PointCloudValueFilter

A filter to include or exclude points using attribute values. This filter includes or excludes points in a PointCloudLayer based on an attribute value. For example, LiDAR point classifications that specify the type of surface reflected by the laser pulse are typically stored in the "CLASS_CODE" attribute. The different categories (for example building, high vegetation, ground) are defined using numeric codes in the LAS files. The PointCloudValueFilter can be used to include or exclude points based on these classification codes by specifying the "CLASS_CODE" attribute as the attribute name and the corresponding numeric integer codes as the values for the filter. The full list of categories, including the corresponding codes, can be found in the LAS specification.
