The Study on Error Analysis of Discretization Area in Discrete Global Grid System

open access: yesProcedia Environmental Sciences, 2011
AbstractThe research of area calculation error is the base of discretization of area in discrete global grid system. The error source of discretization of area was analysed and a calculation experiment was designed to calculation the errors of discretization of area. The true area and discretization area were calculated.
