GIS在林业应用中造成误差的因素及解决对策

The Cause and Solution of Erros by Application of GIS in Forestry

摘要:

摘要：地理信息系统(Geographic Information Systems）是集计算机学、信息学、测绘遥感学、地质学于一身的新技术系统。随着林业的不断发展，科技富农政策的引导，GIS被引入林业应用中。但是由于GIS在操作使用过程中来自多方面的影响因素，产生了一定的误差。其中原因包括原始数据采集过程中的误差、数据处理中的误差、人为因素造成的误差、GIS自身技术造成误差，笔者针对这些误差因素，根据自身经验提出减小GIS误差的解决对策。

Abstract:

Abstracts:As an new technology system,GIS integrates computer ,informatics, mapping and remote sensing,geology.With the increasing advance of forestry and the guide of “science and technology enriching farmers” policy,GIS has been applied in forestry.Due to multi faceted factors during the application,some errors came forward.They included errors from data collecting,errors from data processing,errors caused by users and errors caused by GIS itself.Based on our practice ,some solution were proposed to reduce errors by application of GIS.
