Today early in the morning a person came to talk to us about GPS and mapping, his name is Mr. Steven Schmitdkey from the U.S. CENSUS BUREAU and he brought several items to show us on how to track and how to read and what he does for Work and hobbie. He showed us several different compuses and several information as well on how to work the small GPS Units. It was all confusing at first but when he started to go on more into detail I understood what he was saying and how everything worked.
