Google maps for crowdsourced emergency routing

Gathering infrastructure data in emergency situations is challenging. The affected by a disaster areas are often large and the needed observations numerous. Spaceborne remote sensing techniques cover large areas but they are of limited use as their field of view may be blocked by clouds, smoke, buildings, highways, etc. Remote sensing products...

3D Spatial Information Infrastructure for the Port of Rotterdam

The maintenance of the complex infrastructure and facilities of Port of Rotterdam is based on large amounts of heterogeneous information. Almost all activities of the Port require spatial information about features above- and under- ground. Current information systems are department and data oriented and cannot reflect the new process- & project...

Balancing Infrastructure and Innovation in Geoinformation-infrastructure projects

Spatial information is increasingly exchanged between organizations within a National Geo Information Infrastructure (NGII). While a lot has been written on implementation strategies, yet little is known what really goes on in concrete projects. In this paper an ethnography is presented based on a narrative approach of a Dutch project, in which...

Toposcopy: A modelling tool for CITYGML

The new 3D standard CityGML has been attracting a lot of attention in the last few years. Many characteristics of the XML-based format make it suitable for storage and exchange of virtual 3D city models. It provides possibilities to store semantic and geometric information and has the potential to incorporate topological models. A large number...

Building a NGII: Balancing between infrastructure and innovation

A multitude of studies has been published on how National Geo Information Infrastructures (NGII), also known as Spatial Data Infrastructures (SDI), should be designed, set up and monitored. Scientific research on day-to-day experiences, on what is really happening in NGIIprojects is hard to find. We propose a narrative approach to elicit...
