[0002] A water conservancy project is a project built to control and allocate natural surface water and groundwater to achieve the purpose of eliminating harm and promoting benefits. It is also called a water project. In the prior art, when a water conservancy project is constructed, it is necessary to survey and map it, and then draw it based on the surveying and mapping data. Generally, a drawing board is used to draw on the drawing on site. In order to obtain accurate data, repeated measurements and calculations are required, resulting in multiple versions of the drawing. Different construction projects in the same area require different drawings. When determining the construction location, it is necessary to refer to and compare the construction drawings of different projects to avoid overlapping construction locations. It is more troublesome to compare different drawings. After the two drawings overlap, the drawing below cannot be observed. When the drawings are flattened for comparison, the comparison of the same area is not clear. It is more laborious in the drawing and standardization process, resulting in low work efficiency.
