Stack Overflow for Teams is a private, secure spot for you and your coworkers to find and share information. I am making a heatmap with Google API v3.

I'll give an example. Lets consider earthquake magnitudes. I assign weights to each point to specify their magnitude. However google considers the density of points when you zoom out. The more points are in a place, the redder it gets.

But once you zoom out and the two points get closer in the map, google maps considers the number of points instead of the weights and as a result, it appears read. I want it to be the average i. Is this possible? There is a somewhat decent workaround if you are like me and don't have the processing time or power to generate an overlay and you can't modify any existing libraries to your liking.

I used the google maps heatmap library and set maxIntensity and dissipating to false. Setting the maxIntensity to a value of your choosing will solve the problem of your heatmap-points getting colored in relation to eachother instead of to 0 or a set value. Setting dissipating to false will disable the automatic radius settings that happen when you change zoom levels.

Next I made an event for every time the zoom level changed and in that event I set the radius to a value that seemed to represent my data in the most accurate way for that zoom level. Now to get rid of the problem where datapoints on the map blend and get added together into a big red blob, I decided to make a seperate grid on my map for every zoom level I want to use.

I average all the values that are boxed inside the same grid point and make sure that the grid is large enough to keep heatmap points from overlapping, but small enough to not look like a bunch of circles.

I found that the grid should be about 0. The radius of the heatmap point is set by google in pixels. That conversion method will work pretty well if you aren't planning on mapping much more than a small country.We tweet useful stuff daily Follow VWO. One product by Google that is increasingly being used is its location service, Google Maps.

Google Map tracks and stores data on literally every step you take, if the location services or GPS is enabled on the device. The heatmap thus generated is referred to as Google Maps Heatmap. It is fairly simple to overlay your own Google Maps heatmap as there are many APIs and tools available on the internet that you can use to generate this type of heatmap. Here is how you can create a Google Maps heatmap of your location history data using a tool called Location History Visualizer [1] :.

Head to Google Takeout [2] to download your location history data. The Google Takeout page has a list of data that you can choose to export.

After clicking next, you will be taken to the second step. The time taken to create the export depends on the amount of data involved. Google Takeout sends an email to the corresponding Google account as soon as the export creation is completed. Once the export is created, click on the download button. A zipped file will be downloaded to your device. Visualizer will take time to create your Google Maps Heatmap based on the intensity of data points it has to plot — higher the intensity, the longer it takes compared to lower intensity data sets.

And without any technical to-and-fro, a heatmap of your entire location history will be on your screen, with all the data points on a map. The heatmap generated looks something like the heatmap below:. As can be seen, creating your very own Google Maps Heatmap is a simple task — all it takes is 3 simple steps. And, Location History Visualizer is only one of the many tools that you can use to create a heatmap layer on location data. Once you have your location heatmap ready, you can take screenshots, navigate through it like Google Maps, identify places you visit most, and so on.

Apart from all these, it is a very interesting take on how you can go down the memory lane and revisit memories that were otherwise lost to you. Google Maps heatmap is a visualization of your location history, i.The heat map layer on Google Maps refers to displaying colors such as red, yellow, and green in order to display the intensity of the number of pins at points on the map.

Google's heat map layer has a variety of options bold items are changeable on our service available including : dissipating - whether or not the intensity radius increases or decreases based on the zoom level.

EasyMapMaker does not allow this to be configured, so the intensity changes when zooming in and out gradient - the colors used for the heat map.

EasyMapMaker does not allow this to be changed, so the default colors: mainly red, yellow and green are used max intensity - allows the maximum intensity color concentration to be limited instead of based on the number of pins. EasyMapMaker uses the number of pins for the intensity. The default is 0. EasyMapMaker allows this value to be set anywhere from 5 to A higher value means the size of the heat layer will be larger for each pin. The default is for only the heat map to be shown without pins.

When the option is enabled a menu appears below the heat map button on a map with the following options:. Heat Map Options. View Heat Map click fire icon in upper right.

A good sample map with the heat map layer enabled is the 14, zip code map. It shows a lot of zip codes on the east coast of the USA. Heat Maps: View intensity of pins on a map.A heatmap is a visualization used to depict the intensity of data at geographical points.

When the Heatmap Layer is enabled, a colored overlay will appear on top of the map.

By default, areas of higher intensity will be colored red, and areas of lower intensity will appear green. The Heatmap Layer is part of the google. To add a Heatmap Layer, you must first create a new HeatmapLayer object, and provide it with some geographic data in the form of an array or an MVCArray[] object. The data may be either a LatLng object or a WeightedLocation object. After instantiating the HeatmapLayer object, add it to the map by calling the setMap method.

A heatmap can render either LatLng or WeightedLocation objects, or a combination of the two. Both objects represent a single data point on a map, but a WeightedLocation object allows you to additionally specify a weight for that data point. Applying a weight to a data point will cause the WeightedLocation to be rendered with a greater intensity than a simple LatLng object.

LatLng You can mix weightedLocation and LatLng objects in a single array. Using a WeightedLocation object in place of a LatLng can be useful when:. You can customize how your heatmap will be rendered with the following heatmap options.

The Opacity slider controls how transparent the heatmap colors are.

It only takes a minute to sign up. Basically I tried to set the heat weight by commuterAmt so that it is not just simply plot a heat at each coordinates that I declared. However, it does not work. For every point on the map, it just simply plot a heat without taking account into the commuterAmt. Attached image shows the heat plotted on each bus stop. Although each bus stop has different commuterAmt but the heat seems all the same.
