Remarks

IGM95 is the first Italian realization of ETRS89. May be taken as approximate transformation IGM95 to WGS 84 - see code 1099. For accurate transformation to a later realization see IGM95 to RDN2008 (1) (CT code 9737).

Frequently Asked Questions

How do I convert ETRS89-ITA [IGM95] to ETRS89 coordinates?

Use the coordinate transformation tool above to convert ETRS89-ITA [IGM95] (EPSG:4670) to ETRS89 (EPSG:4258). Enter your source coordinates and click Transform. This uses the Geocentric translations (geog2D domain) method with 0.5m accuracy.

How do I transform ETRS89-ITA [IGM95] to ETRS89 using Proj4js?

Use proj4.defs to define both EPSG:4670 and EPSG:4258, then call proj4(source, target, [x, y]) to convert coordinates programmatically.

What is the accuracy of the ETRS89-ITA [IGM95] to ETRS89 transformation?

This transformation (EPSG:1098) has an accuracy of 0.5m using the Geocentric translations (geog2D domain) method. Area of use: Italy - including San Marino and Vatican.
