A .NET standard library to read/write shapefile (*.shp, *.shx, *.dbf, *.prj)
Get Started
$ dotnet add package IRI.Maptor.Sta.ShapefileFormatReadme
A comprehensive .NET Standard 2.1 library for reading, writing, and converting ESRI Shapefile formats with advanced geometry support, international character encoding, and coordinate system transformations.
✨ Features
📁 Supported File Formats
- ✔️ SHP - Geometry storage with full ESRI specification compliance
- ✔️ DBF - Attribute data with advanced encoding support
- ✔️ SHX - Shape index for fast spatial queries
- ✔️ PRJ - Projection and coordinate system information
- ✔️ CPG - Code page detection for character encoding
🔷 Geometry Types
| Point Types | Polyline Types | Polygon Types | Multipoint Types |
|---|---|---|---|
| Point | Polyline | Polygon | Multipoint |
| PointM | PolylineM | PolygonM | MultipointM |
| PointZ | PolylineZ | PolygonZ | MultipointZ |
🌍 Advanced Capabilities
- Format Conversion: Seamless conversion between ESRI types and standard formats:
- WKT (Well-Known Text)
- WKB (Well-Known Binary)
- GeoJSON support
- Internationalization: Advanced DBF file encoding support for global character sets
- Performance: Memory-efficient streaming API for large files
- Type Safety: Strongly-typed attribute data handling with custom mapping
- Coordinate Systems: Full projection and coordinate transformation support
- Spatial Indexing: Built-in spatial indexing for fast spatial queries
