All,
<div class=""><br class="">
</div>
<div class="">I’m working on a Parcel Assessment app that will display Parcel edges and which streets they abut. I’m trying to label each edge of the parcel with it’s Edge length, but the positioning of the labels is not at all what I’m expecting in the output.
Here is a sample image:</div>
<div class=""><br class="">
</div>
<div class=""><a href="https://www.dropbox.com/s/ppp1cihnl4flycf/rc_parcels_assessment.02.png?dl=0" class="">https://www.dropbox.com/s/ppp1cihnl4flycf/rc_parcels_assessment.02.png?dl=0</a></div>
<div class=""><br class="">
</div>
<div class="">The blue lines represent a connection from the center of each of the parcel edge segments being assigned, to the approriate Street/Alley centerline (not shown). I can’t seem to get the labels to center them selves on the segments. There should
be one distance label centered on each segment at the start of each of the blue lines where they intersect the red parcel edges.</div>
<div class=""><br class="">
</div>
<div class="">My next workaround would be to use a centroid of the line as the label point. I think I’ve tried all available combinations of settings in the Mapfile, but maybe I missed something. </div>
<div class=""><br class="">
</div>
<div class="">Anyone have any ideas?</div>
