• Coordinate transformation. Converts coordinates between geodetic, Cartesian, and projected systems. Supports a large number of reference systems and performs calculations with high precision. Transformations include conversions between WGS84, ED50, and national systems.
• Geodetic distance calculation. Determines the distance between two points on an ellipsoid, taking the curvature of the Earth into account. Calculations are based on geodetic formulas such as Vincenty's, ensuring accuracy even over long distances.
• Ellipsoid conversion. Lets you transform coordinates between different reference ellipsoids. Includes parameters for many standard and custom ellipsoids.
• Map projections. Performs Transverse Mercator (UTM), Lambert, and other projections. Configurable for specific zones and custom parameters.
• Area calculation. Calculates the area of polygons on ellipsoidal surfaces. Suitable for cadastral measurements and engineering projects.
• Datum transformation. Applies transformations between geodetic datums using Helmert and Molodensky methods. Supports shifts, rotations, and scaling.
• Coordinate interpolation. Generates intermediate points along geodesic paths. Uses algorithms that maintain accuracy on complex routes.
• Format conversion. Converts between decimal degrees, degrees-minutes-seconds, and radians. Includes rounding and output format options.
• Azimuth calculation. Determines the direction angle between two points on the ellipsoid. Provides results in degrees or radians, with meridian convergence correction.
• Ellipsoidal height. Calculates height above the ellipsoid and works with geoid data to convert between height types. Compatible with geoid models for corrections.
• Coordinate validation. Checks the consistency of coordinates within permitted ranges. Detects errors in latitude, longitude, and height values.
• Grid generation. Creates coordinate grids for surveying projects. Configurable in size, resolution, and reference system.

GeoDLL was developed by KILLETSoft, a company specializing in geodetic solutions. The library is written for Windows and has been updated regularly with new algorithms and support for modern reference systems. GeoDLL integrates with GIS, CAD, and navigation applications through its documented API.
