Twelve papers, some of which are drawn from a June 2001 symposium of the same name as the text, address issues the use of geographic information systems and spatial modeling software to environmental or hydrologic problems. The major themes of the papers are: accuracy and uncertainty in spatial dataThe errors correctable with differential GPS are the satellite ephemeris errors, satellite clock errors, and atmospheric errors (ionosphere and troposphere errors ). Errors that are localized to a single receiver are not correctable; these errors areanbsp;...
