Icesat full waveform altimetry compared to airborne laser altimetry over the Netherlands

Since 2003 the spaceborne laser altimetry system on board of NASA’s Ice, Cloud and land Elevation Satellite (ICESat) has acquired a large world-wide database of full waveform data organized in 15 products. In this research three products are evaluated over The Netherlands. For this purpose the raw full waveform product, the derived Gaussian...

ICESat Full-Waveform Altimetry Compared to Airborne Laser Scanning Altimetry Over The Netherlands

Since 2003, the full-waveform laser altimetry system onboard NASA's Ice, Cloud and land Elevation Satellite (ICESat) has acquired a worldwide elevation database. ICESat data are widely applied for change detection of ice sheet mass balance, forest structure estimation, and digital terrain model generation of remote areas. ICESat's measurements...

Towards a 3D geo-information standard in the Netherlands

This paper presents the ongoing research project in The Netherlands in which a large number of stakeholders are realising a 3D testbed based on selected use cases and test areas. The findings of the project will result in a Proof of Concept for a 3D Geoinformation standard and a 3D data infrastructure in The Netherlands compatible with...

A 3D model for geo-information in the Netherlands

This paper presents the work in progress of a research project that aims at establishing a reference model for 3D geo-information in the Netherlands. The research project is initiated by four national organizations: 1) Ministry of Housing, Spatial Planning and the Environment, 2) Kadaster, 3) Geonovum, and 4) the Netherlands Geodetic Commission....

Establishing a reference model for 3D geo-information in the Netherlands

This paper presents the work in progress of a research project that aims at establishing a reference model for 3D geoinformation in the Netherlands by extending existing 2D and 3D national and international standards.

Slimme 3D indoormodellen ter ondersteuning van crisismanagement in grote openbare gebouwen

In dit project richten wij ons op het gebrek aan up-to-date 3D indoormodellen voor een groot aantal openbare gebouwen. Deze modellen zijn voor vele stakeholders, maar vooral voor organisaties die zorg moeten dragen voor het managen van de veiligheid van openbare gebouwen, inclusief de BHV (Bedrijfshulpverleners), de brandweer en de...

The variants of an LOD of a 3D building model and their influence on spatial analyses

The level of detail (LOD) of a 3D city model indicates the model's grade and usability. However, there exist multiple valid variants of each LOD. As a consequence, the LOD concept is inconclusive as an instruction for the acquisition of 3D city models. For instance, the top surface of an LOD1 block model may be modelled at the eaves of a...
