Selection requirements for tool to work

A polygon layer

This tool lets you generate a grid-based heatmap showing how much of each block is covered by your selected feature. It’s perfect for highlighting patterns, identifying hotspots, or summarising spatial distribution at a glance. Choose your grid size and extent, and us do the heavy lifting! We'll return a grayscale raster where brighter areas indicate greater coverage.

For example, selecting a grid cell size of 100 metres creates 1-hectare blocks, allowing you to visualise what percentage of each hectare is covered by your feature.

  1. Select a polygon layer

  2. From the context menu at the top of the interface, click the create heatmap button

  3. Choose the extent of the heatmap. It will default to the extent of your input layer, but you can select another layer instead if you want your heatmap to cover a smaller or larger area.
