><li>geo:lon= longitude e.g. geo:lon=-0.1786 </li></ul>
  12. 12. <ul><li>where latitude and longitude are the geographic coordinates of a particular location. These are expressed in decimal degrees in the WGS84 coordinate system, which has become something of a default coordinate system with the advent of GPS . </li></ul>At Taiwan, we can use TWD 97
  13. 13. How to Geotag? <ul><li>Just type it by using Google Earth , Google Map , PaPaGo or Urmap . </li></ul><ul><li>Or use real map. </li></ul>
  14. 14. Do it Directly! <ul><li>.CK’s GMiF </li></ul><ul><li>Dan’s Geobloggers </li></ul><ul><li>Steeev’s Greasemonkey scripts </li></ul><ul><li>UrMap Plus (Please docheck Geotagging Flickr in UrMap ) </li></ul><ul><li>Geotagging with Google Earth </li></ul>Definitely, you need to use Firefox + Greasemonkey!
  15. 15. <ul><li>Geobloggers GMiF - Google Maps in Flickr Steeev's Geotagging scripts GeoTagging Flickr Forum Firefox Greasemonkey Google Maps Google Earth 製作一個屬於自己的旅遊地圖 (use geobloggers ) </li></ul>Check them later!
  16. 16. What we need to do today? <ul><li>Upload our fieldwork photos </li></ul><ul><li>Use GMiF to geotag our fieldwork photos. </li></ul><ul><li>Try to use more than one solution beside GMiF. </li></ul><ul><li>Compare different solutions of geotagging </li></ul><ul><li>Figure out the framework of your project. </li></ul>
