Is there a way to retrieve latitude and longitude details of IRC channel so that I can locate the same on Map.
Thanks.
To get the locations of the people in the channel, you could simply look at their hostname - names on IRC are made up of a nickname, a username, and a hostname in the format nickname!username@hostname.
The hostname could be one of three things - an IP address, a DNS name, or a "cloak". You could use a DNS client to convert the hostname into an IP address, and then with the IP addresses you could use an IP geolocation tool (such as ipinfodb.com which has a nice free API), and retrieve the latitude and longtitude of each user.
If the hostname is a cloak, and the format of this varies between networks, then there's no way (unless you have advanced privileges on the IRC network) to get the real IP/hostname (and hence location) of that user.
