Bug: Scalebar value is zero for an ArcMap Service

Description

The value of the scalebar acetate layer is zero for an ArcMap Service

Cause

There two known issues that may cause this:

1. **This issue has been resolved in ArcIMS version 4.0.1**

The scalebar value will be zero when the original map is in projected coordinates and the FILTERCOORDSYS in the GET_IMAGE request is in Geographic coordinates.

2.

** This issue has been resolved in ArcGIS 9.0. **



The spatial extent of the map is such that the scalebar is a fraction of the map's unit of measure. For example, if the map's unit of measure is in kilometers and the spatial extent of the map is less than a mile, the scalebar value is zero instead of a fraction of a kilometer.

Workaround

  1. If you are using ArcIMS 4.0, use the same projection to specify FILTERCOORDSYS in the GET_IMAGE request as in the Service.

  2. Scalebars for ArcMap Services (versions 4.0 and 4.0.1) do not support fractional units. To have a usable scalebar use smaller units. For example, use meters instead of kilometers.
