Layer Filters

This feature allows you to filter the features from a data source so that only those meeting specific criteria are included in the layer. This enables you to create multiple layers based on the same data source, each showing a distinct subset of features.

Filtering is done using conditions. Only features that satisfy the defined conditions will be displayed in the layer.

The Filters section, accessible by clicking the icon, allows you to configure the conditions applied to the layer.

1	Click + to add a condition.
2	Condition components: Attribute : Select the attribute from the drop-down list. All attributes of the DS are available. Operator : Select the operator from the drop-down list. Operators vary depending on the type of attribute selected (text, integer, double, date). The Filter operators section describes each of them. Value : Enter the attribute value that will be used to filter the elements.
3	You can add a condition, update it by changing its components, or delete it.

Filter operators

The operator filters DS elements to conserve in the layer the elements whose:

equals: attribute value (regardless of its type) is equal to one of the specified values.

does not equal: attribute value (regardless of its type) is different from the selected values.

greater than: attribute value (numeric or date) is greater than the selected value.

greater or equal to: attribute value (numeric or date) is greater than or equal to the selected value.

less than: attribute value (numeric or date) is less than the selected value.

less or equal to: attribute value (numeric or date) is less than or equal to the selected value.

contains: attribute value (text) contains the selected value.

does not contain: attribute value (text) does not contain the selected value. This is the same as making a query with the WHERE clause attribute_name NOT LIKE '%value%'.

is null: attribute value (regardless of its type) is null.

is not null: attribute value (regardless of its type) is not null.

is between: attribute value (numeric or date) is within the range defined by the two entered values.

is not between: attribute value (numeric or date) is not within the range defined by the two entered values.
