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.
