What Are the Different Types of Land Surveyor Services?

Cadastral survey is part of the work of cadastral survey. Cadastral survey includes land ownership survey and cadastral survey. The cadastral survey is based on the legal procedures prescribed by the state and based on the land registration application. Through land tenure survey and cadastral survey, find out the ownership, boundary, area, use and location of each land, form survey data such as cadastral survey data, maps, etc., and prepare for land registration and certificate issuance Technical preparations. ^[1]

Cadastral and topographic elements

In order to meet the needs of cadastral management, on the basis of land tenure investigation, using instruments and scientific methods, within a certain area, measure the ownership boundary, location, shape and land type of each land, and calculate its area. draw

1. It is not advisable to repeatedly establish a measurement organization

All provinces, cities, and districts have surveying and mapping teams, which should be properly organized to fully mobilize enthusiasm in all aspects, make overall arrangements, and divide labor and cooperation to complete this task without having to start another stove. (Not to mention individual units are still working)

2. Relevant departments should jointly set up a cadastral survey leading group, which is responsible for organizing cadastral surveys in a province, city, and county. It is impossible for any unit (even the largest surveying and mapping unit in the local area) to contract such a large system project. It is reported that Beijing initially planned that five or six hundred people would have to work five or six years before it could be completed. Therefore, joint operations are required.

3 Organizing joint cooperation accounts for five steps to study carefully:

(1) Investigate the measurement capabilities that this region can undertake for this task;

(2) All units in the survey can draw out the number of cadastral surveys (especially the quality-the quality of people) who are out of production;

(3) This group of people must undergo unified training, learn uniform cadastral survey specifications, and undergo a period of internship to pass the assessment and issue a job certificate;

(4) After the team is established, an agreement is signed according to the economic contracting responsibility system;

(5) For each achievement, the finished products are uniformly checked and accepted in accordance with the comprehensive quality management method to ensure that the cadastral survey task is completed on time and with quality. ^[2]

Cadastral surveys are significantly different from basic surveys and professional surveys. Their essential manifestations are different. All surveys involving the rights of land and its attachments can be regarded as cadastral surveys, as follows:

(1) Cadastral survey is a basic surveying and mapping work with government actions, and is a legally significant administrative technical act in which the government exercises the function of land administration. In foreign countries, cadastral surveys are called official surveying and mapping. In our country, all previous cadastral surveys were ordered by the court or the government. The purpose is to ensure the government's taxation of land and protect the property rights of individuals. The fundamental purpose of the cadastral survey in China at this stage is for the state to provide basic information for social development and national economic planning in order to protect land, rationally use land, and protect the legitimate rights and interests of land owners and land users.

(2) Cadastral survey provides an accurate and reliable geographic reference system for land management. From the history of cadastral and the history of cadastral survey, it can be known that surveying and mapping technology has always been one of the basic technologies of cadastral technology. Cadastral surveying technology not only provides accurate, reliable data that can be accepted by legal facts for land taxation and property rights protection, but also uses modern The advanced surveying and mapping technology provides a legally meaningful geographic reference system for cadastrals.

(3) Cadastral surveys are performed on the basis of cadastral surveys. Based on a comprehensive analysis of complete cadastral survey data, it selects different cadastral surveying techniques and methods. The cadastral survey results provide different forms of maps, numbers, books and other materials according to land management and real estate management or other related requirements.

(4) The cadastral survey has the legal characteristics of investigation and evidence collection. Regardless of the initial registration of property rights, the registration of changes, or the registration of other rights, in the process of reviewing, confirming, and disposing of land rights, the work done by cadastral surveys is to use surveying techniques to conduct on-site application for rights submitted by the owners. Investigation and verification of the land, providing accurate and reliable proof of property rights for the legal determination of land rights.

(5) The technical standard of cadastral survey must meet the requirements of land law. The technical standard of cadastral survey must not only meet the surveying viewpoint, but also reflect the requirements of land law. It not only expresses the relationship between people and features, features, and the relationship between features, but also reflects and regulates people. The relationship between people and society with land property rights as the core.

(6) Cadastral survey work has a very strong current situation. Because social development and economic activities make land use and rights change frequently, and land management requires very strong current status of cadastral data, cadastral survey results must be updated in a timely manner, so cadastral survey work is more valuable than general basic surveying and mapping work. On the regular side, it is impossible to artificially fix the update cycle, and it can only reflect the actual changes in a timely and accurate manner. Cadastral surveying has always been involved in the dynamic changes in establishing, changing, and terminating land use and rights relations, and is one of the main techniques for maintaining the current status of cadastral data.

(7) Cadastral surveying techniques and methods are an application integration of today's surveying and mapping techniques and methods. Cadastral surveying technology is an integrated application of common surveying, digital surveying, photogrammetry and remote sensing, area surveying, error theory and balance, geodesy, spatial positioning technology and other technologies. According to the comprehensive requirements of land management and real estate management for graphics, data and books, different mapping techniques and methods are combined.

(8) The technical staff engaged in cadastral surveying should have rich knowledge of land management. Technical staff engaged in cadastral surveying should not only possess rich knowledge of surveying and mapping, but also have knowledge of real estate law and cadastral management. Cadastral survey work is very strict from organization to implementation. It requires surveying and mapping technicians to cooperate closely with cadastral investigators and work meticulously. ^[3]
