About LandXML.org

Launched in January, 2000, LandXML.org is committed to providing an non-proprietary data standard (LandXML), driven by an consortium of partners for the inter-operability of data utilized within the Land Development industry.


The goal of LandXML.org is to specify an XML file format for civil engineering design and survey measurement data for the purposes of:

  1. Transferring engineering design data between producers and consumers.
  2. Providing a data format suitable for long-term data archival.
  3. Providing a standard format for electronic design submission.

There is no direct cost to join LandXML.org, nor specific level of participation required.

What is LandXML?
