This is the count of number of points from the earthquakes layer that fall within each polygon. To get our answer, we can simply sort the table by PNTCNT field and the country with highest count will be our answer. Click 2-times on the PNTCNT column to get it sorted in descending ...
The Create Buffers tool creates polygon buffers around points, lines and polygons.This tool expresses buffer sizes as absolute linear distance units (miles, feet, meters, kilometers defined by WGS 84 great circle distance) rather than map units. The haversine formula is used to approximate meaning...
