ken, met nadruk op een visualisacieomgeving met gekoppelde
vensters. Er blijven echter nog veel onduidelijkheden. Vragen
als: 'Hoeveel van deze gekoppelde vensters kan de gebruiker
verwerken?' 'Begrijpt de gebruiker de kubus nog wel als er
meerdere ruimte-tijd-paden zijn afgebeeld?' 'Hoe moet de in-
terface eruit zien?' De meeste van deze vragen hebben alles van
doen met bruikbaarheidonderzoek, dat overigens in de nabije
toekomst uitgevoerd zal gaan worden. Daarnaast moet men
zieh realiseren dat de kubus niet de oplossing is voor de visu-
alisatie van alle ruimte-djd problemen.

Summary
M.-J. Kraak De ruimte-tijd-kubus bekeken vanuit het
perspectief van de geovisualisatie
Keywords: theoretical cartography, visualisation, research
At the end of the sixties Hägerstrand introduced a space-time
model which included features such as a Space-Time-Path and a
Space-Time-Prism. His model is often seen as the Start of the
time-geography studies. Throughout the years his model has been
applied and improved to understand our movements through
space. Problems studied can be found in dijferent fields of
geography, and ränge from those on an individual movement to
whole theories to optimize transportation. From a visualization
perspective the Space-Time-Cube was the mostprominent element
in Hagerstrand's approach. In its basic appearance it consists of a
eube with on its base a representation of geography (along the x-
and y-axis), while the cube's height represents time (z-axis).
However, when the concept was introduced the options to create
the graphics were limited to manual methods and the user could
only experience the single view created by the draftsperson. Today's
Software has options to automatically create the eube and its
