I want to convert autoware sample moriama ROS data XYZ values (-14809, -84683, 37) to utm coordinates. Any leads on this ?

edit

To give a starting point, the coordinates are in Japanese Plane Rectangular CS system, I haven't worked with autoware for a while but there used to be an option in the online map viewer (https://tools.tier4.jp/) but i am unsure if it converts the coordinates.

I recommend using GeographicLib to perform the conversion. One part of the conversion is probably UTMUPS. However, you'll probably need another conversion first. Hope this gets you started.

Use ASSURE mapping tool. In the options dialog use "+proj=tmerc +lat_0=36 +lon_0=137.1666666666667 +k=0.9999 +x_0=0 +y_0=0 +ellps=GRS80 +towgs84=0" as the projection string.

Regards,
