What is the principle of Land Meter?

Many friends who are not familiar with Land Meter may wonder: What is the principle of Land Meter? Why can we measure the area of ​​land just by walking around with the machine? Is there a laser scanning accessory inside? This article will reveal the working principle of Land Meter for you.

Working principle of Land Meter

In fact, the core technology of Land Meter for land measurement is the satellite positioning system.

Satellite positioning: GPS (Global Positioning System) determines the precise location of the device by receiving signals from at least four satellites. Each satellite sends its location and time information, and the GPS receiver determines the user's geographic coordinates (longitude, latitude and altitude) by calculating the time the signal propagates.

Path recording: During the measurement process, the user walks along the boundary of the land, and the GPS receiver continuously records the coordinates of each location point.

Data processing: Once enough coordinate points are collected, the device or corresponding software will use the data of these points for calculation. Commonly used algorithms, such as the polygon area calculation formula, can calculate the area of ​​the enclosed area based on the arrangement order of the coordinate points.

Results show: After the calculation is complete, the device will display the area of ​​the land and usually provide a map view to help users better understand the measured area.

Is there an upper limit to the land area that Land Meter can measure?

In fact, there is no upper limit to the land area that Land Meter can measure. Because it relies on the satellite positioning system, the larger the land area measured, the more accurate the data obtained will generally be. It is worth noting that we do not recommend measuring land less than 500 square meters, as this may result in a measurement error of about 1%, which will not achieve the expected results.

How accurate is Land Meter's measurement?

Generally speaking, Land Meter's measurement accuracy can reach the meter level. If the device is equipped with RTK function, it can provide sub-meter measurement accuracy.

Can Land Meter be used worldwide? Will there be signal reception problems?

Current satellite positioning technology is sufficient to support the reception of satellite signals worldwide, so land measurement functions can be performed normally even in remote wilderness. To ensure that good signal reception does not affect the measurement results, it is recommended that you measure outdoors in an open environment and avoid operating indoors or in places with dense tree canopies.
