Hi @Botronics,
Please, try to be more precise. What is not working? Write a small example to reproduce the error. Tell me what do you expect and what's happening. Moreover, in the data folder there are examples how the file should be.

Currently you are supporting input file as gml file in fields2cover_ros, i would like to extend it to support json file.
I see support for it on your library, so i have modified code to import JSON.
f2c::Parser::importGml(field_file, fields_);
to
f2c::Parser::importJson(field_file, fields_);

This was already inside the library. Which is the problem then?

The error is on the transform function. Before it, you need to specify the coordinate system. This is due to json doesn't explicitly say which coordinate system is using. Fortunately GML does.
Just put a line before the transform call and after the import as
field.setEPSGCoordSystem(4326);
field is a F2CField.
