How to measure the acres of land

1, meter scale measurement. First measure the width and length of the land, then multiply it to calculate how many square meters there are, and then convert the square meters into acres. This not only wastes time and energy, but also makes mistakes easily. At present, this method is only applicable to small plots of land.

2. Map operation method. Take the map from the relevant land and resources bureau and calculate it according to the proportion on the map. This method needs a lot of calculation, and requires high measurement accuracy, which is far from the fact. It is even more difficult to start when encountering irregular plots, and its accuracy is difficult to measure. This method has been replaced by a new generation of measurement methods.

3. Instrument method. The hand-held acre meter is used for measurement, and GPS satellite positioning can provide latitude and longitude information, get the coordinates of each point, and then calculate the length, area and other data through mathematical methods; It can measure the area of irregular plots, which is simple and convenient to operate, but it consumes manpower. Surveyors need to travel along the boundary of the plot, and it is easy to produce large errors if they encounter building occlusion or poor signal.

4. Software method. The app software for measuring mu can be used immediately after it is installed in the mobile phone. It can not only use satellite positioning measurement like Mu 'an meter, but also directly measure points on high-definition satellite maps, and also measure the driving area of vehicles, with high precision and intelligent calculation of perimeter and area. Only one mobile phone is needed to measure the area, and no extra cost is needed. The whole measurement process is intuitive and labor-saving. Really realized, standing in the field, you can measure the field area.
