**Background:**

OpenCities Map automatically creates geometric properties for recognized features. These properties are read-only and are described as *Geometry_Perimeter*,* Geometry_Area*, and *Geometry_Length*.

Queried spatial features are also assigned geometric properties which are described as *Database_Perimeter*, *Database_Area* and *Database_Length. * These values are calculated by the database.

**Rounding - Labeling**

Geometric properties can be used labeling where they can be rounded using the XFM Evaluator Expression *XFM.Round. *For example, the following will round Geometry_Area to two decimal places: *[XFM.Round([Geometry_Area],2). *

XFM.Round can also be used to round off database geometric properties. * *

**Rounding - Analyze Result dialog**

The decimal places shown in the Analyze Result for *Geometry_Length* and G*eometry_Permimeter* is driven by the accuracy of the working units of the design file.

The display of the decimal places for *Geometery_Area*, *Database_Length*, *Database_Perimeter* and *Database_Area* are not affected by this setting.

**Rounding - Data Browser**

The decimal places shown in the Data Browser can not be changed. This is true for both *Geometry* and *Database* properties.
