I would say some of the main software out there that kinda integrate BIM in landscape architecture are VectorWorks LandMark and ArchiCAD…..basically in the notion of integrating “intelligent” landscape objects in the design, and linking them to databases of e.g. plants and other elements…..not aware though of how they play a role interoperability-wise with other software or with neutral formats for further manipulation
I guess VW is doing a better job, I think a couple of firms are starting to implement VW LandMark in landscape projects, e.g. PWP LA firm,and Graham LA firm…
If you know more than this, please let me know, I’m very interested in knowing so, as I am a PhD student and researcher, and my interest is in integrating BIM practices in site planning and landscape
