Why do some panos fail?

[mhulse]

Can we stop the process if the image does fail?

Maybe regenerate another?

Good test:

$ npm run esv -- "9.74885,-63.15585550000003" --zoom max > ./foo.png

$ npm run esv -- "CAoSLEFGMVFpcE9ZUE5CQ3phaTFfeTd6dDFpR3RuTlJpY3lPV3VrSnEwdS0yRl9J" --id --zoom max > ./foo.png

Get panorama id from here: https://istreetview.com/CAoSLEFGMVFpcE9ZUE5CQ3phaTFfeTd6dDFpR3RuTlJpY3lPV3VrSnEwdS0yRl9J

Pano exists.

Thinking I need to just dissect the extract streetview module and get the code I need.

[mhulse]

Use this code:

https://github.com/mattdesl/google-panorama-equirectangular/tree/master/lib

And use browserify to pass pano.tiles to the above code; get images.

Next, create equirectangular.

After researching this some more, it looks like custom panos are hard to predict in terms of URL as they contain some sort of USER id.

I think the best option will be to figure out how to exclude custom panos from my primary Google maps script.

Here's an alternative/simpler way of getting rand lat/lon:

<script src="https://maps.googleapis.com/maps/api/js?v=3&key=xxxxxx"></script>
<script>
function TryRandomLocation(callback) {
  //var lat = (Math.random() * 90) - 90;
  var lat = Math.random() * Math.max((180 - 0 * .25), 120) - (90 - Math.min(0 * .25, 45));
  var lng = Math.random() * 360 - 180;
  var sv = new google.maps.StreetViewService();

  // Try to find a panorama within 50 metres 
  sv.getPanorama({
      location: new google.maps.LatLng(lat, lng),
      radius: 50
  }, callback);
}

function HandleCallback(data, status) {
    if (status == 'OK') {
      // Call your code to display the panorama here.
      console.log(data)
    } else {
		console.log('Trying again')
      // Nothing here! Let's try another location.
      TryRandomLocation(HandleCallback);
    }
}

window.onload = function() {
  TryRandomLocation(HandleCallback);
}
</script>

Might need to rethink my approach.

Some have suggested working with bounds of a country as the earth has a lot of ocean.

Going to just throw in check for copyright; if it's copyright Google, I'm going to assume streetview will work with the extensions I'm using.

[mhulse]

Just added in a conditional that checks the copyright. Works well enough for now.
