I have two vector layers in my map file that are at very different resolutions, and overlap somewhat. This is causing me some issues, and I would be happy if the higher resolution layer simply ended at the beginning of the lower resolution layer.
Here's the layer I'd like to crop (I've removed a bunch of class definitions):
LAYER NAME "DEPCNT_CA276800" TYPE LINE DUMP true TEMPLATE fooOnlyForWMSGetFeatureInfo EXTENT -65.4994451 42.6667472 -65.243000 44.6667528 DATA "DEPCNT" METADATA 'ows_title' 'DEPCNT_CA276800' END #metadata" STATUS ON CONNECTIONTYPE OGR CONNECTION "./s57/CA276800.000" TRANSPARENCY 100 PROJECTION 'proj=longlat' 'datum=WGS84' 'no_defs' END #projection CLASSITEM 'VALDCO' CLASS EXPRESSION ( (0 < [VALDCO]) AND ([VALDCO] <= 10) ) NAME 'DEPCNT' STYLE WIDTH 0.91 COLOR 0 170 255 END #style LABEL TEXT "0" SIZE 10 ANGLE FOLLOW POSITION AUTO FORCE TRUE ANTIALIAS TRUE END #label END #class .... CLASS EXPRESSION ( (200 < [VALDCO]) AND ([VALDCO] <= 210) ) NAME 'DEPCNT' STYLE WIDTH 0.91 COLOR 0 170 255 END #style LABEL TEXT "200" SIZE 10 ANGLE FOLLOW POSITION AUTO FORCE TRUE ANTIALIAS TRUE END #label END #class
END #layer DEPCNT_CA276800
No matter what I set the maxx of EXTENT to it draws the entire X range of the layer. Is what I'm trying to do even possible, or is there some other method I could try?
