ArcGIS 10 and 3D Data processing brochureexplains how ArcGIS 10 (ArcScene) can be used to modify and extend 3D data. 27 July 2010 For some years, iDelft has sold building height data derived from stereophotos. This dataset represents buildings as blocks with flat rooftops. This representation is enough for many applications (e.g. environmental calculations) but insufficient for others (e.g. visualization). For this reason, iDelft has started work to create detailed 3D models derived from laser altimetry data like the Algemene Hoogtemodel Nederland (AHN-2, Dutch General Elevation Model) currently developed by different remote sensing companies. ITC, from Enschede, is helping with this task. More information in the 3D building reconstruction brochure. 16 July 2010 Staff took the iniciative for the webpages: and The sites offer example products and providers. I.e., iDelft shows aerial imagery. 21 May 2010 iDelft announces that new Vector-NL object height and DTM ground levels are available. The data is derived from stereophotos (summer 2008) and is available for the whole Dutch soil (Vector-NL: buildings, greenhouses, vegetation, industry and water; DTM-NL: roads, dykes, railroads, bridges, etc.). The new data is available from today at 28 April 2010 iDelft presents a freeware software package in a 3D Pilot. The 3D pilot is attended by many companies and organisations (e.g. Kadaster, GeoNovum, Buro Toposcopie, TU Delft and Gemeentewerken Rotterdam). De conversion software is developed by iDelft to turn different geographic data into a CityGML 3D file. The software is aimed to create wide area representations of cities and towns. The required data can be obtained through the ordering and a sample can be downloaded from the CityGML site 12 March 2010 The development of a webpage to visualize the location and characteristics of wind turbines in The Netherlands was ordered by Agentschap-NL (SenterNovem, EVD and Octrooicentrum Nederland). .NET and OpenLayers technology was used with OpenStreetMaps data. 12 February 2010 A collaboration between the Ministry of Interior Affairs and Defense has given order to iDelft to deliver digital map data for a websystem. Approximately 500 simultaneous users can access theOpenbare Orde en Veiligheids (OOV) system. iDelft was chosen due to its experience in large scale digital data processing. 29 January 2010 iDelft received a contract from ProRail (the Dutch railway infrastructure authority).
