Official EPSG transformation from ID74 to DGN95

The EPSG Geodetic Parameter Dataset defines 1 transformation between ID74 (EPSG:4238) and DGN95 (EPSG:4755). Its parameters, accuracy and area of use are listed below.

ID74 to DGN95 (1)

EPSG:15911±3 m

Method:: Coordinate Frame rotation (geog2D domain)
Area of use:: Indonesia - onshore
Scope:: Transformation of coordinates at 3m level of accuracy.

Parameter	Value	Unit
X-axis translation(tx)	-1.977	metre
Y-axis translation(ty)	-13.06	metre
Z-axis translation(tz)	-9.993	metre
X-axis rotation(rx)	-0.364	arc-second
Y-axis rotation(ry)	-0.254	arc-second
Z-axis rotation(rz)	-0.689	arc-second
Scale difference(ds)	-1.037	parts per million

Derived at 38 stations. Standard deviations of translations are 1.3, 1.1 and 3.6m, of rotations 0.11, 0.06 and 0.04 sec and ppm 0.18. May be taken as a tfm ID74 to WGS 84 - see tfm 1833.

Frequently asked questions

How accurate is converting ID74 to DGN95?: The most accurate official EPSG transformation between these systems is accurate to about ±3 m within its stated area of use. Browser-based converters approximate datum shifts with Helmert parameters; for surveying-grade work apply the official transformation in a desktop GIS.
Does my data leave the browser when I use this converter?: No. All coordinate transformations are computed locally in your browser using proj4js. The coordinates you enter are never transmitted to any server.
