feet since it was created off a US Foot coordinate system or is it assuming
Meters on coordinates sent in???) We Use Measure and dist to create the buffer
so since a one unit coordinate change returns 3.27654107864 it makes sense why
the distance would come up so much smaller. $geomBuffer =
$geom->Buffer($dist, $measure); <o:p></o:p></span></p>

<p class=MsoNormal>Hello I am using Mapguide Open Source as my Server and
Autodesk Mapguide Studio as my Authoring tool.<o:p></o:p></p>
<p class=MsoNormal>All my Maps are Using state Plane feet in Different
States…When I run a 66 foot buffer, it comes out 1/3 of what it should be, when
I run a 66 Meter buffer they run in what looks like feet…<o:p></o:p></p>
<p class=MsoNormal>Is this an issue with Mapguide Open Source trying to Buffer
a map Made in Mapguide Studio and not recognizing Autodesk Coord Systems in the
open Source Server?????? If so how do we address this for people that want to
buy Studio but Use Open Source for their Server????? Or is this part of a
bigger more Nefarious Issue?<o:p></o:p></p>
