Adding a heatmap layer

Heatmaps are commonly used in geospatial mapping to visually display the density of points or features across a geographical area. A heatmap is a graphical representation of the data where the values are represented as colours on a map, with hotter colours indicating higher values and cooler colours indicating lower values.

You can easily add and configure a heatmap layer to your project in Coreo using the Maps & Boundaries page.

Note: The option to produce heatmaps is only available if your project contains point or multipoint geometries.

• Select the ‘Maps and Boundaries’ under the ‘Build’ header in the sidebar.

When you first arrive in the page you’ll start in the custom layers tab.

• Select ‘Import custom layer’.
• From the dropdown select ‘Heatmap’.

• In the Map Layer Name box type a name for your Heatmap, e.g ‘Heatmap’.
• Select your Heatmap Data Source from the drop-down list. This will either be Coreo Records or Coreo Collections. Select ‘Coreo Records’.
• Choose which Form you want to create a heatmap layer from – you will be presented with a list of potential forms which contain geospatial data suitable for creating a heatmap.
• Select ‘Add map layer‘ to add the layer to your project map.

Viewing your heatmap in the Coreo app

To view your new heatmap in the Coreo app, visit the relevant project and select the Layer Switcher icon.

• Scroll to the bottom of the window until you see the Map Layers section. Toggle the required layer (in this case “Heatmap”) to be visible.

• Tap back onto the map to dismiss the Layer Switcher and your heatmap will now be visible on the map.
