Danish-specific projection methods based upon the Transverse Mercator projection, to which are applied polynomial-based post-processing applicable to one of three Danish regions. We support three variations:

• Danish System 1934/1945 (non KMS)
• Danish System 1934/1945 (1999 KMS Polynomials)
• Danish System 1934/1945 (2001 KMS Polynomials)

The first two variations have three zones:

1. S34 Jylland
2. S34 Sjælland
3. S45 Bornholm

The last 2001 KMS Polynomial variation was introduced to supersede the 1999 polynomials variations for the S45 Bornholm zone only.
