You need to keep an array of the google.maps.Marker objects to hide (or remove or run other operations on them). In the global scope: var gmarkers = []; Then push the markers on that array as you create them: var marker = new google.maps.Marker({ position: new google.maps.LatLng(locations[i].latitude, locations[i].longitude), title: locations[i].title, icon: icon, map:map }); // … Read more

First you have to add the eventlistener google.maps.event.addListener(map, ‘click’, find_closest_marker); Then create a function that loops through the array of markers and uses the haversine formula to calculate the distance of each marker from the click. function rad(x) {return x*Math.PI/180;} function find_closest_marker( event ) { var lat = event.latLng.lat(); var lng = event.latLng.lng(); var R … Read more
As there is no yet solution offered by the Maps API and manually filling in coordinates is nobody’s business, here’s a gem of an alternative. Found this answer on the GIS website–absolute lifesaver (would’ve saved jurihandl a LOT of minutes drawing Calgary, above ;D): You can get polygon coordinates in json for using with googlemaps … Read more
First of all we will get source and destination points between which we have to draw route. Then we will pass these attribute to below function. public String makeURL (double sourcelat, double sourcelog, double destlat, double destlog ){ StringBuilder urlString = new StringBuilder(); urlString.append(“http://maps.googleapis.com/maps/api/directions/json”); urlString.append(“?origin=”);// from urlString.append(Double.toString(sourcelat)); urlString.append(“,”); urlString.append(Double.toString( sourcelog)); urlString.append(“&destination=”);// to urlString.append(Double.toString( destlat)); urlString.append(“,”); … Read more
