Abstract: At present, production mode of surveying and mapping geographic information is still mainly consist of traditional large-scale, 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∶10 000 basic geographic information data and “Tianditu” data, with which to form a provincial geographic information dynamic updating technology system.

Key words: geographic information, dynamic updating, production organization model, provincial, updating technology
