摘要
为满足数字地形图坐标和高程转换的特殊需要,弥补一些商业软件在地形图转换数学模型上的不足,设计开发了AutoCAD环境中基于图元的VBA数字地形图坐标转换工具,实现数字地形图坐标和高程的全自动转换。
To meet the special needs of digital topographic map coordinate and elevation conversion, tomake up for the mathematical models＇ defect of commercial software in topographic maps coordinate conversation,graphic unit -based VBA digital topographic map coordinate conversion tool in AutoCAD environment isdesigned and developed. Ithas achieved a fully automatic digital topographic map coordinate and elevation conversion.
