H3

The H3 (Hexagonal Hierarchical Spatial Index) display method will be useful in the analysis and comparison of any spatial data due to the uniform format of the location of cells.

The H3 in many ways is similar to the Hexbin. The difference is that H3 is a system with a fixed grid arrangement that does not depend on data.

H3 overview

To choose a display method:

  1. Go to the Layers tab.
  2. Select the layer group.
  3. Select the necessary layer.
  4. Select the H3 display method on the General settings tab.
  5. Set the remaining filter parameters if necessary.

The data will be visualized on the map.

For the H3 display method, the following parameters are available:

  • Resolution: the smaller this value, the larger the area covered by one element.

  • Coverage: coverage of the territory as a percentage from 1 to 100. Only the distance between the elements changes. The recommended value is 98-99.

  • Color: the color scale of the data display.

    • Color basis: the parameter based on which the elements on the map will be colored according to the Color scale. The available values depend on the selected data category.
    • Color scale: the set of prepared color samples.
    • Invert: select to invert the selected color scale.
    • Steps: gradation of the color scale from 1 to 10.
    • Legend: symbols for color and prepared data.
    • Color aggregation type: the color aggregation method — Sum or Mean.
    • Type of scale: Linear — displays of values of the same order; Logarithmic — displays of a wide range of values, when the values may differ by several orders of magnitude.
    • Opacity: setting the opacity of the elements on the map.
  • Height: enable to display the data as a bar chart. To enable three-dimensional display format, select the 3D in the bottom-right corner of the map.

    • Height basis: the parameter based on which the elements on the map will be formed. The available values depend on the selected data category.
    • Height aggregation type: the height aggregation method — Sum or Mean.
    • Height scale: column height multiplier from 0.1 to 20.
