The cadastral surveying can be classified into the cadastral detail surveying, the cadastral control point surveying and the cadastral confirmation surveying.
The boundary relocation surveying that the land boundaries are unmoved, the cadastral location surveying. urban planning line relocation surveying, subdivision surveying that the land boundaries are not moved. registration conversion surveying and initial registration surveying belong to the cadastral detail surveying.
The cadastral triangle (supplement) point surveying and the cadastral supplementary control point surveying belong to the cadastral control point surveying.
Boundary Relocation Surveying
The boundary relocation surveying is to relocate the boundary points registered in the cadastral register onto the surface of the land. This is mainly used to determine the boundary for construction or wall or define the boundary with the adjoining lands,
Cadastral Location Surveying
The cadastral location surveying is to indicate the location (point, line, parcel) or area that land, ground-structure and geographic features, etc occupy onto the floor plan, compared with the boundary registered in cadester and woodland map. This is mainly used to complete the building, confirm the occupied area and check the location of the structure.
Urban Planning Line Relocation Surveying
The urban planning line relocation surveying is to relocate the urban and county management planning line, such as the urban planning line, onto the surface of the land. This is mainly used to check the urban planning line or setback road line when approving the construction,
The subdivision surveying is to divide one lot registered in the cadastral register into two lots or more and register. This is mainly used to sell parts of the land or transfer its ownership or to get an construction approval for parts of the land
Registration Conversion Surveying
The registration conversion surveying is to register the land registered in the woodland register and woodland map in the land register and the land registration map. This is mainly used to get an approval for construction, the change of land shape and quality and development activity for the woodland.
Initial Registration Surveying
The initial registration surveying is to register the land newly developed or unregistered in the cadastral register in the cadastral register. This is mainly used to register the land newly developed by reclamation or unregistered.
Cadastral Triangle (Supplement) Point Surveying
The cadastral triangle (supplement) point surveying is to seek the location of the cadastral triangle (supplement) point which will be the basis of cadastral supplementary control point surveying and cadastral detail surveying.
Cadastral Supplementary Control Point Surveying
The cadastral supplementary control point surveying is to establish the supplementary control point which is the control point of the cadastral detail surveying.
Cadastral Confirmation Surveying
The cadastral confirmation surveying is to register the new mark of the land in the boundary point coordinates register, arising from the urban development project, the land development project and the readjustment of arable land and public waters reclamation.
