G'Day all,
Is there a simple means of getting mapserver to zoom to the extent of a =
specific layer (or even all layers). I only ask because I noticed that =
when producing the GetCapatibilites XML document (I am using MapServer =
as a WMS Server) I noticed that it output the following tags for each =
layer, as well as the overall extent of all layers. Tags look like =
this:
<LatLonBoundingBox minx=3D"72" miny=3D"-55.9612" =
maxx=3D"170.731" maxy=3D"-2.10025" />
<BoundingBox SRS=3D"EPSG:4326" minx=3D"72" miny=3D"-55.9612" =
maxx=3D"170.731" maxy=3D"-2.10025" />
I am basically trying to implement an ESRI style "Zoom to Layer" type =
button and I don't want to hardcode the layer extents if I can get away =
with it. =20
Server=3D WIN XP running IIS with Mapplet and JavaScript
Cheers
Thomas Bartlett
