From 3D City Modelling to 3D Country Modelling: First Tests on Scale-Dependent Rendering on Mobile Devices - Innovations in 3D Geo-Information Sciences - page 70

is unlikely that users will be working with or require a dataset composed of a sin-
gle level of detail—indeed, as discussed above the detail should be adapted to the
specific application and context of use. The potential of 3D generalisation to pro-
vide more context (application) specific data and to address performance issues on
mobile devices should also be further investigated, to ensure that the data provided
is contextually appropriate and presented at a scale that is relevant while meeting
expected performance. However, this work should be carried out in parallel with
usability testing and the enhancement of the techniques prototyped here, to ensure
that the resulting datasets are usable both in terms of overall performance but also
in terms of interaction, localisation and navigation.
