摘要
大比例尺数字化测图在测绘生产部门已得到了广泛应用。提高大比例尺数字化测图在数据采集、数据处理方面的效率是值得思考的问题。传统数据采集、数据处理方法单一,效率低下,已不符合当前需求。通过对现有编码法进行改进,结合测绘生产实际,提出有一种自定义规则的新编码法,让使用者易于理解,操作更为方便灵活。新编码法通过"地物码+连接码+辅助码"表示点、线、面、注记之间的相互关系,并利用VBScript对EPS2008进行功能扩展,进一步实现了自动绘图功能。与传统的测图方法相比,新编码法具有测图效率高、生产成本低等特点,更易于在测绘生产部门进行推广。
Large scale digitized mapping has been widely used in surveying and mapping production department,and its efficiency of data acquisition and data processing is an important problem to think about.With simplex and inefficient,traditional data collection,data processing method cannot meet the needs of the surveying and mapping production nowadays.A new coding method with a custom rules that could easily understanding and convenient,flexible proposing is proposed by improving existing coding method which combining with actual production of surveying and mapping.To further implement automatic drawing,the new coding method represents the relationship among the point,line,surface and annotation by using the ground code,the connection code and auxiliary code,and uses VBScript to carry on with the function expansion of EPS2008.Compared with the traditional mapping method,the new coding method has higher efficiency and lower production cost,and is easier to be popularized in surveying and mapping production department.
