An ethics assessment list for geoinformation ecosystems: revisiting the integrated geospatial information framework of the United Nations

To achieve sustainable development goals, georeferenced data and geographic information systems play a crucial role. Yet, the way in which these data and systems are summoned upon rests on positivist assumptions which overlook both epistemological and ethical concerns. This is epitomized by the integrated geospatial information framework ...

Bi-temporal foundation for LADM v2: Fusing event and state based modelling of Land administration data 2D and 3D

The prime purpose of Cadastral data – whether in the form of maps, survey plans or notes, or a digital database is the definitive demarcation of the extent of properties – and can be seen primarily as a decision support facility (“Can a structure be built here?”, “Where can I build a fence?”, “Should I buy this property”?). There are, however...

A Suggested Terminology for Point-Like Entities in a Bi-Temporal Representation of 2D and 3D Land Administration Data

The prime purpose of Cadastral data – whether in the form of maps, survey plans or notes, or a digital database is the definitive demarcation of the extent of properties – and can be seen primarily as a decision support facility (“Can a structure be built here?”, “Where can I build a fence?”, “Should I buy this property”?).

FIG publication 3D Cadastres Best Practices

At the end the two most recent 4-year terms (2010-2014 and 2014-2018) of the joint commission 3 and commission 7 FIG Working Group on 3D Cadastres, it was decided to collect the best known practices in a single FIG publication. Key authors were invited to lead a chapter on one of the following topics:<br/>- Chapter 1 Legal foundations (Dimitrios...

Applications of 3D City Models: State of the Art Review

In the last decades, 3D city models appear to have been predominantly used for visualisation; however, today they are being increasingly employed in a number of domains and for a large range of tasks beyond visualisation. In this paper, we seek to understand and document the state of the art regarding the utilisation of 3D city models across...

Taming Technology: The narrative anchor reconciling time, territory and technology in geoinformation infrastructures

It is often assumed that innovative technology is an essential resource for the establishment of an information infrastructure. This study on geoinformation infrastructures convincingly demonstrates that technology is an important and far more complex factor than much geoinformation practitioners want us to believe. Three Dutch cases were...

3D topography: A simplicial complex-based solution in a spatial DBMS

Current topographic products are usually limited to a real world representation in only two dimensions, extended with some additional point heights and contour lines. Many environmental issues require more precision than analysis on 2D models can offer. At the same time, vast amounts of 3D data are becoming available due to emerging new data...
