Autodesk Advances XML for Land Development Industries
LandXML Supported by Industry Leaders

San Rafael, California, January 13, 2000—Autodesk, Inc., today announced that it has developed the initial specifications of LandXML, the extensible markup language (XML) for land development professionals, including surveyors, civil engineers and land developers. LandXML is a common, open data format, or schema, that describes industry-specific data such as points, parcels, and alignments.

Land development professionals worldwide can use LandXML to make the data they create more readily accessible and available to anyone involved with a project. With LandXML, project data is independent of the authoring software, thus overcoming the interoperability problems that have plagued the land development industry. Not only does LandXML provide interoperability between different application software, but also between varying versions of software. As a result, data can be archived and accessed more readily on future projects.

Additionally, other web-based tools can be used to view, edit, and report LandXML data. Extensible Stylesheet Language (XSL) style sheets can be easily created and applied to LandXML data and then run from a project web page. Examples include XSL style sheets that format raw point data into point tables, or format data to match an organization's internal standards, such as legal descriptions for parcel reports.

Autodesk developed the initial specifications of LandXML in close collaboration with several key industry players, who will now serve as the basis for an advisory group to the company as it continues developing the specifications. This group includes Dave Weisberg, publisher and editor of A-E-C Automation Newsletter; software developers Intergraph Civil Engineering, Infrasoft, and Haestad Methods; Nebraska and Florida Departments of Transportation; and consulting organizations including Clough, Harbour & Associates LLP, Vanasse Hangen Brustlin, Inc., and Langan Engineering and Environmental Services, Inc.

"We've been involved for some time now in sharing data between design platforms such as Autodesk's AutoCAD Land Development Desktop and Intergraph's InRoads," said Steven Nieradka, design systems specialist, Clough, Harbour & Associates LLP. "Current conversion methods have always resulted in some data loss, requiring significant time for rebuilding and quality assurance. LandXML promises to enhance our productivity by allowing our design teams and clients to share data across platforms quickly and seamlessly, even from remote locations."

Florida Department of Transportation application software engineer Warren Clary, P.E., explained, "We understand the importance of an open data exchange standard. FDOT is implementing signing and sealing of electronic files, and LandXML will enhance the usability and longevity of this data."

Derived from Earlier EAS-E Industry Initiative Autodesk was a key member of the group of software vendors, design consultants, and DOTs that developed the EAS-E (Engineering And Survey - Exchange) open data exchange format in the 1990s. The EAS-E format created a common standard that provided a clear, easily understood data communication format. "LandXML is the next logical progression for the EAS-E," said Steve Brown, P.E., engineering automation with the Nebraska Department of Transportation. "Now, the LandXML schema evolves the EAS-E format into a full data schema that takes advantage of emerging XML technology."

About XML
XML is an increasingly popular Web standard for businesses. The red-hot technology builds bridges between enterprise applications—the type of links businesses need to power e-commerce ventures—by letting data move easily among them without the incompatibility concerns that have plagued the land development industry. XML on its own merely defines data, which means it must be properly formatted for specific industries such as land development.
