Training Description
This training was held in collaboration with the Ministry of Environment and Natural Resources (MARN), El Salvador, and the System of Latin American Integration (SICA) organization to strengthen capabilities in using SAR in monitoring hazards related to flooding and landslides. The focus of the training was put on topics such as accessing SAR data, interpretation of SAR image time series, change detection, and InSAR time series analysis. In hands-on data processing labs, these techniques were applied to the monitoring of a recent flooding event in South Asia as well as an active landslide in California.
