Name Get Devices By A Spatial Query Chapter MiWi
Goal Enables spatial circular queries by providing a latitude, a longitude and a radius parameters.
Description Searches the data base for all devices that match the given spatial query parameters. If max results is being set with the query, only returns up to the limit number of devices matching the search criteria. The work done for the one query type also simplifies creation of more query types such as bounding box or complex shapes. The query supports latitude and longitude float point coordinates.
Rationale Important feature for virtual environments which are representation of real world places and potentially have geographic correspondance. This is useful for searching GPS enabled devices.
