1∶10000基础地理信息数据遥感影像解译样本数据库建设探讨

A discussion on the construction of remote sensing image interpretation sample database for 1∶10000 basic geographic information data

1∶10000基础地理信息数据生产主要基于遥感影像进行地理信息解译,由于遥感影像航摄时间、航摄季节及传感器的不同,同一地物遥感影像表达不一致,在数据生产过程中会影响作业人员解译。本研究探索利用近几年的外业调查数据和各类地理要素解译样本建立影像样本库管理系统,用于辅助内业人员对影像判读、提高解译准确性和工作效率。

Production of 1∶10000 basic geographic information data is mainly based on remote sensing image interpretation.Due to the difference in time and season when the image is taken,and different sensors that are used,the expression of the same surface feature will be inconsistent,resulting in difference in the interpretation by operators in the data production process.This study explores the use of field survey data and interpretation samples of various geographical features in recent years to establish an image sample database management system,which is used to assist office workers in image interpretation and improve the accuracy and work efficiency of interpretation.
