摘要
结合大比例尺地形图数据建库的项目,总结了基于南方CASS成图系统生产的大比例尺地形图数据建库基本原则,对建库过程中的数据分层、数据编码、数据无损转换入库、数据质量控制等几个关键技术作了详细阐述,介绍了建库过程中的注意事项,并通过实际项目生产验证,做到数据无损建库,建库数据质量得到保证,建库效率大大提高。
The basic principles of building database which were based on the large scale topographic maps data with CASS were summarized in combination with the project of building database. Some of the key technologies which contained stratii ed layers, data coding, data lossless conversion, data quality control were studied in detail, and introduced some precautions in the progress of building database. These key technologies which could build database with lossless conversion and ensure the quality of the data and increase the production efficiency greatly were verified in actual project production.
