Is Shangye Village in Sangzhou Town measuring fields? 2022

Shangye Village in Sangzhou Town is surveying fields.

So far, the methods of obtaining data from rural surveying and mapping are: 1, topographic map of engineering surveying field survey. 2. Traditional manned aerial survey and mapping topographic map. 3. Using UAV aerial photogrammetry technology to obtain topographic map data of the test area (new).

The first method: field measurement. This method can't provide the image base map, and the field survey needs a large number of field surveyors, so the cost is high, and the specific implementation will be greatly affected by the terrain and climate, so it is difficult to meet the construction period and quality requirements.

The second method: traditional manned aerial survey. The traditional manned aerial survey needs a series of work, such as airspace application and coordination with the airport, which is costly and cumbersome to operate.

The third method: UAV aerial photogrammetry. Compared with the other two measurement methods, UAV aerial photography has the advantages of low cost, convenient execution, high degree of automation, high precision and high efficiency.
