The repository root holds the build and CI files and the documentation; everything .NET (the solution, the shared Directory.Build.props and Directory.Packages.props, and the projects below) lives under solutions/. Open solutions/RxSpatial.slnx. The SQL Server projects are archived in solutions/archive/, outside RxSpatial.slnx, so neither a solution build nor CI touches them; open or build them with solutions/archive/RxSpatial.Archive.slnx.
| Path | Platforms | Description |
|---|---|---|
solutions/RxSpatial |
Windows, Linux, macOS | The core library: RxGeography (geodetic) and RxGeometry (planar) moving objects, continuous distance / intersection / intersect queries, and pluggable spatial index backends (list, grid, R*-tree, RUM-tree). |
solutions/RxSpatial.Geo |
Windows, Linux, macOS | The shapes and shape maths the core uses: WGS84 points, exact circles and convex polygons (GeoShape), their planar twins (PlanarShape), and GeoOperations / PlanarOperations (intersects, intersection, distance, area, bounds). Clean-room, zero dependencies. |
solutions/RxSpatial.Index |
Windows, Linux, macOS | R*-tree (Beckmann et al., 1990) and RUM-tree (R-tree with Update Memo, Xiong & Aref) spatial indexes sharing one engine; a clean-room .NET 10 replacement for the formerly vendored LGPL Java ports. Zero dependencies. |
solutions/archive/RxSpatial.SqlServer |
Windows only (archived) | RxSqlGeography and RxSqlGeometry: the same moving objects over Microsoft.SqlServer.Types' SqlGeography / SqlGeometry, for code that must keep SQL Server's types or results (see SQL Server types). |
solutions/RxSpatial.Examples |
Windows, Linux, macOS | Runnable example / smoke test: Rx.NET v7 sequences feeding and consuming RxSpatial streams on every backend. |
solutions/MapRunRxSpatial |
Windows only (WPF) | WPF demo that visualises moving objects and continuous queries on a MapLibre GL JS map hosted in WebView2 (OpenStreetMap tiles, no API key). |
solutions/RxSpatial.Benchmarks |
Windows, Linux, macOS | BenchmarkDotNet suite: per-backend location-update cost, the RxSpatial.Geo operations, geodesic primitives, polygon construction, outlines and multi-core scaling, plus R*-tree vs RUM-tree bulk-insert / update / query comparisons with allocation statistics. |
solutions/archive/RxSpatial.SqlServer.Benchmarks |
Windows only (archived) | The SQL Server baselines: the per-backend workloads through RxSqlGeography / RxSqlGeometry, and each shape operation on SQL Server against RxSpatial.Geo. |
solutions/RxSpatial.Experiments |
Windows, Linux, macOS | Wall-clock harness that reproduces the ICDE 2017 paper's experiments (Figs. 6–12): latency, maximum load and dropped updates under paced location-update streams. |
solutions/RxSpatial.Tests |
Windows, Linux, macOS | MSTest (MSTest.Sdk + Shouldly) tests for the core, the indexes and RxSpatial.Geo, including GeographicLib oracle tests and the fidelity tests against the recorded SQL Server values in solutions/RxSpatial.Tests/Golden. |
solutions/archive/RxSpatial.SqlServer.Tests |
Windows only (archived) | Tests for RxSqlGeography / RxSqlGeometry, the recorder of solutions/RxSpatial.Tests/Golden/*.json, and a guard that live SQL Server still matches it. |
docs/prototypes |
— | Never-compiled 2016 prototype sources, archived with provenance notes. |
