You cannot make the earth's magnetic field disappear,
so while performing magnetic field mappings can the earth's field
impact my results? if any at all?
In Mapping magnetic fields where are they the strongest and
weakest?
The earth's magnetic field is quite weak when compared to your magnet of consideration, it really depends upon how accurate you want your field lines to be mapped, if the magnet that you are considering had strength which is less than even earth's field then it will surely affect your mappings, but usually its not the case.
