[0002] Land planning refers to the long-term arrangements for the rational use of land within a country or a certain region in accordance with the prospects and needs of economic development. Surveying and mapping benchmarks are needed during land inspections. Surveying and mapping benchmarks refer to measuring tools in the shape of poles painted with red and white paint. They are mainly used to indicate measuring points. Existing benchmarks generally use wooden benchmarks. During use, the benchmarks are inserted into the measuring points so that surveyors can accurately observe the measuring points.

[0003] In the prior art, a benchmark is inserted into a surveying point. However, when rain erodes the ground and causes the soil to become soft, the benchmark is easily caused to fall by other external forces such as wind. The support for the benchmark is unstable, which affects the user's planning, increases the user's workload, and wastes the user's time. Therefore, a land planning positioning device is proposed.
