摘　　要：从工作实际需求出发,通过深入分析广州地形图图式与国家地形图图式的异同以及EPS平台与CASS平台数据结构差异,以需求为导向,利用EPS平台的二次开发、模版定制等技术,探索“图式规范+数据平台技术”模式方法,在EPS平台下实现了广州图式EPS*edb数据至国家图式CASS*dwg数据的高效无损转换。生产实践证明所研究的转换工作方法模式能快速实现1∶500大比例尺地形图广州图式到国家图式的快速无损转换,提高了作业生产效率及数据共享利用率,保障了数据转换的质量,为类似项目提供有益的参考与借鉴。Based on a thorough analysis on the similarities and differences between Guangzhou topographic map schema and national topographic map schema,as well as the data disparities between EPS platform and CASS platform,this work successfully achieves efficient and lossless conversion of Guangzhou schema EPS*edb data to national schema CASS*dwg data under the EPS platform via employing technologies like the secondary development of EPS platform and template customization.Extensive production practice proves that this conversion method model enables the rapid and accurate conversion of 1∶500 large-scale topographic maps from Guangzhou schema to the national schema.This proposed data conversion techniques with high practical and popularization value in this work not only enable enhance the production efficiency and utilization rate of data sharing,but also ensure the quality of data conversion.
