The basic data on which the land area is calculated include: aerial remote sensing data, topographic maps, measured coordinates, and real-length side lengths. The method for calculating the land area includes calculating by the analytical method according to the measured coordinates, calculating by the geometry method according to the length of the actual measurement, and calculating the required elements from the map using the coordinate analysis method or the geometrical figure method; Grid or dot board, scanner directly on the map measurement. Based on the basic data and the calculation method, the obtained land area has different accuracy. In the land management work, what kind of land area should be based on what basic data and what methods should be used for scientific evaluation? What are the accuracy requirements for various measurement methods? At present, there are no clear system regulations.
The application of acremeters has been changed. In rural construction land, the length of the border and the correlation with the topographical features are measured independently by a steel ruler or a tape measure, and the land area is calculated independently by geometric figures. The registration and certification of collective land ownership shall be based on the survey results of the land use status; the large-scale topographic maps already mapped on the outskirts of the city may be used to adjust the boundaries of land ownership and land boundaries, and use planimeters, scanners, grids, and outlets. Plates, etc., independently measure the total land area and the classified land area.

Mu meter for land area measurement
Land management needs to involve the area of ​​land. Different professions have different requirements for the accuracy of land area. At present, the country does not have a comprehensive and complete technical standard for land area measurement that can meet various precision requirements. This is not only unfavorable to protect the legitimate rights and interests of land rights holders, but also is not conducive to improving the level of land management. The mu meter plays an important role in the determination of land area.
