<p>Hi Sarah,</p>
<p>I have had problems with circle symbols with sizeunit meters in
the past. So I presented some of my alternative solutions i a
talk at FOSS4G last year. Here is a link to the presentation:
<a class="moz-txt-link-freetext" href="https://github.com/LarsSchy/Mapserver-Circles/blob/main/MapServer-Circles.pdf">https://github.com/LarsSchy/Mapserver-Circles/blob/main/MapServer-Circles.pdf</a></p>
<p>The video is here: <a class="moz-txt-link-freetext" href="https://www.youtube.com/watch?v=vlagaZLxekg">https://www.youtube.com/watch?v=vlagaZLxekg</a></p>
<p>Some example code can be found at:
<a class="moz-txt-link-freetext" href="https://github.com/LarsSchy/Mapserver-Circles">https://github.com/LarsSchy/Mapserver-Circles</a>.</p>
<p>I do agree that there exists some problem with circle symbols
with size unit meters, that I really can't explain<br>
</p>
<p>Have fun!</p>

<p class="MsoNormal"><span lang="EN-US">I configured a point
layer with "circle" symbol and sizeunits meters. The circles
should have the same size in real world units (meter) for
all zoom levels, for example 100 m.<o:p></o:p></span></p>
<p class="MsoNormal"><span lang="EN-US">This works for most zoom
levels, but when I zoom in closely the circles get smaller
(< 100 m).<o:p></o:p></span></p>

any maxsize or minsize for the layer.<o:p></o:p></span></p>
