OLD-STYLE

VALIDATION CASE

FOCUSED ON: M1 (ONLY VAL), REF DATA, PLURAL M3

LESS FOCUSED ON: ALTERN METHODS, SAT IMG

SEARCH QUAL/COST/TIME, COMPAR EMS-OTHERS

Effective detection of the landslides by Copernicus-EMS Rapid Mapping products Use of ancillary data (UAV and field data) proved to be useful to detect landslides

Both users proficiently used the products and recommend their use

Satellite images show some distorsion and need to be recalibrated A higher resolution satellite imagery (VHR1) is recommended to exclude fake landslides Better field survey planning and use of devices needed, use of smartphones suggested

Both users suggested providing also non-interpreted satellite image as product Both users suggested including a first quick-and-dirty provision of raw delineation maps

Technical EndUser was not completely satisfied of the products

No grading could be assessed for transportation and settlement damages Both users recommend improving the readability of the crisis layers

Need of a higher-resolution DEM to provide a better delineation of landslides
