    This thesis explores the acquisition of spatial knowledge as a means to support wayfinding in virtual environments. Specifically, the thesis presents an investigation into
    the potential benefits one might gain through the application of a variety of tools, each of
    which has been designed to support one of the three stages of cognitive map development
    - landmark-based representation, route-based representation, and survey-based
    representation (Siegel & White, 1975). Each tool has been evaluated with respect to
    improvements in wayfinding, and also in their support for environmental learning.
    Measures were taken of each tool used in isolation, and also when used together as a
    complete toolset.

    The between-subjects evaluation process involved 101 participants, randomly assigned to
    one of five conditions. Each participant was asked to navigate a virtual environment to
    locate three specific items. To evaluate wayfinding, participants were asked to perform
    the same task on six occasions within the same session. After discovering all items, a
    measure indicating route efficiency was recorded. On completing all six trials participants
    were asked to produce a map of the virtual environment. It was hypothesised that the
    presence of tools would improve the acquisition of spatial knowledge, and thus route
    efficiency and map production.

    Comparing the 'no-tool' and the 'all tool' conditions, a 2x6 repeated measures ANOVA
    found that when providing the tools concurrently there was a statistically significant
    improvement in the efficiency of route taken (F(1,38)=4.63, p<0.05). However, when
    evaluating the tools in isolation, no significant improvement in route efficiency was
    found. Also, no significant difference between conditions was identified when comparing
    the quality of maps produced by participants across conditions. The thesis concludes by
    arguing that the application of the complete toolset benefits wayfinding, although it is
    noted that the evidence does not support the hypothesis that this is caused by improved
    spatial learning.
