LandXML

Starting with TPC Desktop 2015, TPC now reads and writes LandXML files. These are XML data files defined by www.LandXML.org.

LandXML Versions

TPC Desktop 2015 supports LandXML version 1.2, but future versions of TPC Desktop may support future versions of LandXML.

Importing LandXML

When TPC imports a LandXML file, TPC displays a dialog, showing the data it supports in a dialog. You then select the data you want to import.

TPC does not support all LandXML data types, but strives to support the ones you use most often like Points, Parcels, Alignments and Surfaces. If you have a LandXML data type you need, just contact TPC technical support and let them know.

Exporting LandXML

When you export a LandXML file, you can choose to export the entire survey or select data from the survey. In either case, TPC looks at the data you have selected for export and includes a LandXML data object for every TPC data object that can be exported to LandXML.

For example, if you choose to export a single surface to LandXML, TPC adds a single surface object to the LandXML file.

Exporting the entire survey

Exporting selected traverses or points

Traverses as Alignments and Parcels

When TPC exports to a LandXML file, it has to determine which traverses to export as Parcels and which to export as Alignments. It does so with the help of Traverse Groups. Traverses in the Parcels and Lots group are exported as Parcels as long as their closure type is not set to Open or Closed Point To Point (must be Closed or undetermined). Traverses in the Alignments group are exported as alignments.

Units

TPC supports many of the LandXML units. When importing a LandXML file, TPC converts the incoming units to the survey units of the current survey. When exporting a LandXML file, TPC uses the current survey units to determine the units of the exported LandXML file.
