PREFACE
                      Surveying has been important since the beginning of civilization. Today, the
                  importance  of  measuring  and  monitoring  our  environment  is  becoming
                  increasingly critical as our population expands, land values appreciates, our natural
                  resources dwindle, and human activities continue to pollute our land, water and air.
                  As  a  result,  the  breadth  and  diversity  of  practice  of  surveying,  as  well  as  its
                  importance in modern civilization is increasing from time to time. Surveying is a
                  discipline,  which  encompasses  all  methods  for  measuring,  processing,  and
                  disseminating information about the physical earth and our environment.
