Interactive visualization systems allow extensive adjustments of the visualization process, to give the user full control over the visualization result. However, this flexibility increases the complexity of the user interface, impeding the task of finding a suitable set of visualization parameters for a given problem. Visual assistance tools can guide the user in this process, thereby helping to manage the complexity. In this paper, we show how two of such tools, lenses and detectors, can be applied to interactive visualization of remote sensing data.
