This sample passes the markers array to the MarkerClusterer. You can view more complex examples of marker clustering in the repository on GitHub and read the reference documentation for the library.

If you decide to use custom icons to represent clusters on the map, the same tips outlined for custom marker images will apply. This tip might seem obvious, but it can be easy to forget and just as easily kill performance. Our map object gives us access to a getBounds method on the current instance that allows us to determine the visible portion of the map based on its position and zoom level.
Since we'll already have access to all of the markers we defined and saved to state, we can update our call that adds the markers to our clusterer object to only include those whose current position is within the map's current bounds.
Doing so will significantly reduce the amount of data added to the map on the first render. Let's switch gears and change our application's purpose to be one that displays a map of nearby homes for rent to your user based on their location. Assume that we've updated our code to retrieve the user's current location when our map component is mounted. We can post those coordinates to an endpoint in Laravel, using Axios, for example, that will only return homes within an x mile radius from the user.
To do this, let's add a nearLocation scope to our Home model that will take in a latitude and longitude. In the example below, we're restricting the homes returned to be within miles of the provided location. I encourage you to check it out if you haven't already. Note: For the best user experience, allow the user to pick the mile radius they'd like to restrict their results to and pass that into the request along with their location. While Marker Clustering provides a great solution for grouping markers in close proximity, there is no out of the box solution provided by the Google Maps API that handles interacting with markers with the same coordinates.
No matter how close you zoom in, you'll always see just one marker with the others hidden beneath it. Any events registered to the markers will only apply to the topmost marker in the stack. So how can you reveal the remaining markers? Disclaimer: At the time of writing this post, Overlapping Marker Spiderfier has not been actively contributed to, but is a great starting point should you decide to fork it and add additional features or try your hand at contributing to the original!
Overlapping Marker Spiderfier , or OMS, is a cool open-source package that will add enhanced listeners to your map allowing overlapping markers to spring apart when the topmost marker in the stack is clicked. Luckily for us, OMS plays very nicely with the clustering we have included, too. Let's add it to our example code to see it in action. First, we'll add a script tag to our main view file with the link to the package file's minified version.
View example. To remove a marker from the map, call the setMap method passing null as the argument. Note that the above method does not delete the marker. It removes the marker from the map. If instead you wish to delete the marker, you should remove it from the map, and then set the marker itself to null. If you wish to manage a set of markers, you should create an array to hold the markers.
Using this array, you can then call setMap on each marker in the array in turn when you need to remove the markers. You can delete the markers by removing them from the map and then setting the array's length to 0 , which removes all references to the markers. You can customize the visual appearance of markers by specifying an image file or vector-based icon to display instead of the default Google Maps pushpin icon.
You can add text with a marker label , and use complex icons to define clickable regions, and set the stack order of markers. In the most basic case, an icon can specify an image to use instead of the default Google Maps pushpin icon. To specify such an icon, set the marker's icon property to the URL of an image. You can use custom SVG vector paths to define the visual appearance of markers. To do this, pass a Symbol object literal with the desired path to the marker's icon property. You can define a custom path using SVG path notation , or use one of the predefined paths in google.
The anchor property is required in order for the marker to render correctly when the zoom level changes. Learn more about using Symbols to create vector-based icons for markers and polylines.
A marker label is a letter or number that appears inside a marker. The marker image in this section displays a marker label with the letter 'B' on it. You can specify a marker label as either a string or a MarkerLabel object that includes a string and other label properties. When creating a marker, you can specify a label property in the MarkerOptions object.
Alternatively, you can call setLabel on the Marker object to set the label on an existing marker. You can specify complex shapes to indicate regions that are clickable, and specify how the icons should appear relative to other overlays their "stack order".
Doing it automatically would be much better and thanks to the search field, you can easily place the pinpoint perfectly on the place which you wanted to mark. Adding multiple points on Google Maps through search field is pretty easy and you can use in two ways:. Of course, after you add the location marker to your layout you will notice edition options, where you can:.
Thanks to you can add a missing place on the map and the mark will be added to your interface. Pretty simple — back to Google Maps and open the map you have created before. Now you know how to add multiple map markers on Google Maps! But for some people, it might not be enough….
If you just wanted to create map markers thanks to which you can go sightseeing to the other country or city, you already have learned anything. If you are a developer or even just an owner of some online stores, restaurants, etc. Adding an HTML code of your map is pretty easy and even non-coders should be fine with it. At first, you have to generate it and then you can prepare yourself to paste it into your website code.
To show you how to install Google Maps as a script we will use our Shopify website. You just need to paste the HTML code to the header or footer, or wherever you want to have your Google Map with multiple pinpoints. To prove that it also works on other platforms we will also try to install a code on a WordPress website. If you are using a CMS software and you are not sure where you can paste the code, you probably should check our guide about how to add a store locator or Google Maps to Shopify but if you are using other CMS or other e-commerce platforms on your website.
On the Nearplace website, you will find tutorials for every popular platform. API Method is harder to use, but it seems to allow more control over the entire process. Here you can find the fast how to for API method:. If you have any knowledge about coding, and you would like to add everything through the code, using Google Maps API might be a great idea to show your multiple locations. First, you need to create an account on Google Maps Platform which requires a couple of things to choose.
The first choice you have to do is to check what are you planning to use on your map. Now you have to create your billing account because Google has decided recently that now if you want to create an account you have to type in your credit card info, so they can charge you when you use the free limit. You can read more about it in our other article. In the next steps, you need to choose your account type, and insert your personal data. Immediately after creating an account you will also notice a pop-up with your API key.
To show you how you can use Google API we will use a normal code editor, which might be used to build a website. You can notice many values in the code. Now once you want to add more than one marker just do everything like with a first marker.
Maybe it took much space but is the most simple method you could have ever imagined. From the technical view of adding multiple pinpoints to the Google Maps, it is all. If you are a fan of good animations you can always animate your own pinpoints through the API code.
Once again we advise you to visit a Google developer website because you can find there almost everything about the Google API modifications.
