Answer:
Various international standards or codes specify additional secondary values for the description of the load value specific for a location.
For example, the wind load description of the United States according to the code ASCE/SEI 7‑16 specifies various wind speeds for a location, depending on the defined risk category.
The Geo-Zone Tool always uses all location-specific parameters available from the load standard. In addition to the actual primary load value, further parameter maps are carried out in the background. These maps can be selected and displayed in the "Map" list box.
