Filter

Filter limits data visibility on your map using logical expressions (e.g., supermarkets with specific names) or spatial expressions (e.g., points within a bounding box). The filter allows you to focus on relevant information without altering original data. It works with point, line and polygon layers and with tables containing number, string, datetime, and boolean data types.

How to use the filter

Single Expression Filtering

1

In the Layers panel, click your layer. Its settings panel opens on the right with the tabs Style, Filter and Metadata. Select the Filter tab. For a table, the panel has only the tabs Filter and Metadata and opens on Filter.

2

Click + Add Expression to add a new filter expression.

3

Choose Logical Expression or Spatial Expression to define your filter type. For a table, a Logical Expression is added directly.

Logical expression

4

In Select field, choose the attribute to filter by.

5

In Select operator, choose the operator. Available options vary by data type (number, string, datetime, and boolean).

Expressions for number	Expressions for string
Is	Is
Is not	Is not
Includes	Includes
Excludes	Excludes
Is blank	Is blank
Is not blank	Is not blank
Is at least	Starts with
Is less than	Ends with
Is at most	Contains the text
Is greater than	Does not contain the text
Is between	Is empty string
	Is not empty string

Expressions for datetime	Expressions for boolean
Is on	Is true
Is not on	Is false
Is before	Is blank
Is after	Is not blank
In the last
Not in the last
Is between
Is not between

Hint

For datetime fields, choose a date from the date picker (Select date). "Is between" uses two dates (From and To), and "In the last" takes a Number of days. For boolean fields, the operator already sets the condition, so no value is needed.

Hint

For the expressions "Includes" and "Excludes", multiple values can be selected.

6

Set your filter criteria in Select Value, Select values or Enter value, depending on the operator. As soon as the expression is complete, the map updates automatically and the layer shows a filter icon in the Layers panel.

Spatial expression

4

In Select intersection method, choose the spatial boundary.

Map extent

With Map Extent, the layer automatically crops to the current map extent. To change the filter, zoom in/out and click the refresh icon (Use current map extent).

Multiple Expressions Filtering

Combine multiple filters by repeating steps 2-6 for each expression. As soon as there are two or more expressions, Filter results appears above them. In Filter results, choose Match all filters (AND) or Match at least one filter (OR) to control how filters interact.

Delete Expressions and Filters

Remove single expressions: Click on the More Options menu next to the expression, then click Delete to remove the expression.

Remove whole filter: Click Clear Filter at the bottom of the Filter tab to remove all filters.

Save as new layer

Once the filter is applied, click Save as new layer at the bottom of the Filter tab to save the filtered result as a new dataset in your workspace. This allows you to work with the filtered data independently.
