改进的数字测图方法
Improved digital mapping mode
【摘要】 分析了当前面向点的数据采集方法的优缺点,结合测绘技术提出了既适合外业施工特点又满足对象要求的数字测图方法,并探讨了面向点的数字地图向SPATIAL数据转化的算法设计。
【Abstract】 The paper analyses the disadvantages and advantages of the point-oriented digital mapping way, and puts forward the new way which can be both fit the character of field digital mapping and meet the object-oriented requirements of GIS data. The arithmetic transforming the point-oriented digital map into object-oriented GIS data is also discussed.
