: Abstract This paper presents the architecture and implementation of a microservice for creating geofences and exporting their coordinates in GeoJSON format. The service allows describing geofences in three ways: (1) by a polygon; (2) by a circle with a given center and radius; and (3) by a circle that is approximated by a polygon. The service provides the ability to populate geofences with geo hashes in order to very quickly calculate which geofence the clients of a locationbased service fall into. Different levels of accuracy and geohash generation strategies are supported. At this stage, the service exports the geofence information in a format adapted for MongoDB database. Experiments have been conducted for different types of geospatial queries with geofences generated by the proposed service (buildings and open spaces of the Technical University of Gabrovo). The experiments show that all types of queries are executed in real time with active 2dsphere database indexing.
