一、内容提要：本讲主要讲述变更地籍测量的特点及准备工作、变更地籍测量的分类及测量成果资料的变更的相关内容。

　　二、重点、难点

　　大纲要求：掌握变更地籍测量的概念、内容、分类、方法及特征，宗地分割及调整边界测量放样数据准备及测量，新增界址点放样及测量，宗地合并测量，地籍图及宗地图的变更方法。

　　熟悉变更地籍测量前的资料准备，检查恢复界址点的方法及精度要求，检查宗地面积变更的方法及精度要求，新增宗地的变更地籍测量。

　　了解界址点坐标册、面积汇总统计表及其他资料变更的要求。

　　三、变更地籍测量的特点及准备工作

　　变更地籍测量是在接受变更权属调查移交的资料后，测量变更后的土地权属界线、位置、宗地内部地物地类变化，并计算面积、绘制宗地图、修编地籍图，为变更土地登记或设定土地登记提供依据。

　　1、变更地籍测量的特点

　　（一）区域分散、范围小

　　变更地籍测量一般不进行控制测量及测绘地籍图，而利用原界址点或原控制点作为控制，利用原地籍图作为基础图件。

　　（二）变更地籍测量精度要求高

　　变更地籍测量精度应不低于变更前地籍测量精度。

　　（三）变更地籍测量任务急

　　在接受变更权属调查移交的资料后，应立即进行变更地籍测量，才能满足变更土地登记或设定土地登记的要求。变更权属调查和变更地籍测量，通常由同一个外业组一次性完成。

　　2、变更地籍测量的准备工作

　　（一）资料准备

　　进行变更地籍测量前应准备下述主要资料：原有地籍图和宗地图的复制件；本宗地及邻宗地的变更地籍调查表及原有地籍调查表的复制件（包括宗地草图）；有关界址点坐标数据；必要的变更数据的准备，如宗地分割时放样元素的计算；本宗地附近测量控制点成果，如控制点的坐标、控制点的标记或点位说明、控制点网图等。

　　（二）制定技术方案

　　针对变更地籍测量，宗地变更可分为界址未发生变化的宗地变更、界址发生变化的宗地变更及新增宗地的变更三种情况。变更地籍测量技术方案内容包括：控制点利用及检查恢复界址点方案、新增界址点放样元素计算方法、新增界址点放样方案、界址点测量方案、宗地内部地物地类测量方案、面积计算方法、宗地图绘制方法、地籍图修编及地籍测量成果变更方案。

　　题目：变更地籍测量是在（    ）的基础上进行。
　　A.权属调查
　　B.地籍调查
　　C.变更权属调查
　　D.变更地籍调查
　　答案：（C）

1, Summary: This talk mainly about the changes to the characteristics of cadastral survey and preparation work, change the cadastral survey of the classification and measurement of outcomes data relevant content changes.

Second, focus, and difficult

Outline requirements: to master the concept of cadastral changes, content, classification, methods and characteristics of cases of dismemberment of the measurement and adjustment of the boundary setting-out data preparation and measurement, the new boundary points, lofting and measurement, were to merge measurements, cadastral maps and map cases change method.

Familiar with the changes to cadastral data preparation prior to check-point recovery method and accuracy of boundary requirements, check the area were to change the methods and accuracy requirements, the new cases to changes in cadastral surveys.

Boundary point coordinates volumes about an area of summary tables and other information change request.

Third, change the characteristics of cadastral survey and preparation for

Change the cadastral survey in the acceptance of changes to the transfer of ownership of information, measured after the change of land ownership boundaries, location, were in the internal surface features to class changes, and calculate the area were drawn maps, cadastral map revision, in order to change the land to register or set up to provide the basis of land registration.

1, changing the characteristics of cadastral survey

(A) Regional dispersion, the scope of small

Generally do not change the cadastral surveying and mapping control cadastral maps, while the use of the original boundary points or the original control points as the control, using in situ cadastral maps as a basis for maps.

(B) Change of cadastral high precision

Change the accuracy of cadastral survey should be no less than the accuracy of cadastral surveys prior to the change.

(C) Change urgent task of cadastral survey

In an interview with changes to the transfer of ownership of survey information, shall immediately make changes to cadastral surveying, land registration in order to meet changing or set land registration requirements. Change ownership and changes in cadastral surveys, usually by the same group, one outside the industry to complete.

2, change the preparation of cadastral survey

(A) data preparation

To make changes before the cadastral survey should be prepared to the following key information: the original cadastral maps and the maps were copies; this case and its adjacent land were to change cadastral survey and cadastral survey of the original copy (including the cases to sketch) ; the Boundary point coordinate data; the necessary changes to the data preparation, such as when you were setting out to separate elements of the calculation; this case control points near the measurement results, such as the control point coordinates, control point or a point and the markup description, control point network maps.

(B) to develop technical solutions

Change for the cadastral survey, were to change can be divided into boundary changes were to no change in boundary changes were to change and new cases to changes in three cases. Change cadastral technical programs include: control points and check the use of boundary-point recovery program, the new boundary element method of calculation points, setting-out, the new boundary point lofting program, Boundary-point measurement scheme, were to the internal surface features to classes measurement program, area calculations were method of mapping, cadastral map and cadastral revision to change the outcome of the program.

Title: Change the cadastral survey is in () of the basis.
A. Ownership Survey
B. Cadastral Survey
C. change the ownership of the investigation
D. change the cadastral survey
Answer: (C)
