LandXML.org in a Nutshell
Launched January 2000, LandXML.org is committed to providing an non-proprietary data standard (LandXML), driven by an industry consortium of partners. There is no direct cost to join LandXML.org, nor specific level of participation required.
Once you join, stay informed and participate by using the LandXML discussion email list firstname.lastname@example.org.
Changes for LandXML-2.0 posted January 28, 2016
New build of the free Carlson P3D LandXML Viewer is available, now supports Volume Parcels and embedded objects.
Minor changes have been posted to the proposed LandXML 2.0 schema to support x,y,z scaling of 3D objects.
New LandXML-2.0 samples files with embedded 3D objects and multitextured surfaces are available on the samples page.
Finally, a Free LandXML Viewer is available
After many years of requests by users for a free LandXML viewer, Carlson Software has provided a high quality 3D viewer that has some neat functionality like the ability to add textures to any LandXML file and upgrade it a LandXML-2.0 version file. Another great feature generates 3D image thumbnails automatically in Windows File Explorer, so you can see what the file looks like before opening it. It can also be used as a visualization tool since you can also import OBJ and Sketchup files. download it now and watch the Introduction Video Here
Changes for LandXML-2.0 posted January 19, 2016
New LandXML-2.0 samples files are now available on the samples page. The following changes have been posted to the proposed LandXML 2.0 schema:
- Added multi-color and multi-texture support for Surfaces
- All required texture images are embedded in LandXML file for maximum portability
- Added embedded 2D/3D symbols for CgPoints as encoded DXF
- Added a MaterialTable with display and materials attributes for any CoordGeom, CGPoints, cross sections and surface faces elements. This works for any elements derived from <CoordGeom> and <Point3D>.
- Added a road design cross section template table.
- Added Pond definition to PipeNetworks → Struct element.
- Added Channel definition type to PipeNetworks → Pipe element.
- Adoption of XML digital signature for signing and sealing LandXML instance content.
LandXML 2.0 Highlights

►Support Signing and sealing
►Incorporate 3D Road model improvements from worldwide input.
Add flexible road cross section design template definitions.
Add SCS and Rational runoff associated with surface boundaries.
Sanitary sewer pipes, structures and networks additions.
Storm water open system culverts, ditches, ponds and allow combined closed/open networks.
Add Material Table for element appearance

LandXML 2.0 (Working Draft) Schema Announced
The LandXML 2.0 (Working Draft) Schema and 2.0 HTML (Working Draft) documentation are now available on the LandXML Schema Versions & Specifications page.
Work is underway on the LandXML 2.0 schema plan. The following major objectives are planned and, as always, all feedback is very welcome:
- Update LandXML 2.0 schema based on current standards: XML 1.1, XML Schema 1.1, XML Namspaces 1.1 and xpath 2.0
- Engage OGC and TransXML to improve adjacent standards interoperability for GIS and business process data flow
- Incorporate 3D Road model improvements from worldwide input
- Enhance 3D/volumetric parcel support
- Enhance data model to better suite intelligent construction data flow
- Add flexible road template definitions
- Define a mimetype for compressed (zipped) LandXML files
- Other additions/changes as needed
