MySQL 5.7 offered several new features in addition to the JSON data type, including a vast improvement in geographic information system (GIS) support. MySQL follows the Open Geospatial Consortium (OGC) OpenGIS Implementation Specification for Geographic information - Simple feature access - Part 2: SQL option, which proposes extending the SQL RDBMS to support spatial data.
