(r): Attribute or child element is required.

Description

The process of data densification adds points to a layer before the layer is projected. DENSIFY sets the interval used for adding points.

Notes

Using DENSIFY can slow down the ArcIMS Spatial Server noticeably. Use DENSIFY only when features are missing from one or more layers in a requested image, usually around the periphery. It is better to start with a large number for tolerance. A guideline is to start with a value about 20 to 30 percent of the distance between the minimum and maximum x-coordinates of the current map extent.
The units for tolerance are the same as the units for the layer. For example, if the layer is in feet, the tolerance distance is in feet.
DENSIFY is only needed if a layer is going to be projected. If the layer is in the same projection as the ArcIMS service, DENSIFY does not need to be used.
For more information on the projection elements, see Using Projection Elements.
