合成孔径雷达和干涉合成孔径雷达数据由于其“全天候”能力和传感器的昼夜访问，具有很大的变化探测潜力。在这里，我们调查的潜力和方法，森林风暴，洪水和雪崩映射ERS 1/2数据。在我们的方法过程模型被用来描述的目标之前，期间和/或之后的危险事件。非常重要的是良好的相对校准和不同信息层的精确配准。结果表明，多时相合成孔径雷达和干涉合成孔径雷达数据在灾害制图方面具有良好的潜力。
SAR and InSAR data have a high potential for change detection due to their "all weather" capability and the day/night access of the sensors. Here we investigate the potential and methodology for forest storm, flood, and avalanche mapping with ERS1/2 data. In our methodology process models are used to describe the targets before, during and/or after the hazard event. Very important are the good relative calibration and accurate coregistration of the different information layers. The presented results demonstrate the good potential of multitemporal SAR and InSAR data for hazard mapping.
