Abstract: A trajectory represents an object’s path through space and time. These trajectories are often recorded as a series of spatial positions at discrete time intervals. Depending on the sampling rate employed, there can be a large amount of uncertainty relating to how well the trajectory represents the actual path taken. By using the concept of error ellipses, an adaptive sampling strategy has been developed that allows for the determination of an optimal sampling rate whilst ensuring that a pre-defined uncertainty threshold is not surpassed. This decreasing of uncertainty means that any trajectory derived using the algorithm presented would closely match the actual route taken by the object, thus allowing for more accurate spatial interpretation of the data.

GIS as a technology has come a long way, from the
early adoption of technical wizardry to the ubiquitous,
if unconscious use by the masses. The creation
of the GISociety is on its way through technological
development, theoretical and empirical scientific
research and inclusion of technology into education
with increasing pedagogical justification.
Defining new dimensions of hard- and software,
brainware and orgware are all needed to further
develop the GISociety.
