Insights from the 4th GML Relay: Advancements and Challenges in Geospatial Data Integration

On January 26, 2006, the 4th GML Relay took place in Emmen, Netherlands, gathering experts from leading companies like Autodesk, Bentley, and ESRI. Building on previous relays, this event focused on practical applications of GML 3 and the new NEN3610 standard. Participants engaged in real-time data transfer exercises, validating schema adherence and exploring the integration of various geospatial tools. With discussions on unique challenges such as 3D representation and topology, attendees aimed for a seamless relay process, paving the way for future advancements in geospatial data handling.

  1. Fourth GML relay (Emmen, 26 January 2006)

  2. 1st GML relay: Univ. Wageningen, NL 12 June 2001 Laser-Scan, Ionic (and Intergraph) 2nd GML relay: TDN, Emmen NL 13 December 2002 Intergraph, eXQte/FME, Bentley, ESRI, Snowflake, Oracle and Laser-Scan

  3. 3rd GML relay: • Delft University of Technology, NL • 17 November 2004 • Autodesk, Bentley, Intergraph, ESRI • and Geodan • Reading of TOP10NL GML did go well • Writing in TOP10NL schema difficult • Not all combinations did work

  4. 4th GML relay: • TD Kadaster, Emmen NL • 26 January 2006 • What is different this time? • Based on GML 3 (ISO standardization) • Based on new NEN3610 (December 2005) • No prototype, but real TOP10NL product • Some off-line practice before live relay • Validation against TOP10NL schema between participants

  5. Participants • Autodesk: Chris Berends, Randy Benjamins • Bentley: Kees van Prooijen, Oscar Custers • Cadcorp: Martin Daly, Martin Schäfer • ESRI: Miloš v. Leeuwen, Rob Kimman • Ionic: Alain Hubert, Bernard Snyers, Bart de Lathouwer • Intergraph: Frank Langelaan and Pieter Jongert • Snowflake/ Eddie Curtis/ MapInfo: Wim Nijmeijer

  6. Procedure today (vendors did receive • GML document on 12 October 2005): • Order of relay will be drawn • Whole GML is read/written in TOP10NL schema, new object inserted (house in empty field) • Files: data1snowflake.xml data2esri.xml, etc • Transfer on USB memory stick • In case of errors no discussion, back to start document (analysis www.gdmc.nl/relay) • Time per participant 25 min alarm bell(first relay, then explain GML developments)

  7. Program 10:00 Registration, coffee, tea 10:30 Welcome Sieb Dijkstra, Director TD Kadaster 10:40 Introduction GML Relay Peter van Oosterom 10:50 Introduction TOP10NL by Nico Bakker 11:20 Relay Part 1 (3 slots) 12:35 Lunch 13:30 GML, NEN3610/2005, TOP10NL Wilko Quak 14:00 Relay Part 2 (2 slots) 14:50 Coffee, tea break 15:10 Relay Part 3 (2 slots) 16:00 Panel discussion 16:30 Conclusion and close, drinks, etc.

  8. Let’s hope it will be a boring relay…

  9. Then it has been a successful event! And some GML3 challenges can be added for the next time: topology, 3D, curves,… Good luck to all participants Now start with the draw for the order
