🌍 Maptor Spatial Library

A .NET Library for Spatial Data Modeling, Transfer, Processing, and Visualization

Maptor is an open-source .NET GIS library designed to make spatial operations, geospatial data processing, and map visualization easy and efficient.
Built for .NET 8+, it provides a comprehensive set of tools for geometry operations, coordinate transformations, raster & vector data handling, and OGC standards support.

✨ Key Features

✅ Spatial Reference Systems (SRS) – Coordinate transformations (WGS84, UTM, Mercator, WebMercator, custom SRIDs)
✅ Geometry Operations – Points, Lines, Polygons, MultiPoints, MultiLines, MultiPolygons.
✅ Geodetic Calculations – Distance, azimuth, and area computations.
✅ Raster & Vector I/O – Shapefiles, GeoJSON, SQL Server, PostgreSQL, Personal GDB, GPX, WKB, WKT, and raster support.
✅ Graph algorithms – BFS, DFS, Minimum spanning tree, Dijkstra, MinCut, FloydWarshall.
✅ OGC Standards - WKB, WKT, WFS, WMS, GML 2, GML 3.
✅ Database integration - SQL Server Spatial, PostGIS
✅ WPF-based map viewer for desktop apps
