基于ADS数据生产数字高程模型关键技术研究

Key Technologies for Producing Digital Elevation Models Based on ADS Data

实景三维龙江建设是未来一段时间内提高全省综合治理能力,形成信息化、智能化治理体系的重要数据,作为新时期测绘地理信息事业的基础性工作,本文以2022年实景三维龙江建设项目为依托,研究基于ADS80数据生产数字高程模型的技术流程,探索数据生产过程中的关键技术。

The construction of 3D real scene in Heilongjiang is an important data to improve the comprehensive management ability of Heilongjiang province and form the information and intelligent management system in the future.As the fundamental work of surveying and mapping geographic information in the new era,this paper studies the technical process of producing digital elevation model(DEM)based on ADS80 data,which is based on the construction of 3D real scene in Heilongjiang project in 2022,explores the key technologies in the data production process.
