System and method for generating a map for electromagnetic navigation

A system for generating a high density (HD) map for electromagnetic (EM) navigation, the apparatus comprising:

• an antenna assembly configured to radiate an EM field within an EM volume;
• a processor;
• and
• a memory storing processor-executable instructions that, when executed by the processor, cause the processor to:
• receive a measured EM field strength at each gridpoint of a first plurality of gridpoints of the EM volume;
• calculate a theoretical EM field strength at each gridpoint of a second plurality of gridpoints of the EM volume, the second plurality of gridpoints including each gridpoint of the first plurality of gridpoints and at least one additional gridpoint not included in the first plurality of gridpoints;
• and
• combine the measured EM field strength at each gridpoint of the first plurality of gridpoints with a theoretical EM field strength calculation at each gridpoint of the second plurality of gridpoints.
