Аннотация:The work outlines the approach to creating location-based services, where information about geocoordinates is replaced with data on network proximity. This approach is based on the use of network
proximity to identify the location of mobile users. The user's location is "snapped" directly to wireless access points, without computing geographic coordinates. Accordingly, geo-tagged users are
emulated using information about available wireless network nodes. The work describes the
components of the system that provides geo-tagging services, schemes with various functional
characteristics are proposed. A method for organizing an efficient and scalable storage of location
data of mobile users in a relational database is proposed. A demonstration system was created that
provides a geo-tagging service available as an open-source project.
