IRI.Maptor.Core
The Sta tier is the heart of Maptor: twelve UI-free core spatial class libraries targeting .NET Standard 2.1 (usable from .NET Core 3.0+/.NET 5+ on any platform). They cover spatial data modeling, geometry algorithms, coordinate reference systems, and file-format I/O, and every project is published to NuGet.
These libraries have no dependency on WPF or any UI framework — the UI layer (IRI.Maptor.Presentation) and the persistence adapters (IRI.Maptor.Infrastructure) build on top of them.
Projects
| Project | NuGet | Target | Description |
|---|---|---|---|
| IRI.Maptor.Core.Common |  |
netstandard2.1 | Foundational primitives and abstractions used by the whole suite: core interfaces and the Point type, linear algebra and statistics helpers, data structures (trees, heaps, disjoint sets), unit conversions, and service models for external map APIs (Google, Bing, Here). |
| IRI.Maptor.Core.Spatial |  |
netstandard2.1 | The core spatial engine: OGC geometry model with typed generics, geometry operations, spatial analysis (Delaunay triangulation, Voronoi diagrams, convex hull, TIN/DTM, IDW interpolation, simplification), spatial indexes (KdTree, RTree), and file-format I/O (see below). |
| IRI.Maptor.Core.SpatialReferenceSystem |  |
netstandard2.1 | Spatial reference systems and map projections: predefined ellipsoids, datum and geodetic transformations, UTM, Mercator/Web Mercator, Lambert and other projections, plus terrestrial, celestial, and orbital coordinate systems. |
| IRI.Maptor.Core.ShapefileFormat |  |
netstandard2.1 | ESRI Shapefile reading, writing, and conversion: SHP/SHX/DBF/PRJ/CPG files, all point, polyline, polygon and multipoint shape types (including M and Z variants), international character encodings, and coordinate transformation on the fly. |
| IRI.Maptor.Core.Ogc |  |
netstandard2.1 | OGC standards support: Simple Features WKT/WKB for all geometry types, GML 2/3, KML/KMZ 2.2, WMS and WFS service models, SLD styling, and Filter Encoding. |
| IRI.Maptor.Core.Graph |  |
netstandard2.1 | Graph data structures (directed/undirected/weighted, adjacency list or matrix) and classic algorithms: BFS, DFS, Dijkstra, Bellman-Ford, Floyd-Warshall, minimum spanning tree, and strongly connected components. |
| IRI.Maptor.Core.Pdf |  |
netstandard2.1 | Vector PDF export of spatial data: single geometries/features, or a decorated print-ready map layout with title, scale bar, graticule, legend and logos, and toggleable PDF layers. |
| IRI.Maptor.Core.MachineLearning |  |
netstandard2.1 | Machine learning and statistics for spatial data: DBSCAN clustering, Apriori association-rule mining, logistic regression, and descriptive statistics. |
| IRI.Maptor.Core.GeoParquet |  |
netstandard2.1 | Reader and writer for the GeoParquet columnar geospatial format. |
| IRI.Maptor.Core.Persistence |  |
netstandard2.1 | Persistence abstractions — data-source interfaces for vector and raster data plus in-memory sources — implemented by the IRI.Maptor.Infrastructure adapters. |
| IRI.Maptor.Core.Security |  |
netstandard2.1 | Cryptography primitives: AES/Rijndael and RSA encryption, signing and verification, hashing (MD5, SHA family), and signed JWT creation/validation. |
| IRI.Maptor.Core.GsmGprs |  |
netstandard2.1 | GSM/GPRS communication: SMS PDU encoding/decoding (SMS-SUBMIT and SMS-DELIVER) and serial-port GSM modem interaction. |
