The EPSG Geodetic Parameter Dataset defines 1 transformation between SRGI2013 + INAGeoid2020 v1 height (EPSG:9529) and SRGI2013 + INAGeoid2020 v2 height (EPSG:20043). Its parameters, accuracy and area of use are listed below.

SRGI2013 + INAGeoid2020 v1 height to SRGI2013 + INAGeoid v2 height (1)

EPSG:10616±0.2 m
Method:
Concatenated operation
Area of use:
Indonesia
Scope:
Geodesy, engineering survey, topographic mapping.
  1. SRGI2013 to SRGI2013 + INAGeoid2020 v1 height (1) (null)
  2. SRGI2013 to SRGI2013 + INAGeoid2020 v2 height (1) (null)

In central Java INAGeoid2020 v2 height minus INAGeoid2020 v1 height is approximately +0.2m (v1 surface is above the v2 surface). This difference varies significantly across Indonesia.

Frequently asked questions

How accurate is converting SRGI2013 + INAGeoid2020 v1 height to SRGI2013 + INAGeoid2020 v2 height?
The most accurate official EPSG transformation between these systems is accurate to about ±0.2 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.
