The Epiphylogenetic Turn and Architecture: In (Tertiary) Memory of Bernard Stiegler

The work of Bernard Stiegler (1952–2020) provides invaluable material for rethinking the built environment as a sort of inorganic spatial memory that enables the evolution of life by means other than organic life. Following Stiegler’s theoretical turn toward epiphylogenetic processes, Footprint 30 is devoted to revisiting the built environment...

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...

Does a Finer Level of Detail of a 3D City Model Bring an Improvement for Estimating Shadows?

3D city models are characterised by the level of detail (LOD), which indicates their spatio-semantic complexity. Modelling data in finer LODs results in visually appealing models and opens the door for more applications, but that is at the expense of increased costs of acquisition, and larger storage footprint. In this paper we investigate...

Automated generalisation within NMAs in 2016

Producing maps and geo-data at different scales is traditionally one of the main tasks of National (and regional) Mapping Agencies (NMAs). The derivation of low-scale maps (i.e. with less detail) from large-scale maps (with more detail), i.e. generalisation, used to be a manual task of cartographers. With the need for more up-to-date data as...
