thanks Tim,<br><br>i tested using your link and could not reproduce the problem there, so i did a few further tests using the same map file in the various ka-map variants that come in the ka-map package.<br><br>i found that the problem exists in many of the interface options but not all.
<br><br>in particular the WMS and Overlay index files do not show this problem. in these cases, the units of the scale bar never change between any of the zoom levels (it remains in miles all the way from 1:5,000,000 to 1:5,000). it looks like the WMS version still uses the old mapserver scalebar, while the Overlay variant uses the javascript based scalebar.
<br><br>however in the following variants the problem does occur: KaExplorer (default), Kaqua, tootip, WFS, winman, winman2, query. In all these, the scale bar changes units as the user zooms further in, and the progression of units used is not intuitive...
e.g. the progression from miles to feet to inches to feet, or miles to inches to feet (not logical) vs. miles to feet to inches (logical to me).<br><br>i should clarify that the scale being displayed is never wrong... just that the unit progression is non-logical.
<br><br>i also tested this with metric units, but the progression from kilometers to meters to centimeters never seemed to behave unexpectedly (I took the ratio all the way to 1:5 to check).<br><br>do you know how to turn off the units switching? i would be perfectly happy to just utilize miles at all of my zoom levels.... heck i'd be happy to use metric personally, but folks around here want english...
<br><br>thanks for any advice,<br><br>sacha<br><br><br><br><br><div><span class="gmail_quote">On 12/15/06, <b class="gmail_sendername">Tim Schaub</b> <<a href="mailto:noreply@geocartic.com">noreply@geocartic.com</a>> wrote:

strange behavior<br></font><br></div><div><span class="e" id="q_10f87c1559f7e977_1">
<div></div><br>i'm testing ka-map in ms4w. i noticed a strange behavior in the
scalebar when it is set in "english" units.<br><br>i have a series of set
scales ranging from 1:5,000,000 to 1:5,000. <br><br>when zooming in, the
ka-map scalebar switches the units displayed from "miles" to "feet" when the
scale hits 1:50,000. The units of feet should suffice for all the other zoom
levels available ( down to 1:5,000). <br><br>however for some reason the
scalebar switches to units of "inches" at the scale of 1:24,000, then switches
back to "feet" when zooming-in further ....<br><br>unfortunately my app is not
web accessible at this point, but my set-up is pretty much stock ms4w 2.2 with
kamap 1.0.b1<br><br>any ideas what is going
on?<br><br>sacha<br><br><br></span></div></blockquote></div>
