Hi Ben

maybe something like this :

    CLASS 
        EXPRESSION ([the_name_of_the_elevation_field_of_your_layer_source] >= 50 and [the_name_of_the_elevation_field_of_your_layer_source] <55 and [the_name_of_the_size_field_of_your_layer_source] = 1000)        
        SIZE 50
        NAME "blabla:50-55"
        COLOR 255 255 102
    END

see http://mapserver.gis.umn.edu/docs/reference/mapfile/class and http://mapserver.gis.umn.edu/docs/howto/msexpressions for more details about expressions

regards
Oliver

  Hello Oliver, 
  <!--[if !supportLineBreakNewLine]-->
  <!--[endif]--> 

  I would like to have a point displayed on my map. I would like the point size to represent the population of a settlement, and I would like the point color to represent the elevation of the settlement. How can I structure my map file (layer classes) to do this?

  Thanks, Ben
