Arcs

spatialware_type: spatialware_arc

Features with this value are point features with the point specifying the centre of the elliptical arc. This is used by both the reader and the writer.

Note: Currently, only circular arcs are supported by SpatialWare. FME will assign the same value to both the primary and secondary radii when reading, and will use the average of these when writing arcs to SpatialWare.

Arc features have the following special attributes associated with them:

Attribute Name

Contents

spatialware_primary_radius

The primary radius of the arc.

spatialware_secondary_radius

The secondary radius of the arc.

spatialware_start_angle

The start angle of the arc measured in degrees counterclockwise up from the horizontal.

spatialware_sweep_angle

The sweep angle of the arc measured in degrees counterclockwise.

spatialware_rotation

The rotation of the primary axis of the arc. The rotation is measured in degrees counterclockwise up from the horizontal.

spatialware_centroid_x

The feature’s centroid X location.

spatialware_centroid_y

The feature’s centroid Y location.

spatialware_centroid_z

The feature’s centroid Z location.

spatialware_is_closed

YES if the feature is closed. NO if otherwise.
