Land planning survey reasonably be required to save construction costs and speed up the progress.Therefore, the study of The calculations of land planning survey accuracy , calculation methods, practical range of conditions and problems are necessary.However, due to The calculations of land planning survey directly related to the construction side and the construction side of the economic benefits, plus the complexity of The calculations of land planning survey in actual project . The measurable results will often be questioned by both works sides.How to measure standardized earthwork soil is considered to be one of challenges now. Stripped open pit mine workload and expense budget are based on The calculations of land planning survey Calculate the amount of earthwork quickly and accurately has important practical value.This article describes
