How to know if street view panorama is indoors or outdoors

问题

Today more and more businesses use street view to show apartments from indoors.

My program supplies ability to show street view according to selected business. But I don't want to show indoors. Only Outdoors. Because Indoors blocks me to move, only to turn 360 degrees.

Does anyone know how to fetch from street view API some value if I'm going to show indoors or outdoors?

Thank you very much,

This is my snippets of code so far that open street view according to selected address:

function load_map_and_street_view_from_address(address) {

var geocoder = new google.maps.Geocoder();
geocoder.geocode( {
    'address': address
}, function(results, status) {
    if (status == google.maps.GeocoderStatus.OK) {
        var gps = results[0].geometry.location;
        create_map_and_streetview(gps.lat(), gps.lng(), 'map_canvas', 'pano');
    }
 });
}


function create_map_and_streetview(lat, lng, map_id, street_view_id) {
var googlePos = new google.maps.LatLng(lat,lng);

addLatLng = new google.maps.LatLng(lat,lng);
var service = new google.maps.StreetViewService();
service.getPanoramaByLocation(addLatLng, 50, showPanoData);

}

function showPanoData(panoData, status) {
if (status != google.maps.StreetViewStatus.OK) {
    $('#pano').html('No StreetView Picture Available').attr('style', 'text-align:center;font-weight:bold').show();
    return;
}
$('#pano').show();
var angle = computeAngle(addLatLng, panoData.location.latLng);

var panoOptions = {
    position: addLatLng,
    addressControl: false,
    linksControl: false,
    panControl: false,
    zoomControlOptions: {
        style: google.maps.ZoomControlStyle.SMALL
    },
    pov: {
        heading: angle,
        pitch: 10,
        zoom: 1
    },
    enableCloseButton: true,
    visible:true
};

panorama.setOptions(panoOptions);

}

function computeAngle(endLatLng, startLatLng) {
var DEGREE_PER_RADIAN = 57.2957795;
var RADIAN_PER_DEGREE = 0.017453;

var dlat = endLatLng.lat() - startLatLng.lat();
var dlng = endLatLng.lng() - startLatLng.lng();

var yaw = Math.atan2(dlng * Math.cos(endLatLng.lat() * RADIAN_PER_DEGREE), dlat)
* DEGREE_PER_RADIAN;
return wrapAngle(yaw);
}

function wrapAngle(angle) {
if (angle >= 360) {
    angle -= 360;
} else if (angle < 0) {
    angle += 360;
}
return angle;
};

The main Idea was to get Panorama location and verify distance to closest places around 360 degrees.

I can't seem to find any formal API for this (maybe in the future they will implement one), and I don't think that you can be sure that indoor tiles will be with empty description.

What I found to be working for me is using this API: Run an HTTP GET to this address: "http://cbk0.google.com/cbk?output=xml&ll=52.358445,4.88103" with the ll=LONG,LAT

This is an internal API used to find a target location pano_id. It also gives us some information on what we can do with it: zoom levels, what streets you're on, etc.

I've noticed that all the results for coordinates that have indoor street view images, have scene="_number" level_id="_id" in the data_properties tag of the panorama. And so, for each location you can run this request and look for these values in the data_properties of the result XML

some examples:

indoors:
http://cbk0.google.com/cbk?output=xml&ll=52.358445,4.88103
http://maps.google.com/cbk?output=xml&ll=32.051626,34.7613

outdoors:
http://cbk0.google.com/cbk?output=xml&ll=52.358766,4.880494
http://maps.google.com/cbk?output=xml&ll=32.07782,34.785789

Update

It seems that to get local businesses right pano_id you need to add &it=all to the request example:

http://cbk0.google.com/cbk?output=xml&hl=x-local&ll=34.058593,-118.240673&it=all

this the the right pano_id for this place, you can verify it using this API

http://cbk0.google.com/cbk?output=tile&panoid=70o9Pukc2KSjO-PfeHussw&zoom=3&x=5&y=1

Here's a feature request I filed with Google:
"Option to disable indoor street views"
https://code.google.com/p/gmaps-api-issues/issues/detail?id=4831

Feel free to star the ticket there to help it get some attention

(Is this OK etiquette-wise? ...not a real answer (yet), but seems worthy of sharing here so interested parties can star/track the ticket)

The ability to filter out indoor street view panoramas was implemented in Google Maps JavaScript API some time ago.

You can use StreetViewService to search only outdoor panoramas. In the request you should specify the source as outdoor

https://developers.google.com/maps/documentation/javascript/reference/3/#StreetViewSource

Have a look at the following sample code that demonstrates how to get only outdoor panoramas

var panorama;
function initialize() {
    var svService = new google.maps.StreetViewService();
    var panoRequest = {
        location: new google.maps.LatLng(37.800953,-122.436738),
        preference: google.maps.StreetViewPreference.NEAREST,
        radius: 50,
        source: google.maps.StreetViewSource.OUTDOOR
    };

    svService.getPanorama(panoRequest, function(panoData, status){
        if (status === google.maps.StreetViewStatus.OK) {
            panorama = new google.maps.StreetViewPanorama(
                document.getElementById('street-view'),
                {
                    pano: panoData.location.pano,
                    pov: {
                        heading: 10,
                        pitch: 10
                    }
                });
        } else {
            //Handle other statuses here
        }
    });
}

html, body {
  height: 100%;
  margin: 0;
  padding: 0;
}
#street-view {
  height: 100%;
}

<div id="street-view"></div>
<script async defer
         src="https://maps.googleapis.com/maps/api/js?key=AIzaSyDztlrk_3CnzGHo7CFvLFqE_2bUKEq1JEU&callback=initialize">
    </script>

I hope this helps!
