LandXML to LandGML to GML: Breaking down the Engineering/GIS Data Wall Using Open Standards

This session was very well attended and addressed the LandGML Interoperability Experiment instituted by the OGC, which seeks to advance CAD/GIS interoperability. OGC member ERDC initially envisioned addressing CAD/GIS interoperability via encoding and transformation. ERDC then formed a focus group of members consisting of Galdos, OGC, Autodesk and the “user” with LandXML as the starting point, focusing on enabling a round trip to GML and back without loss. The following is basically taken from the Power Point demonstration:

LandXML is an XML data standard format for civil engineering and survey measurement data used in the Land Development and Transportation Industries. LandGML is a Geography Markup Language Application Schema that can exactly model LandXML 1.0 using GML 3.1.

The primary goal of LandXML was to specify an XML format for civil engineering design and survey measurement data to:

         -Transfer engineering design data between producers and consumers.

         -Provide a data format suitable for long-term data archival.

         -Provide a standard format for electronic design submission.

The LandXML 1.0 schema status is broadly supported in online cadastral applications, GIS applications, survey field instruments, Civil Engineering desktop and CAD-based applications, realtime 3D viewers and high end 3D visualization rendering applications. A wide range of vendors also support it: Autodesk, Bentley, CadCorp, Eagle Point, Safe Software, Trimble Navigation, Leica, Carlson Software and many others. It is also supported in more than 30 software applications and in all major civil engineering software applications in the US.

The LandXML 1.0 schema status also has broad community implementation:

         -Design data standard for US Federal Highway Administration's Interactive Highway Safety Design Model (IHSDM) software.

         -Foundation for transportation industry XML standards.

         -Survey data standard for Land Information New Zealand's Landonline.

         -Emerging in Slovenia as a national 3D road model standard.

         -Used in a Philippine Land Management system.

The LandGML Application Schema was developed by incrementally modeling every single type of element and attribute in LandXML. GML 3.1 was used to express all of the survey and design data model elements as geographic features with “standard” geometries; and attributes as elements where possible. The idea behind this schema is to make it easier for applications that support GML to support LandGML. It doesn't add any new capability, only allows the user to get design data into GML.

A new collaboration between Autodesk and Intergraph's GeoMedia group has recently developed to work on the LandGML Application schema.


The National States Geographic Information Council (NSGIC) recently accepted the GIS Certification Institute's (GISCI) invitation to join the GISCI Board of Governors. This partnership helps to fulfill the goals of both organizations. It was the intention to make the Institute more inclusive in order to better meet the needs of the multidisciplinary GIS profession.

Exor and Laser-Scan announced a partnership to provide network integration tools for the merging and management of linear network data.

GeoAnalytics®, Inc., a provider of geographic and land information systems (GIS/LIS) technology and management consulting, has signed a business partnership agreement with SAS®, the leader in business intelligence.

Leica Geosystems announced that its GIS & Mapping division has recently signed a blanket purchase agreement (BPA) for Leica Geosystems software with the USDA Forest Service. The Forest Service is standardizing on Leica Geosystems imaging processing and photogrammetry software, joining a growing roster of organizations that recognize Leica Geosystems as the premier provider of geospatial imaging solutions.

@Last Software, Inc., a Boulder-based developer of 3D modeling software, announced the ability to exchange files between SketchUp and ArcGIS. This interoperability gives GIS users the ability to create 3D models in SketchUp, incorporate the models in to their GIS database, and then display them in ArcScene and ArcGlobe, ESRI's 3D viewing environments.


Intergraph Mapping and Geospatial Solutions Netherlands successfully participated in the third GML Relay at the "Standards in Action" event held at the Delft University of Technology, the Netherlands. The event demonstrates the easy, open exchange of spatial data using the Open Geospatial Consortium's (OGC) Geographic Markup Language (GML) standard. The GML standard is an XML encoding for spatial data and related attributes used for storing and transporting geospatial information.

Intergraph Mapping and Geospatial Solutions is currently hosting the European Geospatial Intelligence Seminar for the geospatial intelligence community at the Haus der Geschichte in Bonn, Germany. Targeting international military and intelligence decision makers and geospatial intelligence professionals, the seminar focuses on solutions for data management; imagery exploitation; spatial analysis and intensification of data; and dissemination, collaboration and communication of data. Among the briefings offered is a keynote address by Joanne Isham, Deputy Director, National Geospatial-Intelligence Agency (NGA).

ORBIMAGE Inc. announced that it has received notice from the Government Accountability Office ("GAO") that they have dismissed the protest of the NextView Second Vendor contract awarded to ORBIMAGE from the National Geospatial-Intelligence Agency ("NGA"). The protest had been filed by New SI LLC, the competing bidder under the program. ORBIMAGE believes New SI is an affiliate of Space Imaging.

LizardTech, Inc., announced that its next generation MrSID® format (MG3) is now being supported in CARIS product line.

GIS professionals from Utah, ESRI business partners, and ESRI-Denver staff will convene at the GIS EXPO in Salt Lake City, Utah, December 9, 2004. The event will showcase how geographic information system (GIS) technology is used to help Utah businesses and government agencies do their work more efficiently. The GIS EXPO is open to the public and free of charge, however pre-registration is recommended.

The Enterprise for Innovative Geospatial Solutions (EIGS) is pleased to announce that member company Radiance Technologies was recently selected by NASA's Exploration Systems Mission Directorate to support their new vision for space exploration by developing a geospatial technology toolkit for a safe, efficient and effective human return to the Moon and Mars.

Intermap Technologies has announced a new flying program beginning in the spring of 2005 that will extend its NEXTMap Britain 3D landscape map across the whole of the UK. This will mean that for the first time England, Wales, Scotland, Northern Ireland and the Isle of Man will be covered by a single up-to-date landscape survey of unprecedented accuracy.

Euromap GmbH, a wholly owned subsidiary of GAF AG and the DFD installation at Neustrelitz of the German Aerospace Centre (DLR) have started receiving data from the new Indian Remote Sensing Satellite, IRS-P6 Resourcesat-1. The Indian constellation of EO satellites is marketed through ANTRIX, the commercial arm of the Indian Space Research Organisation (ISRO) and Space Imaging, which has obtained international commercial rights. Euromap has entered into an agreement with Antrix and SI to receive and distribute Resourcesat-1 data collected over Europe and North Africa.

The Geospatial Information & Technology Association (GITA) announced that it has launched “Location in Education,” an educational program for middle- and high-school students in the Denver metropolitan area. The announcement was made at the GIS Day celebration hosted by the City and County of Denver on Nov. 17, 2004, at the Webb Municipal Building in Denver, Colo. Jerry Clayton, a teacher at Denver's West High School, and a group of his students were on hand to accept the kit as the program's first participants.
