WARNING: experimental !

Mapnik's PluginArchitecture supports the use of different input formats.

This plugin supports reading WLANs found by running the kismet daemon.

Installation

There needs to be a running kismet_server process with activated GPS support before starting mapnik.

Parameters

parameter value description default
host string host where the kismet daemon is running
port integer port of the kismet daemon
extent string max extent of the kismet returned wlans
encoding string internal file encoding utf-8

Example

See next an example XML file to render WLAN icons on the map.
