摘　　要：地理信息监测数据基本统计是地理信息监测工作的重要内容。根据地理信息监测采集的点、线、面等几何特征类型和地理实体对象,进行自然地理要素、人文地理要素的数量、密度、位置、高程、范围等内容的统计。地理信息监测基本统计流程分为数据预处理、统计配置、基本统计计算、变化量统计、转移矩阵计算、统计结果生成6个部分。本文结合工作实际,重点探讨省级地理信息监测数据统计方法及关键技术。Basic statistics of geographic information monitoring data is an important part of geographic information monitoring work.According to the geometric feature types such as points,lines,and areas collected by geographic information monitoring and geographic entity objects,the statistics of the number,density,location,elevation,and scope of natural geographic elements and human geographic elements are carried out.The basic statistical process of geographic information monitoring is divided into six parts:data preprocessing,statistical configuration,basic statistical calculation,change amount statistics,transition matrix calculation,and statistical result generation.Based on the actual work,this article focuses on the statistical methods and key technologies of provincial geographic information monitoring data.
