How do I create a density or heat map of my locations?

You can create a density or heat map of your locations using heat mapping software.

Density grids are a powerful tool that you can leverage to visualize your data. For example, it can be useful for showing hot spots of crime, mapping the concentration of healthcare providers, and analyzing the pattern of clients around a store weighted by the cost of their purchases. This article shows you how to work with the Density/Heat Layer tool in Maptitude:

The steps below show how to create a density map of the concentration of hospitals, but you can use any point layer (such as customers or crime locations) as the basis for your map.

Creating a Density or Heat Map in Maptitude Desktop

  1. Download a free mapping software trial of Maptitude Desktop or use your existing Maptitude Desktop license.
  2. Download the free healthcare data layer here: https://www2.caliper.com/store/product/health-care-mapping-data/
  3. Use the Create a United States Map option from the Home Window to create a map of any U.S. county (e.g., Los Angeles CA, Cook IL, Harris TX).
  4. Click  on the Standard toolbar and add the Hospital layer (ccHospital.cdf) that you downloaded in step 1 to your map.
  5. Choose Tools>Analysis>Density/Heat Layer or click  on the Standard toolbar.
  6. Choose Hospital from the Layer drop-down list and choose Visible Features from the Set drop-down list.
    Note: You are going to create a heat map showing the density of all hospitals in the county.
    If you wanted, you could focus on a subset of the hospitals by using a selection set.
    For a video tutorial on selection sets, see: https://www.caliper.com/learning/media/working-with-maptitude-selection-sets-filters/.
  7. Enter a name for the density grid layer, such as “Hospital Density,” in the Layer Name edit box and click OK.

Creating a Density or Heat Map in Maptitude Online

  1. Request a free mapping software trial of Maptitude Online or use your existing Maptitude Online account.
  2. Click Create Map at the top of the page.
  3. You can copy and paste the data you would like to map directly into the table.
    Or, click Browse and select your Excel file and Sheet that you would like to map.
    Click Next.
  4. Use the drop downs to properly configure your Excel columns. Click Next.
  5. Select one of the Locate options to see your data as points on the map.
    Click Next.
  6. Select the Heat Map Theme and click Next.
  7. If you are mapping your data as points, you can optionally add one of the following analyses: buffers, weighted center, and areas of influence.
    For more information on the analyses options, please see:
    Tutorial video on the buffer analysis in Maptitude.
    Tutorial article on the weighted center analysis in Maptitude.
    Tutorial video on areas of influence in Maptitude.
  8. Enter a name for the map and click Finish.

Maptitude computes the density grid and adds it to the map. The density at any location can be visualized by the color of the shading – usually blue to red for low to high density.
