Setting a custom coordinate reference system

In this recipe, you will define a custom projected coordinate reference system. Your CRS will have the following parameters:

  • A geodetic datum:
    • The reference ellipsoid is at Krassowsky 1940 (semi-major axis: 6378245.000 m and inverse flattening: 298.3)
    • The fundamental astronomic point at the Pulkovo observatory with the latitude 59°46'18.550"N and longitude 30°19'42.090"E
    • Prime Meridian at Greenwich.
  • Projection: A conformal azimuthal perspective projection (stereographic), it is also an oblique stereographic projection on a secant projection plane, with the following parameters:
    • Latitude and longitude of origin (projection pole = center of projection) are φ0 = 460 N and λ0 = 250 E
    • Scale factor (rectangular ...
