摘　　要：针对传统测绘研究中,需运用众多测绘软件进行数据处理所导致的操作烦琐、界面复杂等问题,开发了一种基于Python的测绘数据处理辅助软件。该软件实现了模拟数据获取、坐标转换、数据拟合等一系列功能,可有效提高作业效率。主要功能:1)数据模拟。用户可对模拟数据进行参数设置、添加噪声、数据可视化及输出。2)坐标转换。用户单点直接输入或批量输入坐标数据,实现布尔莎七参数模型、平面四参数模型的解算、高斯投影正反算以及对应的坐标转换。3)数据拟合。用户输入待拟合数据,选择线性拟合、多项式拟合、样条拟合等拟合方式,输出拟合参数及对应图像,并进行精度评价。该系统界面友好、操作简单,具有一定的应用价值。In the traditional surveying and mapping research,a Python-based auxiliary software for surveying and mapping data processing is developed to solve the problems of complicated operation and complicated interface caused by the use of many surveying and mapping software for data processing.The software realizes a series of functions such as simulation data acquisition,coordinate transformation and data fitting,which can effectively improve the operational efficiency.Main functions of the system are as follows:(1)data simulation.Users can set parameters,add noise,visualize and output the simulation data.(2)Coordinate transformation.Users can directly input coordinate data at a single point or in batches to realize the solution of Bursar′s seven-parameter model and plane four-parameter model,the forward and backward calculation of Gaussian projection and the corresponding coordinate transformation;(3)Data fitting.Users input the data to be fitted,select linear fitting,polynomial fitting,spline fitting and other fitting methods,output fitting parameters and corresponding images,and evaluate the accuracy.The system has friendly interface,simple operation and certain application value.
