Use clustering to display large set of data on Google Map

Sometimes you might need to display a large set of data on Google map, and if you pinpoint every data point using a marker the map would soon be flooded by markers overlapping each other.

For example, you might need to display a map showing all the properties available for rent/sell, or a map showing information on historic mine, oil and gas locations.

For such cases, it would be very difficult to see all the markers, distinguish from each other, unless you zoom into a very detail level of the map.

One solution for this is to use ‘Clustering’. Clustering is a way to group pinpoints on the map based on factors such as proximity or category. This makes the map leaner, cleaner, and easier navigate.

Here is an example of map with clustered data points

When you click on a “cluster”, it will automatically zoom in and display all the data points within that cluster. And every data point can associate with an info box to display further details about the marker.

iMapBuilder (for Windows) comes with a wide range of map templates including country maps, state maps or county maps. These maps are based on HTML5, which means they can be view online, or offline (with no Internet connection) on all sorts of devices from PC, Mac to Mobile.

By using iMapBuilder, you could do the following by simply point-and-click actions:

1. Pinpoint locations, e.g. pinpoint local airports, International airports, private airports etc.

2. Add labels / annotation with each location (showing on mouse over)

3. Draw routes by using straight lines or curves with different colors

Here is a video tutorial on Youtube showing how to create the air route map.

In case you need to show a more detail map showing all the cities, streets, mountains, you can consider use iMapBuilder Online which is a custom Google Map builder.

Highlight multiple regions on a country map

There are many occasions where you need to highlight multiple regions together. For example, multiple states of a country, or multiple countries on the world map might belong to a specific ‘group’.

world country map with groupingYou might want to show them with the same color, and display the same message when user click on this specific “group”.

That’s why iMapBuilder provides Group highlighting which allows you to group multiple regions on the map together, as a new group.   So all regions of this ‘group’ are highlighted together on mouse on.
