Nezakladajte rozhodnutie o za\u010dat\u00ed zemn\u00fdch pr\u00e1c na jedinom prejazde. Potvr\u010fte v\u00fdsledky pomocou kr\u00ed\u017eov\u00fdch \u010diar, opakovate\u013en\u00e9ho zobrazovania a ak je to mo\u017en\u00e9, pomocou druhej met\u00f3dy prieskumu.<\/p>\n
GPR zaznamen\u00e1va zmeny v elektromagnetick\u00fdch vlastnostiach zeme.
