MongoDB has introduced several new geo capabilities in its 2.4 release, including improved support for geometric processing, non-point geometry storage and querying, inclusion searches on a sphere, intersecting geometries on a sphere, and better support for compound indexes. The new features are designed to improve the performance and functionality of MongoDB's geospatial index. The new geo capabilities conform to the GeoJSON standard, allowing for more flexibility and compatibility with other systems. The new features also enable users to perform complex queries, such as finding routes with start and end locations within specific distances from certain points. Overall, these enhancements aim to provide a more robust and efficient geospatial data storage and querying solution.
