摘　　要：坐标标注常用于标识工程图件的平面坐标位置。当需要标注图件的地理坐标或转换的坐标成果时,传统的标注功能无法满足这些需求。本文根据应用需求,提出将坐标转换功能无缝集成到坐标标注功能中,采用加密狗对转换参数的存储和调用,基于JIG(即时绘图)技术实现了动态标注,极大地提高了标注效率。Coordinate dimensioning is often used to identify the plane coordinate position of engineering drawings.When the geographic coordinates of the map or the coordinate transformation results need to be dimensioned,the traditional dimensioning function can not meet these needs.According to the application requirement,the coordinate conversion function is seamlessly integrated into the coordinate dimensioning function. The dongle is used to store and invoke the conversion parameters. The dynamic dimensioning is realized based on JIG(Just in Time Graphic) technology,which greatly improves the labeling efficiency.
