[mapserver-users] Re: How to get full extent of the map?

[Rahkonen Jukka]

Hi,

Sorry, I do not make code, but you should make your application to send the getCapabilities request like
http://localhost/cgi-bin/mapserv.exe?service=WMS&version=1.1.0&request=getCapabilities&map=c:\ms4w\osm-mapserver.map

and capture the extents from the returned document which will have this kind of sections for each layer

   <Layer queryable="0" opaque="0" cascaded="0">
        <Name>landuse_layer5</Name>
<!-- WARNING: Mandatory metadata '..._title' was missing in this context. -->
        <Title>landuse_layer5</Title>
        <SRS>EPSG:3067</SRS>
        <LatLonBoundingBox minx="-7.18554e+205" miny="-90" maxx="7.18554e+205" maxy="90" />
        <BoundingBox SRS="EPSG:3067"
                    minx="-3.40282e+038" miny="-3.40282e+038" maxx="3.40282e+038" maxy="3.40282e+038" />
        <ScaleHint min="0" max="2494.51923117667" />
      </Layer>

Please notice that the both bounding boxes in this example are nonsense and I should obviously check my mapfile for correcting them.
