I am trying to set the symbol radius to 100 miles. This seems ok (note, not including the whole mapfile, just what's at hand here):
LAYER NAME POIs TOLERANCE 50 TOLERANCEUNITS miles LABELITEM "name" SIZEUNITS miles CLASS STYLE SYMBOL 'Airport' COLOR 61 245 0 SIZE 100 MINWIDTH 100 MAXWIDTH 100 END LABEL SIZE 9 END END
I'd like to keep the label size at 9. If I am NOT using
the label at size 9 looks fine. But using
SIZEUNITS miles makes it much much smaller.
After reading here: http://lists.osgeo.org/pipermail/mapserver-users/2012-February/071582.html it seems you can set a maxwidth and minwidth within your
STYLE to accompany for having the symbol width in pixels but the radius in miles (correct me if I am wrong).
When I zoom in on a handful of points, certain points and labels start to disappear. I know I could set
FORCE ON and
PARTIALS TRUE but this doesn't look good.
So what I would like to understand:
1) why are the labels becoming much smaller with
SIZEUNITS miles on?
2) why are certain points disappearing when zooming in (and some only showing up when zooming in, not initially present) when there seems to be ample room on the map for them to display without
FORCE ON? . Right click image link into new tab to see better view.
