Problems solved by technology

However, GPS may not accurately represent indoor locations because GPS may not identify locations within enclosures such as buildings
In this way, location-based services may be limited to tracking outdoor locations

Embodiment Construction

[0018] The claimed subject matter is now described with reference to the drawings, wherein like reference numerals are generally used to refer to like elements throughout. In the following description, for purposes of explanation, numerous specific details are set forth in order to provide an understanding of claimed subject matter. It may be evident, however, that claimed subject matter may be practiced without these specific details. In other instances, structures and devices are shown in block diagram form in order to facilitate descriptions of the claimed subject matter.

[0019] Many devices provide location-based services utilizing location-tracking functionality (such as GPS) within an enclosure (e.g., building, multi-storey building, shopping mall, tunnel, subway, etc. (e.g., where a GPS signal may not be available) , blocked, etc.)) can not provide relatively accurate location tracking. Thus, as provided herein, a location (eg, the location of an object such as a mo...

Abstract

Among other things, one or more techniques and / or systems are provided for locating a position within an enclosure. In one example, known global coordinates (e.g., GPS coordinates of latitude / longitude) associated with the position within the enclosure may be transformed into local coordinates (e.g., x / y coordinates) for the position. The local coordinates may be used for tracking a location of the position within the enclosure. In another example, known local coordinates of the position within the enclosure may be transformed into global coordinates for the position, which may be used for tracking a location of the position within the enclosure. In another example, a blueprint image of the enclosure may be used to track a location of the position within the enclosure. In this way, location tracking may be provided for objects within indoor spaces (e.g., a mapping application may track a current position of a mobile device within a building).

Description

Background technique [0001] Many devices provide location-based services that utilize location tracking. In one example, a mapping service on a mobile phone may utilize global coordinates (eg, location information from a Global Positioning System (GPS), such as longitude and latitude) to identify the current location of the mobile phone. In this manner, a user can plan a travel route from a current location to a particular destination of interest to the user. In another example, a restaurant application on a tablet device may utilize location information, such as global coordinates, to suggest local restaurants to the user. Current location tracking technologies utilize global coordinates associated with GPS, which can provide relatively accurate longitude and latitude information for outdoor spaces. However, GPS may not accurately represent an indoor location because GPS may not identify a location within an enclosure, such as a building. In this way, location-based servic...
