Setting extraction queries for product classes

Extraction queries allow you to determine which features are going to be included on your products. The queries that are created at the product class level of your product library control what is extracted for the products, instances, and areas of interest within the product class. They can be defined for all or specific feature classes based on the specifications for your product class.

The most common method for configuring the extraction queries is to choose a table or feature class in the Tables drop-down list and create a WHERE clause that can be applied to records in the table or feature attributes in the feature class.

Extraction queries are a set of defined filters used to limit the creation of cartographic features. Cartographic features will not be created or maintained for features not meeting these queries. Extraction queries are ignored if the Use Geographic Extent is set to False on the class properties.

There are additional built-in filters that you can apply to a product class. You can also choose which series, product, or instance types are going to have features extracted, as described below:

• Series Type—The series type you want to use for extraction, if multiple types have been specified. By default, you can use all series types.
• Product Type—The product type you want to use for extraction, if multiple types have been specified. By default, you can use all product types.
• Instance Type—The instance type you want to use for extraction, if multiple types have been specified. By default, you can use all instance types.
• AOI Type—The area of interest type you want to use for extraction, if multiple types have been specified. By default, you can use all AOI types.
