Abstract
Due to the limited bandwidth available to mobile devices
transmitting large amount of geographic data over the Internet
to these devices is challenging. Such data is often
high-resolution vector data and is far too detailed with respect
to most location-based services (LBS) user requirements.
A less detailed version may be sent prior to the
complete dataset using a progressive transmission strategy.
Progressive transmission is generally performed by transmitting
a series of independent pre-computed representations of
the original dataset at increasing levels of detail where the
transitions between these levels are not necessarily smooth.
A model is proposed in this paper for selective progressive
transmission which will provide smoother transmission over
increasing levels of detail. We define criteria for the comparison
of similarity between the progressive states of the
vector-data based on shape complexity of the polygon features.
This allows development of a real-time strategy for
the progressive transmission of vector data over the Internet
to mobile devices.
