摘要在数字测图技术飞速发展的今天，对于测绘工作者而言，要求的不仅仅是外业的工作效率，而是对于内外业的一体化操作。怎样将内业与外业的联系变得更加紧密，是人们一直在追求的问题。而我们在本文中探讨的是如何使用在外业中的有编码操作使得外业测量而得到的资料可以更好地在内业中加以运用，从而使得测绘工作的一体化操作得以更好地实现。72339

而我们的编码作业与执行对应的是南方CASS软件，是一种基于AUTOCAD开发出来的绘图软件，CASS软件的内部自带编码文件使得我们可以使用或编辑其内部编码来进行有码测量,也就是说将CASS软件内部的简编码应用到数字测图中来。这样的编码测绘作业就可以在内业中通过软件的内部简码识别功能从而自动绘图，可以节省内业工作大量的时间，提高工作效率。

而我们将从数字测图的基本流程开始介绍，着重讲解使用cass简码法进行数字测图有码操作的方法，并通过实验验证其优势性，比较其与原本的草图法的不同，总结应用经验，从而对编码作业对提高数字测图内外业一体化的作用做一个判断。

Research on the internal and external integration of digital mapping

Abstract With the rapid development of digital mapping technology today, for surveying and mapping workers, the requirements of the industry is not only the work efficiency, but for the integration of internal and external operation。 How to become more closely related to the internal and external industry is a question that people have been pursuing。 And we investigate in this paper is how to use the encoding operation makes the measurement and the data can be better industry, to be used in the industry, which makes the work of Surveying and mapping, integration of operations can be better realized。

And our job code and executing the corresponding is South CASS software, is a drawing software based on AutoCAD development, CASS software comes with file encoding allows us to use or modify its internal code to code measurements that will be within the software Cass Jane coding applied to digital surveying and drawing。 This code of Surveying and mapping work can, industry through internal software brevity code recognition and automatic drawing, can save work in the industry a lot of time, improve work efficiency。

First introduced the basic process and we will from the digital mapping and focuses on explaining using Cass brevity code method for digital mapping method of operation code, and the experiment validates the superiority, it is different with the original sketch method, summarize experience, and thus the job code to improve the digital map inside and outside the industry, integration test to do a judgment。

This paper has 6 figures, 3 tables, 20 references。
