Bluedot Innovation, a company providing location-based services, partnered with MongoDB to build a mobile SDK that offers extremely accurate geofencing. The company needed a solution that could quickly and scalably report the nearest geofences, which were of different shapes and dimensions, without significant battery usage. They chose MongoDB's geospatial capabilities due to their fast geospatial index lookup and flexibility granted by the GeoJSON standard, allowing them to offer polygons that fit specific building or outdoor features. The implementation was simple, and MongoDB continued to improve its geospatial queries with performance enhancements in later releases.
