Google Map Js Api "streetviewpanorama" Display Black Screen For Some Address
Solution 1:
Analysis
I believe you are experiencing the issue because the lat,lng is far away from the roads where the street view imagery is available. When I execute geocoding request for '2 Simei Street 3, Singapore, Singapore 529889' I can see that Google returns coordinate 1.3406241,103.9494707. Let's have a look at this coordinate in the Geocoder tool:
https://google-developers.appspot.com/maps/documentation/utils/geocoder/#q%3D1.340624%252C103.949471
If you drag the pagman to check where the street view imagery is available you will see the following:
So, indeed the distance between an address and roads is too big. If I understand correctly the StreetViewPanorama
class uses a default value for radius to search nearest panorama and this radius is shorter than the distance from address to roads.
Solution
To solve this problem you can use the StreetViewService
class that allows to search panos using a request object where you can specify a radius.
https://developers.google.com/maps/documentation/javascript/reference#StreetViewService
You can start searching with radius 50m, if no panos available you can increase the radius and try again. If nothing is found in a radius 200m you can stop searching and report that no street view is available.
Have a look at the following example.
Proof of concept
functioninitialize() {
var geocoder = new google.maps.Geocoder();
var address = "2 Simei Street 3, Singapore, Singapore 529889";
geocoder.geocode({'address': address}, function (results, status) {
if (status == google.maps.GeocoderStatus.OK) {
var latitude = results[0].geometry.location.lat();
var longitude = results[0].geometry.location.lng();
console.log(latitude + " " + longitude);
var svService = new google.maps.StreetViewService();
var panoRequest = {
location: results[0].geometry.location,
preference: google.maps.StreetViewPreference.NEAREST,
radius: 50,
source: google.maps.StreetViewSource.OUTDOOR
};
var findPanorama = function(radius) {
panoRequest.radius = radius;
svService.getPanorama(panoRequest, function(panoData, status){
if (status === google.maps.StreetViewStatus.OK) {
var panorama = new google.maps.StreetViewPanorama(
document.getElementById('street-view'),
{
pano: panoData.location.pano,
});
} else {
//Handle other statuses hereif (radius > 200) {
alert("Street View is not available");
} else {
findPanorama(radius + 5);
}
}
});
};
findPanorama(50);
}
});
}
