Which features in the linked feature class will be annotated by the annotation classįor example, if you have an annotation feature class for cities, you could have annotation classes of varying text sizes and scale ranges for small, medium, and large cities-all managed within a single annotation feature class.How the annotation text strings will be defined based on attributes in the linked feature class.Default symbology applied when creating new annotationįor feature-linked annotation, the following properties are added:.Each annotation class contains properties that determine how a subset of annotation in the feature class displays.įor both standard annotation and feature-linked annotation, these properties are: Standard and feature-linked geodatabase annotation feature classes contain one or more annotation classes. Similarly, standalone feature-linked annotation feature classes should link to standalone feature classes in the same geodatabase.Īn annotation feature class can be linked to only one feature class, but a feature class can have any number of linked annotation feature classes. When the value in its name field is modified, the text stored in its linked annotation feature is automatically updated with the new name.Ī feature-linked annotation feature class inside a feature dataset should link to a feature class within the same dataset. In the same network, the name of a transmission main may change. When the hydrant is moved, its linked annotation moves with it. ![]() In the water network example, a hydrant may be too close to a busy intersection and may need to be moved 50 feet. When an origin feature is deleted from the geodatabase, the linked annotation feature is also deleted. When the origin feature is moved or rotated, the linked annotation also moves or rotates with it. If an attribute value for the origin feature changes, the linked annotation that is based on this attribute will automatically update to reflect the change. ![]() As with other composite relationships, the origin feature controls the destination feature. The feature class being annotated is the origin class in the relationship, and the annotation feature class is the destination class. For example, the water transmission mains in a water network can be annotated with their names, which are stored in a field in the transmission mains feature class.Īnnotation links to features through a composite relationship with messaging. The text in feature-linked annotation reflects the value of a field or fields from the feature to which it's linked. No specific feature represents the mountain range, but it is an area you want to mark.įeature-linked annotation is associated with a specific feature in another feature class in the geodatabase. An example of standard annotation is the text on a map for a mountain range. Standard annotation is not formally associated with features in the geodatabase. There are two kinds of annotation in the geodatabase-standard and feature-linked. Learn more about annotation groups versus geodatabase annotation Standard and feature-linked annotation Note:įeature-linked annotation feature classes can be created and edited in ArcGIS Desktop Advanced and ArcGIS Desktop Standard, but they are read-only in ArcGIS Desktop Basic. Geodatabase annotation is indexed spatially, meaning that it will draw and select much faster. Working with geodatabase annotation in ArcMap will generally be faster than working with map document annotation. ![]() If you have more than a few hundred pieces of text or if you want editable text that you will use in many maps, use geodatabase annotation. The two other main options for storing text in ArcGIS are dynamic labels and map document annotation. Annotation is typically text, but it can also include graphic shapes-for example, boxes or arrows-that require other types of symbology. Each text annotation feature has symbology including font, size, color, and any other text symbol property. As with other feature classes, all features in an annotation feature class have a geographic location and attributes and can either be inside a feature dataset or a standalone feature class. Annotation in the geodatabase is stored in annotation feature classes.
