NAME

WebService::PublicViewpoints - The Perl API to access the public-viewpoints geo-webservice.

SYNOPSIS

  use WebService::PublicViewpoints;

  my @points = WebService::PublicViewpoints->find(num => 10, country => "JP");

  for (@points) {
      say $->lat, $_->lng, $_->url;
  }

DESCRIPTION

WebService::PublicViewpoints is a Perl API to access the public-viewpoints geo-webservice available at http://public-viewpoints.appspot.com. Each viewpoint is basically a camera shoting at something.

To use it, invoke its `find` class method with constraints:

    my @points = WebService::PublicViewpoints->find(num => 10, country => "JP");

The possibile constraint key-values are:

• num: At least 1, the maximum number of results.

• random: "true" or "false".

• latitude, longitude: The viewpoints around this location are wanted.

• country_code: UK, US, JP, DE, FR.. etc.

• city: The city name, like "Miami".

The find method returns a list of point objects, so you catch them in an array. Each point object has these attributes:

• url: The URL of camera image.

• country_code: UK, US, JP, DE, FR.. etc.

• country: The name of the associated country_code.

• state: The state abbrevation for US.

• city: The city name.

• lat: The latitude of this camera image.

• lng: The longitude of this camera image.

The detail of the feasible contry/city values are unknown due to the lack of documentation of the origianl application site.

This work is a based on the work of public-viewpoints service at http://public-viewpoints.appspot.com
