Ortus is a Go-based REST service for point queries on GeoPackage files. It allows you to query geographic features that contain a given coordinate using spatial SQLite (SpatiaLite) queries.
SpatiaLite-style spatial SQL for SQLite in pure Rust — PostGIS-compatible ST_ functions, GeoPackage R-tree, CRS transform, H3, MVT. Use via rusqlite, loadable extension, or WASM in the browser
