Definition

Geospatial localization is the estimation of global geographic location using, in part, geospatial analysis. Geospatial analysis uses statistical and other analytic techniques for data that has a geographic or spatial context to it, typically available in geographic information systems (GIS). Geographic location is typically ascertained using Global Navigation Satellite Systems (GNSS) like GPS and GLONASS, which requires simultaneous line-of-sight connection with multiple satellites to estimate location within an error margin of a few meters. These constraints limit the use of GNSS-based localization to outdoors with few obstructing structures in close proximity and a tolerance to uncertainty in exact location. In addition to these constraints, in many environments such as indoors, urban canyons,...
