摘要
元数据是一种描述数据的数据,根据各项生产记录整理生成。本文介绍了地理国情监测外业调查元数据的技术规定,并且结合北京市实际情况,利用原始轨迹,探索出了一套"符合国家要求、速度快、精度高、操作性较强"的外业调查元数据制作方法。保证了北京市地理国情监测的合理有效开展,为今后地理国情常态化监测外业调查元数据的整理工作提供一定的技术参考。
Metadata is a kind of data that describes data and generated according to various production records.This paper introduces the technical regulations of field investigation metadata for beijing national geographical conditions monitoring,and combined with the actual situation in Beijing,using the original track,explores a set of ＂in line with national requirements,the high speed,high precision,strong operability＂ methods of making the field investigation metadata.It ensures the reasonable and effective development of the monitoring of Beijing＇s geographical conditions,and provides some technical references for the field investigation metadata of the national geographical conditions monitoring in the future.
