Geospatial Types

Cratis provides first-class support for geospatial data in MongoDB using types from Cratis.Geospatial. The serializers follow the GeoJSON standard, making them compatible with MongoDB’s geospatial query operators and external mapping services.

Supported Types

• Point — Single geographic coordinates (longitude, latitude)
• LineString — Routes and paths (ordered sequences of points)
• Polygon — Geographic areas with optional interior boundaries (holes)

GeoJSON Compatibility

All geospatial types are serialized in GeoJSON format, enabling:

• MongoDB Spatial Queries — Use $near, $geoWithin, and other spatial operators
• Interoperability — Work seamlessly with mapping services and GIS tools
• Standards Compliance — Follow industry-standard GeoJSON specification

Getting Started

Choose the type that matches your use case:

• Use Point for storing single locations (stores, users, events)
• Use LineString for routes, paths, or trajectories
• Use Polygon for service areas, regions, or geographic boundaries

See the individual type documentation for implementation examples and best practices.
