Remarks

May be taken as approximate transformation Monte Mario to WGS 84 - see code 1662. For more accurate transformations to explicit realizations of ETRS89 see Monte Mario to IGM95 (4) and Monte Mario to RDN2008 (5), CTs 9733 and 9734.

Frequently Asked Questions

How do I convert Monte Mario to ETRS89 coordinates?

Use the coordinate transformation tool above to convert Monte Mario (EPSG:4265) to ETRS89 (EPSG:4258). Enter your source coordinates and click Transform. This uses the Position Vector transformation (geog2D domain) method with 4m accuracy.

How do I transform Monte Mario to ETRS89 using Proj4js?

Use proj4.defs to define both EPSG:4265 and EPSG:4258, then call proj4(source, target, [x, y]) to convert coordinates programmatically.

What is the accuracy of the Monte Mario to ETRS89 transformation?

This transformation (EPSG:1661) has an accuracy of 4m using the Position Vector transformation (geog2D domain) method. Area of use: Italy - Sardinia onshore.
