General Information - Location Lookup (GLQ/GLR)
Overview
The Nlets Location Lookup service leverages the Intrado Emergency Data Broker (EDB) to provide real-time incident information about a geographic location. Information about a location comes from Intrado's repository based on IoT inputs from multiple sources, including telematics, security, connected buildings, healthcare & wearables, and personal safety devices.
The Nlets Location Lookup service uses two messages keys, GLQ and GLR, to access the Intrado EDB via an API that Intrado has exposed for law enforcement access. Nlets users may search a location by address or geographical coordinates (latitude/longitude). The service returns a URL which users may paste into a browser to see an Intrado web page with information for the queried location.
Query Requirements
- Each query must include an Incident ID which may be from 1-20 characters in length.
- Users may specify a location by its address or by its latitude and longitude.
- Nlets will reject queries containing both address and latitude/longitude.

Responses
The response to a valid query will be a URL containing a short web link with an access token. Pasting the complete URL into a browser will bring up an Intrado-generated web page containing all information Intrado currently knows about the location, if any. The token expires after 60 minutes, after which the user must send a new query through Nlets to generate a new token.
