H3
The H3 visualization method uses a Hexagonal Hierarchical Spatial Index grid. Data is aggregated into fixed cells which positions do not depend on the data values. This method is useful for analyzing any spatial data due to its uniform format of the location of cells.
The method supports a 3D format for displaying data on the map as columns.
Overview
To select a visualization method:
- Go to the Dashboards tab.
- Open the required dashboard.
- Open a scene using the arrows
and 
. If there is only one scene in the dashboard, it opens automatically when you open the dashboard. - To open the layer, click
icon and select the required layer. - In the General settings block, select the H3 visualization method.
- Set the remaining visualization parameters if necessary.
The data is visualized on the map.
Parameters
Tooltip setup
Parameter | Description |
|---|---|
| Tooltip setup | Enable the option to customize the list of attributes that are displayed in the tooltip when hovering over the H3 cell on the map. Select the required attributes, change their order, and select an attribute aggregation type if necessary: for more details, see the Configuring a tooltip section. If the option is disabled, the tooltip shows all attributes from the dataset. |
Resolution
Parameter | Description |
|---|---|
| Resolution | Level of detail for an H3 cell from 1 to 15. The lower this value, the larger the area covered by a single cell. |
| Coverage | Coverage of the territory in percent. The recommended value is 98-99. Affects the distance between cells. |
Caption
Parameter | Description |
|---|---|
| Caption | Enable the option to display cell captions. The caption displays the attribute value from the Color basis parameter. |
Color
Parameter | Description |
|---|---|
| Color basis | Numeric attribute that determines the fill color of the H3 cells on the map and in the legend according to the color palette. Available values depend on the data in the sample. |
| Color palette | Set of prepared color samples. |
| Invert | Enable the option to invert the color palette. |
| Steps | Number of colors in the palette from 1 to 10. |
| Legend | Configuring data ranges in the legend. Ranges are calculated automatically based on the 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). In all ranges except the last one, 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 | Function used to aggregate the attribute values located in the H3 cell:
|
| Type of scale | Distribution type used to calculate data ranges in the legend:
|
| Opacity | Fill opacity in percent. |
Height
Parameter | Description |
|---|---|
| Height | Enable the option to display the data as 3D columns on the map. To enable 3D display format, select the 3D mode in the bottom-right corner of the map.  |
| Height basis | Numeric attribute based on which the data is grouped into columns. Available values depend on the data in the sample. |
| Height aggregation type | Function used to aggregate the attribute values located in one column:
|
| Height scale | Column height multiplier from 0.1 to 20. |
