摘要
GIS建库数据中系统误差的控制是当前GIS数据质量研究领域的重要方向之一。本文提出一种直接估计系统误差综合效应的黑箱方法, 而传统的仿射变换将成为该法的特例。文中首先阐述黑箱方法的基本原理, 然后根据多元统计学工具建立黑箱校正模型, 最后给出模型辨识和参数辨识的具体方法。
The systematic error control for spatial data in GIS is one of the essential-research issues in the research society.This paper presents a direct rstimation approach for maodeling the integrated effect of the systematic error in GIS data using the black box approach.The traditional affine transformation method turns to be one special case of this the black box apprpach.In this paper,the principle of the black box approach is firstly introduced.The black box correction model is the developed based on the statistics of multi-variables.The methods for model selection and parameter estimation are given finally.
