XY is lateral coordinates, Z is either scanner-Z (i.e. height under constant voltage) or voltage (under some sort of constant height, either scanner, or relative to the sample) and value is electrical current between tip and sample. So we have array of either I-V or I-Z spectra in different XY points. I-V can be recalculated to LDoS = (dI/dU)/(I/U), that work for small voltages below 2V, and V gives eV of sample energy levels (we have graph module, that do exactly this).
