Entity Vectorization

Entity vectorization, including vectorization of point, line and polygon entities, also provides specific editing functions for polylines and polygons respectively.

• Smoothing Distance: This parameter is valid when smoothing is enabled. Specifies the average distance between two adjacent points after smoothing.

• Simplified Distance: Specifies the maximum distance deviation from points to lines to keep. As the distance gets smaller, the more points are kept, and the fewer points are removed from the line.
