The invention provides an automatic planning land checking method. The automatic planning land checking method comprises the steps of: performing graphic layer management, obtaining a remote sensing image as the underlying graph, and establishing a graphic layer coordinate system through the underlying graph; performing planning data loading, loading planning data in the graphic layer coordinate system, separating point, line and surface elements of the planning data into different vector graphic layers, and loading to the underlying graph; performing track management, obtaining the position point generated by a real-time GPS signal, drawing a track curve in a track graphic layer according to the position point, fitting the terrain contour in the underlying graph through the track curve, generating the surface element from the closed track curve, and storing the surface element in a new track graphic layer; and performing automatic checking, and calculating the difference size and thedifference position of the surface element of the planning data graphic layer and the surface element generated by the track curve. By means of the automatic planning land checking method, the electronic device, the storage medium and the system provided by the invention, the planning land checking efficiency can be effectively increased; the checking cost can be reduced; and thus, effective technical support is provided for checking the planning land in our country.
