What is land surveying and mapping, and what is surveying and mapping?

Land surveying and mapping is actually the surveying and mapping of land, which refers to the use of computer technology.

Based on optoelectronic technology, network communication technology, space science and information science, with global positioning system (GPS), remote sensing (RS) and geographic information system (GIS) as the technical core, the existing feature points and boundaries on the ground are obtained through measurement means to reflect the graphics and location information of the ground status quo, which are used for the planning, design and administrative management of engineering construction. Now that the country has carried out the first national geographic national monitoring, you can pay attention to it.

Land surveying and mapping refers to the use of computer technology, optoelectronic technology, network communication technology, space science, information science as the basis, with global positioning system (GPS), remote sensing (RS), geographic information system (GIS) as the core of technology, the existing feature points and boundaries on the ground, through the means of measurement to obtain the graphics and location information reflecting the current situation of the ground, for the planning, design and administrative management of engineering construction.

Main work content.

The main work is to carry out cadastral survey control points, boundary points of the field selection, burying rocks, and the use of theodolite and other instruments to observe the distance, horizontal angle, vertical angle and level measurement of the land and its appendages.

1.State border surveys;

1.cadastral surveys on their own or with other surveying teams;

2.Measurement of parcel area of each land use unit in the jurisdiction;

3.Lofting of land coordinate boundary sites;

4.sporadic repair, make-up test;

5.Resale of large-scale surveying and mapping projects, ** surveying and mapping data.

A general term for surveying and Behcifer plotting. Surveying, such as engineering land lofting, railway and highway alignment, the establishment of national basic control points, and so on. Drawing, mainly surveying topographic maps, engineering sections, etc.

Summary. Surveying and mapping is literally understood as surveying and mapping, which is based on computer technology, optoelectronic technology, network communication technology, space science, and information science, with global navigation satellite positioning system (GNSS), remote sensing (RS), and geographic information system (GIS) as the technical core. Surveying and mapping refers to the measurement, collection and mapping of the shape, size, spatial location and attributes of natural geographic elements or surface artificial facilities.

Surveying and mapping refers to the measurement, collection and mapping of the shape, size, spatial location and attributes of natural geographic elements or surface artificial facilities.

Professional DefinitionSurveying and Mapping Engineering mainly studies the basic knowledge and skills of surveying and mapping, spatial precision positioning and navigation, urban and engineering construction and surveying engineering, etc., and conducts the measurement of various information such as space, geomorphology, geological structure and draws topographic maps, and is often used in field operations. For example: exploration of mineral resources such as coal and oil, drawing of traffic maps, drawing of engineering renderings, etc.

The Provincial Bureau of Surveying and Mapping is a subordinate unit of the Provincial Department of Land and Resources, which belongs to the establishment of undertakings, and is usually rented by financial appropriations, and should be a unit with relatively stable income;

The Bureau of Surveying and Mapping conducts surveying and mapping of land and related projects, and is not responsible for land management matters; The organs of the Land Bureau belong to the administrative establishment, and their main function is to perform land management duties.

Surveying and mapping refers to the technology of collecting, processing, and utilizing geographic information and geospatial data, as well as converting these data into graphic and textual forms that can express geospatial relationships. It is a science and an applied technology that can be achieved through a geographic information system (GIS). The purpose of surveying and mapping is to collect, process, and analyze geospatial data in an accurate and fast way to produce accurate survey maps and graphs that provide reliable data and geospatial analysis reports to departments, engineers, and other decision-makers.

For example, surveying and mapping techniques can be used to plan urban construction, design transportation networks, identify geological structures, estimate floods, identify land use, study climate change, monitor environmental changes, and more.

It is not uncommon to see people on the road with a tripod measuring the graphics and position of the current situation on the ground.

Surveying and mapping is literally understood as surveying and mapping, which is based on computer technology, optoelectronic technology, network communication technology, space science, and information science, and takes global navigation and clear satellite positioning system (GNSS), remote sensing (RS), and geographic information system (GIS) as the technical core.

The existing feature points and boundaries of the ground are selected and the graphics and location information reflecting the current situation of the ground are obtained by means of surveying, which are used for engineering construction, planning and design, and administrative early infiltration management.

Development:

Surveying and mapping is to study the shape, size, and gravitational field of the earth and other planets, and the objects of research and mapping are very extensive, mainly including various features on the surface, landforms, underground geological structures, hydrology, mineral deposits, etc., such as mountains, rivers, houses, roads, vegetation, etc.

Surveying and mapping work is very important because surveying and mapping engineers must survey and draw topographic maps and provide other information before making decisions, planning and designing can be carried out before developing a piece of land or carrying out large-scale construction.

Usually the maps we see and the travel maps before the traffic debate are completed on the basis of surveying and mapping. Engaged in surveying and mapping work, often carry out field operations, and be mentally prepared to face a difficult environment.

<> "Hello friends, surveying and mapping is the scientific and technological work of measuring, analyzing, processing, displaying and managing the earth's surface topography, landforms, geographical locations, etc. Through surveying and mapping, a variety of spatial data can be obtained, including terrain elevation, roads, buildings, land use, underground pipelines and other information. <>

Surveying and mapping work includes a series of technical fields such as topographic survey, oceanographic survey, geodetic survey, engineering surveying, cadastral surveying, remote sensing and geodispersal banking information system. In modern society, surveying and mapping technology is widely used, not only in land use planning, urban planning, electric power, petroleum, communications, transportation and other industries, but also in environmental protection, emergency rescue, homeland security, energy development and other fields also play an important role.
