Before revision:  In this article, we show how data dependent triangulations with min-error criteria can be used to reconstruct a dynamic surface over a longer time period if height values are continuously monitored at a sparse set of stations and, additionally for few epochs or a single one an accurate reference surface is given.
After revision:  In this article, we show how data dependent triangulations with min-error criteria can be used to reconstruct a dynamic surface over a longer time period , assuming that height anomalies are continuously monitored at a sparse set of stations and, additionally for few epochs or a single one an accurate reference surface is given.
