Marqdouj.DotNet.Web.JsInterop.GeoJson 10.7.0

DotNet.Web.JsInterop.GeoJson

A .NET library for working with GeoJSON data in JavaScript interop scenarios.

Features

• Provides a set of classes and methods for parsing, manipulating, and generating GeoJSON data.
• Supports various GeoJSON types, including Point, MultiPoint, LineString, MultiLineString, Polygon, MultiPolygon, GeometryCollection, Feature, and FeatureCollection.

Serialization

• All GeoJSON types can be serialized to JSON format using the built-in System.Text.Json library, except GeometryCollection which requires special handling.
  • A default ToJson method is provided for each type.
  • GeometryCollection. This type requires special handling during serialization, as it contains a collection of geometries that can be of any GeoJSON type. The default ToJson method implements the requirements to correctly serialize a GeometryCollection.

Deserialization

• All GeoJSON types can be serialized to JSON format using the built-in System.Text.Json library, except GeometryCollection which requires special handling.
• A default FromJson method is provided for each type.
• GeometryCollection. This type requires special handling during deserialization, as it contains a collection of geometries that can be of any GeoJSON type. The default FromJson method implements the requirements to correctly deserialize a GeometryCollection.

Usage

• See the Sandbox project in the source code for examples of how to use the library in a Blazor application.

Release Notes

• v10.7.0

  • GeoJsonProperties. A second constructor has been added that allows you to specify StringComparer.

• v10.6.2

  • Feature.Id. Default is now a Guid string.

• v10.6.1

  • IFeature. Add Id to interface.

• v10.6.0

  • Pixel/IPixel. New object/interface for a Pixel.

• v10.5.2

  • Interfaces. Added interfaces to all IGeoJSON objects to identify their specific types.
    • Helps with type checking and casting of types, especially when working with c# Generics.
    • The new interfaces are:
      • IFeature, IFeature{G, P}: IFeature where G : Geometry.
      • IFeatureCollection, IFeatureCollection{G, P} : IFeatureCollection where G : Geometry.
      • IGeometryCollection.
      • ILineString.
      • IMultiLineString.
      • IMultiPoint.
      • IMultiPolygon.
      • IPoint.
      • IPolygon.
      • IPosition.

• v10.5.1

  • IGeoJsonObject. Interface added to identify objects that derive from GeoJsonObject.
    • Helps with type checking and casting of types, especially when working with c# Generics.
  • IGeoJSON. Interface added to identify objects used in GeoJSON operations. Includes Position, IGeoJsonObject and IGeometry.
    • Helps with type checking and casting of types, especially when working with c# Generics.

• v10.5.0

  • IGeometry interface added to the Geometry base class. Helps with type checking and casting of geometry types, especially when working with c# Generics.

• v10.4.0

  • Update NuGet packages.

• v10.3.1

  • Position. Added ToString(string format) method.

• v10.3.0

  • Changed method signature FeatureCollection<T, GeoJsonProperties>? FromJson<T> to FeatureCollection<T, P>? FromJson<T>.

• v10.2.1

  • Update NuGet packages.

• v10.2.0

  • Added interface IBoundingBoxEdit for editing BoundingBox instances.

• v10.1.1

  • Update NuGet packages.

• v10.1.0
