[mapguide-users] GetFeaturesKml and GetLayerKml

[Jason Birch]

Hi,

Absolutely you can, it's just that the original RFC intended these as
interactive APIs created from the initial GetMapKML rather than
individual layer/feature access APIs.  I don't think there's any problem
with it, but haven't seen a lot of experimentation either...

That would be the approach that I'd take as well if I was going to try
using the build-in functions; DMSG wrote something similar to that for
me that basically reads an existing layer definition, uses a bit of DOM
manipulation to swap out the filter element's text, and uses the
modified layerdefinition in a new map.  GetLayerKML should allow a
similar strategy; please let us know how you make out.

Good luck!

Jason

Hi Jason,

Actually, I can use this operations calling directly the agent as well
from
the web extensions API (i.e Java) from the MgKmlService. For my current
project, I need to publish one entire layer and some features from this
layer. For now, publish the layer via MgKmlService::GetLayerKml(...)
works
fine. Otherwise, GetFeaturesKml(...) does not work for me or it does the
same that GetLayerKml.

So, my next step is create a filter for the layer and then call
GetLayerKml
in order to see if it only export the filtered features.

P.D: Sorry for my english.

Thanks.
