//For getting the camera angle, I'm considering something like the below code

//based on query from here: https://a.mapillary.com/#get-searchimclose

var images = new Object() //this will store the JSON from the query
var img_start = //this will be the best image for camera angle and proximity, where the camera will start
var radius = parcel.item.road_dist //this is currently stored in feet, but with reprojection should be meters and then fills the variable for the currently selected parcel
var lat
var long
//lat and long are filled by the latitude and longitude property from the Mapillary JSON
var calc_ca = function (lat1, long1, lat2, long2) {
this function will calculate the bearing/angle in degrees from the Mapillary image (lat1/long1) to the parcel centroid (lat2/long2)
}

//at this point run the query in the link above, searching for a limit of ten images which are returned as a JSON, set this equal to var images

//run the below for loop on the JSON

for i in images {
ca_1 = calc_ca(i.lat, i.long, parcel.item.latitude, parcel.item.longitude); //where parcel.item is the selected parcel, and this tells the angle from image to parcels
ca_2 = i.ca; //this is the camera angle that is already recorded by Mapillary for the image
i.ca_diff = Math.abs(ca_1 - ca_2); //this finds the absolute value in difference for the camera angle's view and the angle from that camera to the property
};

//now each object should have the .ca_diff property, so run a function to order them from smallest to largest, something like this but I think I didn't do this exactly right yet:

function sortByKey(array, key) {
return array.sort(function(a, b) {
    var x = a[key]; var y = b[key];
    return ((x < y) ? -1 : ((x > y) ? 1 : 0));
});
};

var images_ca = sortByKey(images, 'ca_diff');     //this then runs the sort function 

var img_start = images_ca[0]; //this stores the image key from the image with the camera angle that most closely matches the angle from image to property center

//then you can initialize the viewer with your client_id, and the image your just found is img_start variable

var mly = new Mapillary
.Viewer('mly',
                <client_id>
                 img_start, {cover: true, cache: false, direction: false})
