Grid Squares and Grid Square Statistics

This chapter introduces some examples of Grid Square and Grid Square statistics concepts. The purpose of this chapter is to introduce examples of Grid Square statistics and to help readers deepen their understanding of Grid Square statistics. Grid Square statistics need a standardized Grid Square coding system. This chapter introduces several definitions of Grid Square coding system and compares their strength and weakness. Moreover, we explain the Japanese National Grid Square codes (JIS X0410:2002) standardized in the Japan Industrial Standards (JIS). The Japanese National Grid Square statistics have been developed since the 1960s for both industrial and government usage in Japan. Finally, we show the definition of the World Grid Squares as an extension of JIS X0410:2002 for worldwide usage.
