  abstract	= { Multiresolution models are getting more and more
		  importance for a scale--sensitive modelling of spatial
		  data. In principle, they allow the representation of the
		  data at a variety of scales. Of special importance are
		  adaptive methods, where the resolution does not need to be
		  uniform but may be variable. Then, error indicators are
		  used to control the local resolution of the model. In this
		  paper, we show the construction and computation of such
		  error indicators for multiresolution digital elevation
		  models based on recursive triangle bisection for different
		  applications. },
