Symbol set for MDPs

MIDOP offer a variety of symbol sets to be used for representing macroseismic intensities on a map.

The followinf sets are available:

• AHEAD
• Arab numbers
• BGS

Here you can see a comparison between these symbol sets.

AHEAD (formerly "NERIES NA4") intensities symbol set

This symbol set is the one officially adopted by AHEAD.

It was first created within the EC Project NERIES Networking Activity 4, and was intended for covering as much as possible the intensity ranges in use in European Institutions.
