I need to find information on determining the resistance of earth between two points located several miles apart. I have found a lot of information on determining the resistance of ground rods to earth, but not on determining what earth itself may look like. Is there anyone out there that can point me at information on what this may look like, taking into account the pertinent factors such as soil type, moisture content, etc.? Thanks in advance...
