Filtering vector data¶

Filter tab¶

Sometimes you may want to hide some features by using indicators.

For example, only show where HDI is less than X value. In such case, filtering feature in GeoHub might be useful for you to visualize only focused features.

Add new filter rule¶

To use filtering, firstly please move to FILTER tab, then click NEW RULE button.

Select a property¶

Then, select a property you wish to filter by certain values.

After selecting a property and an operator, you need to select a value for filtering.

The user interface can vary according to the data type of selected property.

Note

When you add more than one rules to the layer, the toggle button on the top of FILTER tab might be important. As default, All conditions must be true (AND filter) is selected. You might need to change to One condition must be true (OR filter) to achieve your desired result.
