Consistant Scale Bar
October 20 2010 |
My scale bar needs to remain consistent at 1" = 25 miles. I don't want it too change when the end user zooms in or out. I understand that the length of the scale bar would change accordingly, but it needs to remain at 1" = 25 miles for example.
The end user needs to be able to get rough dimensions by scaling off of a hard copy out in the field. It is very difficult to do this if the scale bar is showing 1" = 12.67 miles.
Any help would be greatly appreciated. If I need to clarify my question, please don't hesitate to ask.
Mapping Center Answer:
To create a scale bar with a fixed division value, modify the scale bar properties so that the width of the scale bar changes with the map scale, instead of the other way around.
On the ‘Scale and Units’ tab under scale bar properties, select the “Adjust width” option under ‘When resizing. . .’ You can then manually enter the desired value in the ‘Division value’ field. One thing to keep in mind is that when working on a set of maps that span multiple scales; you’ll want to use a division value that is appropriate for each range of scales: small, medium and large.
