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
