Method and system for analyzing data error in layered heterogeneous region

The invention provides a method and system for estimating a data error in a layered heterogeneous region; the method comprises the steps: carrying out the layering of a target research region according to the layering index data related to a target observation index, so as to obtain each layered heterogeneous layer; collecting to-be-verified data related to the target observation index from each check point in each layered heterogeneous layer; determining the layering error of each layered heterogeneous layer; and determining the total error of the to-be-verified data according to the layering error of each layered heterogeneous layer. According to the method and the system for estimating the data error in the layered heterogeneous region provided by the invention, the feature space distribution in the target research region for precision verification is fully considered; through a method of firstly carrying out hierarchical error evaluation and then carrying out overall error evaluation, overall precision ev
