Abstract
InSAR products are the outcome of processing choices, model assumptions, and the intended use of the data. Thus, different choices inevitably lead to different results. This study revisits the fundamental decisions underlying InSAR parameter estimation, starting from the radar observations and following the complete chain from points, via arcs and networks, to displacement products and their three-dimensional interpretation. It discusses how stochastic and functional models should be defined, how application-aware and application-aligned (triple-A) networks can be constructed, and how displacement estimates can be interpreted in three dimensions. By rethinking these foundations, this work moves beyond generic wide-area products towards interpretable, trustworthy, and actionable InSAR information products.
