A Survey on Event Detection Models from Geo Tagged Twitter Stream

GeoStreams are spatio temporal continuous data streams which has the spatial information. Spatial information in simple terms is the location details of any surface on the earth. These location details are basically specified by its latitude and longitude values and also have more attributes than location specific information which may be a non-spatial data attribute too. Spatio-temporal documents which arrives continuously as data streams offers basic required information about the various local events. This Paper provides an overview of the various models to detect the events and to discover the trending topics using the geo tagged tweet streams with their implementation, comparison of various parameters and the challenges in the existing models.
