Summary
EFAS v4.1 is a change in the EFAS Flash Flood (ERIC) layer and general bug fixes.
Here is a a summary of the main changes:
- New criteria for plotting ERIC reporting points. They are now:
- Catchments of less than 2000km2 (same threshold as before)
- 30% of the ensemble forecast a flood magnitude threshold greater or equal to the 5yr return period threshold (it was 10% only for EFAS v4.0)
- Bugfix to the method to calculate the lead time in the ERIC reporting points
- Generate a spatial index file (.qix) with the ERIC reporting points to speed up the visualisation of the layer on EFAS-IS
