Proceedings of the ACM multimedia 2012 workshop on Geotagging and its applications in multimedia

Geotagging is the process of adding geographical identification metadata to various media files such as photos, videos, websites, messages, and tweets. In recent years, the rise of widespread use of GPS sensors and the increasing availability of open geographical databases has motivated a large volume of work on geotagging. The increase in the use of geotagging and improvements in geo-location support systems open up a new dimension for the description, organization and manipulation of multimedia data. This new dimension radically expands the usefulness of multimedia data both for daily users of the internet and social networking sites as well as for experts in particular application scenarios. The goal of GeoMM 2012, the ACM Multimedia 2012 Workshop on Geotagging and its Applications in Multimedia, is to bring together cutting-edge research in geotagging as well as novel applications related to geotagging. The workshop aims to facilitate in-depth discussions, the sharing of existing tools, and ultimately the enhancement of research efforts in this area. Seven papers are presented in GeoMM'12 covering topics including, but not limited to, innovative models of geotagging and interesting phenomenon in geotagging. Many new applications related to geotagging are explored. Moreover, two invited keynote speakers provide overviews of the state of the art in this field: Adam Rae (Yahoo! Research) will present a talk on "State of the Geotag: Where Are We?" and Hui Cheng (SRI International Sarnoff) will present a talk on "Geo-Locating Photos and Videos over Urban and Natural Terrain". Finally, a panel discussion explores in depth the promising future in this field.
