H3

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

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

Overview

To choose a visualization method:

1. Go to the Dashboards tab.
2. Open the required dashboard.
3. To open a scene, use the arrows and . If there is only one scene in the dashboard, it opens automatically when you open the dashboard.
4. To open the layer, click icon and select the required layer.
5. In General settings, select the H3 visualization method.
6. Set the remaining visualization parameters if necessary.

The data is visualized on the map.

Parameters

For the H3 visualization 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.

• Caption: turning on the caption on H3 elements.

• Color: selecting the color of the data display.

  • Color basis: attribute based on which the elements on the map and in the legend are colored according to the color scale. The available values ​​depend on the data in the sample. You can select only numeric attributes.

  • Color scale: set of prepared color samples.

  • Invert: select to invert the selected color scale.

  • Steps: number of steps in the color scale from 1 to 10.

  • Legend: configuring of data ranges in the legend. Ranges are calculated automatically depending on a type of scale (for Logarithmic, Linear, and Exponential types). You can also customize ranges manually by entering the required range limits or changing the order and number of ranges (Adjustable type). The specified upper (right) limit is not included in the range. The maximum number of ranges is 10.
    To change the order of ranges, hold down icon next to the required range and drag it. To add a range, click icon. To delete a range, click icon.

  • Color aggregation type: color aggregation method for one visualization element (a H3 cell): Sum or Mean. The aggregation type is displayed in the tooltip when hovering the cursor over a cell on the map.

  • Type of scale: distribution type used to calculate data ranges in the legend:

    • Logarithmic - displays a wide range of data. Recommended to use if values ​​differ by several orders of magnitude.
    • Linear - displays values ​​of the same order.
    • Exponential - displays data that changes quickly. Recommended to use if you need to highlight small values and ignore large values.
    • Adjustable - manual configuring of ranges. In all ranges except the last one, the specified upper (right) limit is not included in the range.

  • Opacity: setting an opacity of the elements on the map.

• Height: enable to display the data as a column chart. To enable three-dimensional display format on the map, select the 3D in the bottom-right corner of the map.

  
  • Height basis: parameter based on which the elements on the map are formed. The available values ​​depend on the data in the sample. You can select only numeric attributes.
  • Height aggregation type: height aggregation method (Sum or Mean).
  • Height scale: column height multiplier from 0.1 to 20.
