CoordinateSharp 3.3.1.1 / Magnetic 2.1.3.0

• Added overloads to the ECEF-to-LatLong converters that accept an EagerLoading setting.
• Added overloads to the Cartesian-to-LatLong converters that accept an EagerLoading setting

CoordinateSharp 3.2.1.1 / Magnetic 2.1.2.0

• Expanded solar and lunar eclipse calculation range from 1600 AD–2600 AD to a 3000-year range starting at 0 AD.
• Added corrected eclipse properties and deprecated misspelled properties.
• Improved eclipse calculation accuracy.
• Optimized UTM and MGRS conversion efficiency.
• Refactored celestial calculations for improved efficiency.
• Removed unused code.

CoordinateSharp 3.1.1.1 / Magnetic 2.1.1.0

• Adds support for the World Magnetic Model 2025 (WMM2025), covering the years 2025–2029.
• Introduces constructors that default to the latest WMM, eliminating the need for developers to manually update WMM specifications in their code after upgrading.

//New constructor defaults to latest model WMM2025
Coordinate c = Coordinate(25,25, new DateTime(2025,1,1));
Magnetic m = new Magnetic(c);

3.1.1.1

-Removed deprecated items: This is a breaking change for any projects still referencing obsolete classes or methods.
-Added .NET 9 support: The application now includes full compatibility with .NET 9.
-Extended MoonIllum properties: Added a new moonAge property to the MoonIllum class.
-Enhanced GeoFence point handling: Added the ability to reorder GeoFence points with right-hand or left-hand orientation.
-Added GeoJson support: New functionality to build GeoJson objects directly from GeoFences.

// Create the outer boundary and order (right-handed)
List<GeoFence.Point> outerPoints = new List<GeoFence.Point>

Issue 237

Available on Nuget

2.23.1.1

Adds the ability to densify polylines to mitigate geofence spherical distortions over long distances.

nuget: https://www.nuget.org/packages/CoordinateSharp/2.23.1.1

//Create a four point GeoFence around Utah
List<GeoFence.Point> points = new List<GeoFence.Point>();

points.Add(new GeoFence.Point(41.003444, -109.045223));
points.Add(new GeoFence.Point(41.003444, -102.041524));
points.Add(new GeoFence.Point(36.993076, -102.041524));
points.Add(new GeoFence.Point(36.993076, -109.045223));
points.Add(new GeoFence.Point(41.003444, -109.045223));
      
GeoFence gf = new GeoFence(points);

// Densify the geofence to plot a coordinate every 5 kilometers using Vincenty to account for Earth's shape
gf.Densify(new Distance(5, DistanceType.Kilometers));

2.22.1.1

-Adds Hours of Day DaySpan and Hours of Night NightSpan TimeSpan properties to the CelestialInfo class for easier calculation of total day and night hours for a date at a specified location.

Example:

Coordinate c = new Coordinate(-47, -122, new DateTime(2023, 9, 30));
c.Offset = -7;
         
Console.WriteLine("DAY SPAN: " + c.CelestialInfo.DaySpan.TotalHours); //12.5616666666667
Console.WriteLine("NIGHT SPAN: " + c.CelestialInfo.NightSpan.TotalHours); //11.4383333333333
