Digital Base Map Making Technology on the Underground Pipeline Survey

This paper mainly introduced the digital base map making technology on underground pipeline survey. The article first intro-duced the composition, data format and utilization degree of the multi-source data, which used in the production of the base map, then introduced the data format and data organization of the digital base map. This paper focused on the database file conversion tech-nology, batch attribute processing technology by rule, batch cutting technology. Through independently developing software, rapid production of base map was achieved, and data preparation efficiency was improved.
