112 | Chapter 7 Importing and Exporting Data in LandXML Format

Using the LandXML Import and Export

Commands

LandXML is a data exchange standard for managing data, such as points,

alignment geometry, and other information. It is based on the Extensible

Markup Language (XML), a global standard for exchanging data via the

Internet.

You can use the Import LandXML and Export LandXML commands to export

and import point, surface, alignment, and parcel data in LandXML format,

and to export pipe run data.

By transforming project data to LandXML format, you can do the following:

■ Exchange data. For example, you can import LandXML data into other

software applications that support imported XML. The data can then be

modified and delivered to customers and agencies in the required formats.

■ Transfer and archive data. For example, you can transfer data to another

AutoCAD Land Desktop project, or archive project data in a non-

proprietary format.

■ Create custom reports. For example, you can transform the data into

custom reports by applying XSL style sheets. See the www.landxml.org

website for examples. You can also generate reports using Autodesk

LandXML Reporting, a stand-alone reporting tool that is included with

AutoCAD Land Desktop.

■ Convert units. For example, you can export data from an imperial project,

and then import it into a metric project to scale and convert values.

■ Translate and rotate coordinates. For example, you can use the Import

LandXML and Export LandXML commands to globally adjust the eleva-

tions of project data.

■ Identify project data that has changed. For example, if you change a

project after exporting it, you can use the LandXML Import command

(without actually importing data) to compare the current project to the

exported LandXML file. Any differences between the project data are

listed in the LandXML Import Comparison Results dialog box.

The Import LandXML and Export LandXML commands are based on the

LandXML schema. For more information about the LandXML schema, go to
