This automated tool uses techniques modified from Chapman 1999, to detect outliers in latitude, longitude and altitude. Another feature was included to identify possible errors. If the user indicates that the points are "marine" the system will highlight all points that occur inland. Cut and paste your data into the box in the format cited using either a comma (,) or space ( ) to separate individual fields. More information at http://splink.cria.org.br/more_outlier?criaLANG=en.
