| Abstract: | The basic unit is the smallest change object of elements in land survey database updating.It was obtained from the overlap of features in two different periods,which reflect the change from one time to another.After the rounding operation,the length of linear features in the basic unit is not equal to the sum or difference of before and after lengths.It leads to logical inconsistency,which should be adjusted.Analyzed the basic adjustment criteria and methods of linear features in the basic unit,refined the ... |
