GKProjection class Projections
Grid (Gauss-Krüger) projection representation.
The Gauss-Kruger projection is a cylindrical map projection that is commonly used for large-scale mapping in regions with a north-south orientation. It divides the Earth into zones, each with its own coordinate system, allowing for accurate representation of geographic features.
The Gauss-Kruger projection is currently supported only for countries that use Bessel ellipsoid. Trying to convert to and from Gauss-Kruger projection for other countries will result in a GemError.notSupported error.
