| 摘 要： | 目前，测绘地理信息生产方式还是以传统的大规模、周期性、全要素生产为主，缺少覆盖更新数据采集、处理入库、提取分发、配图切片、发布全过程的数据标准、生产协调机制、工艺流程和支撑软件系统。本文从重要地理信息要素标准、地理信息变化发现、更新生产调度、外业要素采集、数据库更新与发布等地理信息更新全流程进行研究，提出了1∶1万基础地理信息数据及天地图数据动态更新工艺流程和生产组织模式，形成省级地理信息动态更新技术体系。

| Abstract: | At present,production mode of surveying and mapping geographic information is still mainly consist of traditional largescale,periodic and full-feature production methods,which is caused by lacking data standards,production coordination mechanism,technological process and supporting software system for updating data collection,processing and storage,extraction and distribution,mapping and slicing,publishing.This paper studies the entire process of geographic information update from following aspects:important geographic information data standards,geographic information change discovery,production scheduling update,field data collection,database update and publishing,proposes a dynamic updating process and production organization model of 1∶10000 basic geographic information data and"Tianditu"data,with which to form a provincial geographic information dynamic updating technology system. |
