IRI.Maptor.Core.Spatial

NuGet Target

The core spatial engine of the Maptor stack. Provides the Geometry<T> model, spatial analysis algorithms, spatial indexes, and a wide range of geospatial format I/O — all UI-free and netstandard2.1-compatible.

Installation

dotnet add package IRI.Maptor.Core.Spatial

Features

  • OGC geometry model via Geometry<T>: point, linestring, polygon, their multi-variants, and geometry collections, with WKT/WKB round-trip (FromWkt, FromWkb)
  • Feature model: Feature<T> and FeatureSet<T> with fields and change tracking
  • Spatial analysis: Delaunay triangulation, Voronoi diagrams, convex hull, area statistics, topology helpers, and shape characteristics metrics
  • Line simplification: Ramer-Douglas-Peucker, Visvalingam-Whyatt, and other point-reduction methods, plus simplification quality metrics
  • Digital terrain modeling: regular (grid) and irregular (TIN) DTMs
  • Spatial interpolation: inverse distance weighting (IDW)
  • Space-filling curves: Hilbert and Z-order (Morton) point ordering
  • Spatial indexes: k-d tree (plain and balanced), R-tree, and space-filling-curve R-tree
  • Map sheet/tile indexes for geodetic and UTM grids
  • Format I/O (see table below)

Format I/O

Format Read Write Notes
GeoJSON Yes Yes Geometries, features, feature sets
WKT / WKB (OGC SFA) Yes Yes
TopoJSON Yes Yes Topology encoding and quantization
DXF Yes Yes AutoCAD interchange with styling
SVG Yes Yes
EPS Yes Yes
GPX Yes Yes Waypoints, routes, tracks
PMTiles Yes Yes Serverless tile archive (v3)
SQL Server native binary Yes Yes MS-SSCLRT spatial binary
Vector tiles (MVT) Yes No
Cesium terrain Yes No quantized-mesh-1.0 and heightmap-1.0; writing not implemented
GeoTIFF Yes No Georeferenced raster
GRD Yes No Grid raster format
ESRI JSON Yes No ArcGIS REST JSON geometry
PRJ Yes No ESRI projection WKT

Shapefiles are handled by the companion package IRI.Maptor.Core.ShapefileFormat; KML/KMZ by IRI.Maptor.Core.Ogc; MBTiles/GeoPackage by IRI.Maptor.Infrastructure.Sqlite.

Usage

using IRI.Maptor.Core.Common.Primitives;
using IRI.Maptor.Core.Spatial.Analysis;
using IRI.Maptor.Core.Spatial.Primitives;
using IRI.Maptor.Extensions;

var points = new List<Point> { new Point(51.33, 35.70), new Point(51.42, 35.75) };

// note: (List<T> points, int srid) is the only valid overload
var line = Geometry<Point>.CreatePointOrLineString(points, srid: 4326);

// per-segment lengths on the ellipsoid
double meters = SpatialUtility.GetEllipsoidalLength(points[0], points[1]);

// export to GeoJSON
string geoJson = line.AsGeoJson().Serialize(indented: true);

// WKT round-trip
var parsed = Geometry<Point>.FromWkt("POINT (51.39 35.69)", 4326);
