Claim:
1. A method of land surveying with electronically registered multi-layer underground and surface images, comprising: orienting, scaling, and registering a first image layer to a standardized orientation and scaling on a map of a photograph of a land surface from a zenith point in space above; orienting, scaling, and registering a second image layer to the standardized orientation and scaling on the map a result of an investigation of buried objects point-by-point in an immediate search area of a corresponding ground surface radio illuminated by a radio broadcast transmitter in the 500-kHz to 1,000-kHz band transmitting from a location outside an immediate search area; orienting, scaling, and registering a third image layer to the standardized orientation and scaling on the map any results of an investigation of sensing together short-wavelength reflections of 100-MHz to 2,000-MHz and long-wavelength scattering of the electro-magnetic radio energy of the radio broadcast transmitter from buried objects underneath in layered soils with a surface-based measurement of buried-object signals using at least a phase-coherent elimination of ground surface reflection noise of at least sixty decibels in digital signal processing with a field programmable gate array (FPGA); and orienting, scaling, and registering a fourth image layer to the standardized orientation and scaling on the map an interpretation of signals and a display of icons and characteristic descriptions of underground utility infrastructures; and registering and overlaying all such other layers together in a global positioning system (GPS) depiction of the land surface and that includes registrations of the first through fourth image layers; wherein, underground buried objects and utilities are located to make safe nearby digging.
