Quantitatively optimized selection of proper scale in land use cartographic generalization

Abstract

This paper quantitatively analyzs the map information of different scales in the range of the mapping scale by making use of landscape pattern index, and constructs an evaluation index system by the standard of cartographic generalization evaluation. It takes land use cartographic generalization in Da Xing agricultural region of Beijing for an example, evaluates on the map quality between the scale interval of 10 thousand and 100 thousand, and selects the appropriate scale so as to meet the need of land use cartographic generalization. © 2009 Springer Science+Business Media, LLC.
