Around the World in 80 Timesteps: A Generative Approach to Global Visual Geolocation

Computer Vision and Pattern Recognition
Global visual geolocation consists in predicting where an image was captured anywhere on Earth. Since not all images can be localized with the same precision, this task inherently involves a degree of ambiguity.

Internet geolocation

ACM Computing Surveys, 2009
Internet geolocation technology aims to determine the physical (geographic) location of Internet users and devices. It is currently proposed or in use for a wide variety of purposes, including targeted marketing, restricting digital content sales to authorized jurisdictions, and security applications such as reducing credit card fraud.

Whois Based Geolocation: A Strategy to Geolocate Internet Hosts

2010 24th IEEE International Conference on Advanced Information Networking and Applications, 2010
There are several strategies in the literature to geolocate Internet hosts, however the accuracy of their estimates is a common issue. Furthermore, accurate Internet host location remains a challenge due to incomplete domain registers. In this paper, we propose a classification for geolocation strategies and present the Whois Based Geolocation (WBG ...
