Hi Hugh,
Well, you mentioned one of the best ways to get things working - direct
communication.
Richard B. really knows his stuff and set me straigt early on in the LandXML
schema development. When applications get registered, we add that contact
information so we can forward questions like yours to the right vendor.
I am working on improved documentation that explains the details of the
elements and attributes, but that will still not answer your question as too
prefered geometry by specific applications.
I can say that tried and true line, curve and spiral geometry has served us
well. That is by far the most common CoordGeom data type. Adding support for
IrregularLines and Chains is much like handling the Line elements, so it is
pretty straight forward.
We will have a draft of improved documentation by March of 2006. After that
we depend on timely comments to round out the rough spots and fill in the
voids.
cheers,
Nathan

Hi Nathan,
There seem to have been a few emails since this, in particular ones from
Alan Gray.
As Alan has said, my problem is more with the way people interpret LandXML
data, than with the actual schema documentation itself.
The idea of a list of features supported by different vendors would be very
beneficial to us, however my concern is wider than this.
For example when dealing with CoordGeom elements, our software prefers
Chains to IrregularLines. The confusion I had with the InRoads file
involved how best to handle line work. - Breaklines, PlanFeatures or Chains
all being valid options, but I had no idea which was best. - Breaklines was
the answer this time -Thankyou to Richard for helping there :)
You spoke about publishing feature directories on LandXML.org. This would
be great, but I'd like the extra information mentioned above as well!!!
Realistically, do you have a time table for when this may be implemented?
I suspect you have enough other things to do though....
Regards,
Hugh Dixon
