How to start:
Click point on map to obtain SK-42 XY coordinates. WGS84 lat/lon also will be provided in decimal degrees

How it works:
  • The ST_Transform() method from postgis is used for coordinate conversion.
  • Coordinate transformations are available for the territory of the countries of the former USSR and adjacent areas (where SK-42 was mainly used)
  • The inaccuracy of conversion can reach tens of meters (mountainous areas), usually a few meters.
