CASS6．1地形、地籍成图软件是基于AUTOCAD平台技术的数字化测绘数据采集系统,广泛应用于地形成图、地籍成图、工程测量三大领域。外业采用全站仪采集测点数据,测量精度可靠,而且省去了人工读数、计算、展点等绘图程序,消除了人为的误差来源,减轻了测站人员的劳动强度,工作效率大大提高。内业利用CASS6．1数字化自动成图软件系统,地物符号规范统一,地形图中等高线是由计算机自动勾绘的,生成的等高线精度较高。
CASS6.1 terrain and cadastral mapping software is a digital mapping data acquisition system based on AUTOCAD platform technology, which is widely used in three fields of terrain mapping, cadastral mapping and engineering surveying. The field uses the total station to collect the measuring point data, the measurement precision is reliable, and omits the drawing procedure such as the artificial reading, the calculation, the exhibition point, eliminates the artificial source of error, reduces the labor intensity of the station personnel, the work efficiency greatly enhances . The CASS6.1 digital automated mapping software system is used in the field. The symbols of the objects and objects are unified. The contour lines in the topographic map are automatically drawn by the computer and the generated contour lines have higher accuracy.
