All,
Is there any way to get a dataset extents from MapServer CGI directly
(no Mapscript)?
Jan / Bob,
How would you see this working? Would it be a request made against a
particular layer? Against the map as a whole? Internally in the code we
have:
int msLayerGetExtent(layerObj *layer, rectObj *extent)
which calls the data source specific GetExtent function. But I don't think
this works for raster layers. There is also msOWSGetLayerExtent() which
first consults the layer metadata for extents. Perhaps this would be the
logical place to look?
Well, I suppose the other side of this is that for WMS and WCS the layer
and coverage descriptions include extents already. Is that sufficient for
your needs?
Best regards,
