In this paper, we have designed a data model for moving objects and implemented it. The moving objects are time-evolving spatial
objects, that is, their geometries are dynamically changed as time var...

This paper explores a novel approach to the extraction of spatial objects from the laser-scanning data using an unsupervised
clustering technique. The technique, namely self-organizing maps (SOM), c...
