description = [[
This script queries the Nmap registry for the GPS coordinates of targets stored
by previous geolocation scripts and renders a Bing Map of markers representing
the targets.

The Bing Maps REST API has a limit of 100 markers, so if more coordinates are
found, only the top 100 markers by number of IPs will be shown.

Additional information for the Bing Maps REST Services API can be found at:
- https://msdn.microsoft.com/en-us/library/ff701724.aspx

--
-- @output
-- | ip-geolocation-map-bing:
-- |_  The map has been saved at 'map.png'.
--
-- @args ip-geolocation-map-bing.api_key The required Bing Maps API key for your
-- account. An API key can be generated at https://www.bingmapsportal.com/
--
-- @args ip-geolocation-map-bing.center GPS coordinates defining the center of the
-- image. If omitted, Bing Maps will choose a center that shows all the
-- markers.
--
-- @args ip-geolocation-map-bing.format The default value is 'jpeg', 'png', and
-- 'gif' are also allowed.
--
-- @args ip-geolocation-map-bing.language The default value is 'en', but other
-- two-letter language codes are accepted.
--
-- @args ip-geolocation-map-bing.layer The default value is 'Road',
-- 'Aerial', and 'AerialWithLabels' are also allowed.
--
-- @args ip-geolocation-map-bing.map_path The path at which the rendered
-- Bing Map will be saved to the local filesystem.
--
-- @args ip-geolocation-map-bing.marker_style This argument can apply styling
-- to the markers.
-- https://msdn.microsoft.com/en-us/library/ff701719.aspx
--
-- @args ip-geolocation-map-bing.size The default value is '640x640' pixels, but
-- can be changed so long as the width is between 80 and 2000 pixels and the
-- height is between 80 and 1500 pixels.
